   ORDER

MOLLOY, Chief Judge.

Plaintiffs, Defendants, and Defendant-Intervenor have all filed motions for summary judgment in this matter. The following order is based on the Vaughn index filed with the Court and the parties’ briefs. Lion Raisins Inc. v. United States Dept. of Agriculture, 354 F.3d 1072, 2004 WL 63620, *5 (9th Cir.2004); Vaughn v. Rosen, 484 F.2d 820, 823-25 (D.C.Cir.1973).

I. Introduction & Factual Background

The Flathead Joint Board of Control (“Joint Board”) made Freedom of Information Act (“FOIA”) requests to the Bureau of Indian Affairs and the Bureau of Reclamation, both agencies within the United States Department of the Interior, to obtain information regarding the allocation of water rights on the Flathead Reservation, home of the Confederated Salish and Kootenai Tribes (“CSKT” or “Tribes”). The CSKT, the Joint Board, and the State of Montana are currently involved in a general stream adjudication process under the Montana Water Use Act (MCA § 85-2-101), which has been underway since the 1980s. Under Arizona v. San Carlos Apache Tribe, 463 U.S. 545, 103 S.Ct. 3201, 77 L.Ed.2d 837 (1983), states have jurisdiction to adjudicate the water rights of tribes within their boundaries. The United States is participating in the negotiations as part of its trust obligation to the Tribes. Joint Board of Control of the Flathead, Mission and Jocko Irrigation Districts v. United States and CSKT, 832 F.2d 1127, 1132 (9th Cir.1987). The information sought by the Joint Board was provided to the BIA and Bureau of Reclamation in association with this adjudication and the Tribes’ negotiations with the state.

The Tribes’ water rights are not of the same nature as irrigators’ water rights generally. The Tribes have reserved aboriginal fishing rights that entitle them to sufficient water to maintain the fisheries within the boundaries of the reservation, as well as to support other uses. This right precedes irrigators’ and other water rights on the Reservation under the “first in time, first in right” principle. United States v. Adair, 723 F.2d 1394 (9th Cir.1983), cert. denied, 467 U.S. 1252, 104 S.Ct. 3536, 82 L.Ed.2d 841 (1984). These fishing rights were obtained by the Tribes through the Hell Gate Treaty, which secured to the tribes “the exclusive right of taking fish in all the streams running through or bordering said reservation.” Treaty of July 16, 1855, 12 Stat. 975. Therefore, “[s]tate appropriative water rights and Indian reserved water rights differ in origin and definition. State-created water rights are defined and governed by state law. Indian reserved water rights are created or recognized by federal treaty, federal statute or executive order, and are governed by federal law.” State of Montana ex rel. Mike Greely v. Confederated Salish and Kootenai Tribes, 219 Mont. 76, 89, 712 P.2d 754 (Mont.1985) (internal citations omitted).

The Joint Board’s FOIA request is modeled after the successful request of a group called the Klamath Water Users in a similar dispute in Oregon. Department of the Interior and Bureau of Indian Affairs v. Klamath Water Users Protective Association, 532 U.S. 1, 121 S.Ct. 1060, 149 L.Ed.2d 87 (2001). In that case, the U.S. Supreme Court said that the DOI had to release irrigation information in its possession to the Water Users and could not rely on Exemption 5 to the FOIA (for intra-agency memoranda) as a way to avoid releasing the documents. The Tribes in this case distinguish their situation from that of the tribes in Klamath Water Users. The extent to which Klamath Water Users applies is at the heart of this dispute.

This Court denied Defendants’ motion to dismiss on November 26, 2002. The United States filed a Vaughn index on February 19, 2003. Before the Court now are motions for summary judgment by all parties.

II. Analysis

The Freedom of Information Act was intended to “pierce the veil of administrative secrecy and open agency action to the light of public scrutiny.” Department of the Air Force v. Rose, 425 U.S. 352, 361, 96 S.Ct. 1592, 48 L.Ed.2d 11 (1976) (citation omitted). “In reviewing de novo a grant of summary judgment for the government in a FOIA case, the court therefore remains mindful that the burden is on the agency to show that requested material falls within a FOIA exemption.” National Association of Home Builders v. Norton, 309 F.3d 26, 32 (D.C.Cir.2002) (internal quotations and citations omitted).

The United States has submitted a Vaughn index that describes each withheld document and identifies the FOIA exemption that permits withholding. There are many documents in the index that the Government now concedes should be disclosed. The dispute is over the applicability of two FOIA exemptions, Exemptions 4 and 5. -

A. Exemption 4

Exemption 4 covers, in part, “commercial or financial information obtained from a person and privileged or confidential.” 5 U.S.C. 552(b)(4). Thus, there are three essential characteristics of an exempt document. The parties disagree about what constitutes financial or commercial information. The real fight, Defendants argue, is whether various water rights and assessment information is accurately considered commercial and/or financial.

1. Commercial or financial

After National Association of Home Builders v. Norton, 309 F.3d 26 (D.C.Cir.2002), Plaintiffs claim that “natural resource information” generally is not protected by Exemption 4. The district court had granted summary judgment to the Secretary of the Interior on Exemption 6, claiming it prevented disclosure, but held that Exemptions 3, 4, and 5, did not cover the information. On appeal, the D.C. Circuit concluded that information about the location of endangered pygmy owls could not be withheld under Exemption 6, which protects “personnel and medical files and similar files the disclosure of which would constitute a clearly unwarranted invasion of personal privacy.” 5 U.S.C. § 552(b)(6).

The D.C. Circuit also agreed with the district court that Exemptions 4 and 5 did not apply and addressed those exemptions briefly. The Secretary had argued that Exemption 4 applied because the information was provided through government-to-government cooperation or agreement and that certain restrictions on its use made it commercial information. The Court disagreed, saying Exemption 4 was inapplicable. The New Mexico state agency that created the list was prevented by law from selling it. It was exchanged between the state and federal governments “quid pro quo,” which did not amount to a “commercial transaction in the ordinary sense.” “[T]he owl-sighting data itself is commercial neither by its nature (having been created by the government rather than in connection with a commercial enterprise) nor in its function (as there is no evidence that the parties who supplied the owl-sighting evidence have a commercial interest at stake in its disclosure.)” NAHB, at 38-39 (internal citations omitted).

Plaintiffs interpret this case broadly to cover “natural resource information.” However, the location of a non-commodity animal is, on its face, different from information generated through proprietary computer programs, regarding a commercial subject, and involving other information not readily obtainable by the public. Therefore, NAHB does not control this issue, as Plaintiffs argue.

In Public Citizen Health Research Group v. Food and Drug Administration, 704 F.2d 1280 (1983), the D.C. Circuit considered whether records produced during ongoing clinical trials of the safety and efficacy of intraocular lenses were protected under Exemption 4. The court concluded that “[bjecause documentation of the health and safety experience of their products will be instrumental in gaining marketing approval of them products, it seems clear that the manufacturers of IOLs have a commercial interest in the requested information.” Public Citizen, at 1291. The court did not precisely define commercial information, but it is apparent that commercial information need not be actively commercial at the time of assessment, but rather information that will in future be involved in commercial dealings.

None of these cases defines “commercial” except to rely on its plain meaning. In American Airlines, Inc. v. National Mediation Board, 588 F.2d 863, 870 (2nd Cir.1978), the court wrote “ ‘Commercial’ surely means pertaining or relating to or dealing with commerce,” stating there that “the commercial nature of the information is apparent.” No case deals specifically with Exemption 4 and water rights.

There is no doubt that water rights themselves are an object of commerce. They are a property interest that is bought and sold. There are usually limited water rights available. Therefore, information about the quantity available to a single holder, a holder’s use or priority date, or other similar information would be commercial information, used in negotiating real estate transactions, water leasing, and other commercial dealings. In the Tribes’ case, this including protecting a healthy fishery and the economic benefits that flow therefrom. The Joint Board seeks this information and water for commercial purposes, and CSKT is protecting it for commercial and financial purposes. The more difficult question here is to what extent the tools and strategies related to creating this commercial information are also, themselves, commercial information. In NAHB, the court made a distinction between information’s nature, that is, created by the government, and its function, having some commercial purpose preventing its disclosure. NAHB, 309 F.3d at 39. In this case, the nature of the information is not commercial, if, according to NAHB, information produced by a government is not. But the information leads to negotiation over a very valuable asset, and successful negotiations on the part of the Tribes will result in the Tribes having more of this valuable asset. Therefore, the information that creates the Tribes’ negotiating position, supports their claims, and results in maximizing the Tribes’ position is all commercial information in function.

2. From a person

“Person” is defined in FOIA to include “an individual, partnership, corporation, association, or public or private organization other than an agency.” 5 U.S.C. § 551(2). (“Agency” is defined as an authority of the United States government, with exceptions.) An Indian tribe “as a corporation that is not part of the Federal Government, is plainly a person within the meaning of the Act.” Indian Law Resource Center v. Dept. of the Interior, 477 F.Supp. 144, 146 (D.D.C.1979).

3. Privileged or confidential

What is confidential or privileged is defined by National Parks and Conservation Association v. Morton, 498 F.2d 765 (D.C.Cir.1974). Exemption 4 allows the government to garner important information to perform its functions. National Parks, at 767. “Apart from encouraging cooperation with the Government by persons having information useful to officials, section 552(b)(4) serves another distinct but equally important purpose. It protects persons who submit financial or commercial data to government agencies from the competitive disadvantages which would result from its publication.” National Parks, at 768. The National Parks test for confidentiality, therefore, is whether its disclosure would impede the Government’s functioning, and whether its disclosure would subject the person to a competitive disadvantage. National Parks, at 770.

The Ninth Circuit has discussed Exemption 4 only in the context of what is or should be confidential. (In both of the Ninth Circuit cases dealing with Exemption 4, the parties stipulated that the information was commercial in nature.) The Ninth Circuit adopted the D.C. Circuit’s National Parks test for confidential protection in GC Micro v. Defense Logistics Agency, 33 F.3d 1109, 1112 (9th Cir.1994). In Frazee v. U.S. Forest Service, 97 F.3d 367 (9th Cir.1996), the district court supported the Forest Service’s decision to release documents, against the plaintiffs reverse FOIA complaint. The Oregon district court based its decision in part on its determination, following in camera review, that the information contained in the documents was “publicly available and/or was taken directly from the Solicitation, from the Guidebook for Establishing and Managing Campground Concession Operations, or from other sources.” Frazee at 369-70. Therefore, the plaintiff could not argue that the information was truly confidential.

In this case, the information satisfies the National Parks test. The information helps the Government’s functioning, as its role as a trustee in the negotiation process is to maximize the Tribes’ negotiating position. Second, disclosure of the information will hurt the Tribes’ commercial position. In the Vaughn index, the United States describes four categories of documents that it considers exempt from disclosure under Exemption 4: 1. Information developed for the purpose of quantifying the Tribes’ instream water rights for fishing purposes; 2. Information regarding the development and use of computer models of the reservation’s water resources and the Tribes’ water needs; 3. Information regarding the development of the Tribes’ water rights claims for, and strategy in, the Montana Proceedings; and 4. Information regarding tribal budgets and funding proposals for the Tribes’ efforts to prepare for the Montana proceedings.

a. Category 1

Plaintiffs argue that water quantification is not commercial information. However, the Tribes, in developing a negotiating position with the State of Montana over the amount of their water rights, ought to be able to investigate the amount of water available to them as a part of creating their strategy.

An analogy might be to a manufacturer who will be negotiating for a contract to produce widgets. Information about the amount of widgets the company was capable of producing would clearly be commercial information exempt under Exemption 4. In order to figure out how many widgets can be produced, the company would have to evaluate its factories, its workforce, and its financial position. That information, if given to the government for some reason, would be exempt as it contributes to the business’ market competitiveness. Here, in order to negotiate and reach a compact with the state over water appropriations, the Tribes must be able to investigate what they have. In Joint Board of Control of the Flathead, Mission and Jocko Irrigation Districts v. United States and CSKT, 832 F.2d 1127, 1132 (9th Cir.1987), the Ninth Circuit wrote “[w]hile the Joint Board and junior appropriators are free to contest by legal means the Tribes’ and the BIA’s quantification of the Tribe’s fishing water rights, the Joint Board has produced, and we find, no authority that guarantees it a right to participate in the process by which the BIA and the Tribes initially establish that quantification.” After the Tribes and the State have reached an agreement, perhaps the Joint Board would have the right to contest the conclusion and provide counter evidence of quantification. However, at this point, the Government needs not disclose quantification methods that include data or lead to information about quantity.

b. Category 2

Category 2 includes information about the development of models for determining the Tribes’ water quantity. There are two types of information in the Vaughn index related to models-the information specifically related to the Tribes’ water rights, and other information related more generally to the computer model and what it does. The former is protectable because it is at the heart of the Tribes’ confidential information and strategy. The latter, if it is generic information about the HY-DROSS model, which I presume is commercially available and commonplace enough, is not protectable. Knowledge that the Tribes are using HYDROSS does not reveal information about the quantity of their water rights. There are a couple of documents in the index that fall into this latter category.

c. Category 3 (development of the Tribes’ water rights claims for, and strategy in, the Montana Proceedings)

This category is not specific numerical information, but, like .conversations held among board members trying to decide how to steer a corporation, it is tangled up with the commercial position of the Tribes. Therefore, it is protected.

d. Category 4 (tribal budgets and funding proposals for the Tribes’ efforts to prepare for the Montana proceedings)

Category 4 is the most straightforward Exemption 4 category. It includes financial information of the Tribes. As it includes financial information, it meets the first prong of the test. The further question of whether it was received from a person is also settled. The remaining issue is whether it qualifies as confidential. Generally the answer is yes, although there are a couple of documents that may not meet the second prong of the National Parks test — 'that is, the information may already have been revealed in public documents or public fora.

B. Exemption 5

Exemption 5 allows the government not to disclose “inter-agency or intraagency memorandums or letters which would not be available by law to a party other than an agency in litigation with the agency.” 5 U.S.C. § 552(b)(5). The United States Supreme Court discussed Exemption 5 in depth in Department of the Interior v. Klamath Water Users Protective Association, 532 U.S. 1, 121 S.Ct. 1060, 149 L.Ed.2d 87 (2001). The Court considered both elements of the provision: whether the documents are inter/intra-agency, and what protections are available if they are.

The issue in Klamath was the application of the first element, whether information given up by the Klamath Tribe qualified as “inter- or intra-agency.” In Klamath, the Court relied on the definition of agency as found in § 551(1) and 552(f): “each authority of the Government of the United States, ... [which] includes any executive department, military department, Government corporation, Government controlled corporation, or other establishment in the executive branch of the Government ..., or any independent regulatory agency.” Klamath Water Users, at 9, 121 S.Ct. 1060. Independent consultants with no interests of their own are included in the scope of this protection, on the principle that the agency should be able to request, in confidence, greater authority on a particular topic than its own agents possess. Klamath Water Users, at 11, 121 S.Ct. 1060; Soucie v. David, 448 F.2d 1067 (D.C.Cir.1971). In Klamath, the Tribe relied on this consultants’ corollary to Exemption 5 for its communications to the DOI, but the Supreme Court rejected the argument. The Tribe could not be construed as an impartial consultant, and therefore, the intra-/inter-agency exemption was foreclosed.

The second element — what is protected in litigation — is defined by civil discovery privileges. Klamath Water Users, at 8, 121 S.Ct. 1060; Schlefer v. U.S., 702 F.2d 233 (D.C.Cir.1983). These privileges protect attorney-client communication, attorney work product, and agency and executive deliberative processes. Klamath Water Users, at 8, 121 S.Ct. 1060; Dow Jones & Co., Inc. v. Department of Justice, 917 F.2d 571, 573 (D.C.Cir.1990).

The Vaughn index identifies several categories of information withheld under Exemption 5. These include 1.) federal officials’ notes, reports, and other mental impressions, 2.) water rights claim information, 3.) federal attorney’s legal deliberations and advice, and federal agency official’s requests therefore, 4.) discussion papers, work plans, status reports, briefings, and opinion papers, 5.) federal deliberative documents concerning contracts and funding for the preparations for the Montana Proceedings, and 6.) draft documents. Several of these categories are undoubtedly protected under Exemption 5, as documents generated by a government agency, for a government agency.

There are a few, however, that pose a problem under the Court’s ruling in Kla-math. Some number of the documents were generated by and for federal agents for their own use and then disseminated to the Tribes. Generally, a document from a federal agency to an outside party is not protected under Exemption 5. Dow Jones & Co., Inc. v. Department of Justice, 917 F.2d 571, 574 (D.C.Cir.1990). Sometimes a document that is released to a Congressional actor as part of the releasing agency’s deliberative process may be protected. Rockwell International Corp. v. U.S. Dept. of Justice, 235 F.3d 598, 604 (D.C.Cir. 2001). However, that exception appears limited to disclosures to Congressional entities. Disclosure to the CSKT would not qualify for this exemption as part of an agency’s deliberative process. However, a few documents are withheld under both exemptions and are not directed disclosed here, despite a failure under qualify under Exemption 5, because Exemption 4 suffices.

1.) Federal officials’ notes, reports, and other mental impressions

These documents are properly protected by Exemption 5, both under deliberative process privilege and, occasionally, attorney-client or work product privilege. However, the few documents listed in the Vaughn index that were disclosed to the CSKT are not exempt.

2.) Water rights claim information

This information is slightly different in the Government’s hands than it is in the Tribes’. The Tribes rely on Exemption 4 for this information, because the Tribes have a real commercial and financial interest in the outcome of this proceeding. The Government does not have the same interest, even though, due to its trust obligation, it must assist the Tribes as if it did. The Government has Exemption 5 protection of this information insofar as it is involved in litigation over the Tribes’ water rights and its thought-processes, deliberations, and communication related to that litigation are privileged information. ... [Deliberative process covers “documents reflecting advisory opinions, recommendations and deliberations comprising part of a process by which governmental decisions and policies are formulated.” Klamath at 8, 121 S.Ct. 1060 (citing N.L.R.B. v. Sears, Roebuck, & Co., 421 U.S. 132, 150, 95 S.Ct. 1504, 44 L.Ed.2d 29 (1975) (internal quotation marks omitted).)

3.) Federal attorney’s legal deliberations and advice, and federal agency official’s requests therefore

This information is exempt from disclosure as-not discoverable under regular civil discovery procedures.

4.) discussion papers, work plans, status reports, briefings, and opinion papers

These documents are exempt as deliberative process and interagency memos.

5.) federal deliberative documents concerning contracts and funding for the preparations for the Montana Proceedings

These documents would not be discoverable by a party in litigation with the agency.

F.) Draft documents.

Draft documents fall within the deliberative process exemption of FOIA. National Wildlife Federation v. U.S. Forest Service, 861 F.2d 1114 (9th Cir.1988); Russell v. Department of the Air Force, 682 F.2d 1045 (D.C.Cir.1982).

III. Documents to be disclosed

In accordance with the foregoing analysis, most of the documents listed in the Vaughn index supplied by the United States are properly withheld. A number of documents were originally in the Administrative Record but the Vaughn index indicates they have since been disclosed or that the Government concedes they are not properly withheld. If these documents are not already disclosed, they are directed to be so.

There are a few documents that are not properly withheld and must be disclosed. The following documents in the Vaughn index shall be disclosed: ■

IV. Conclusion

Based on the foregoing, it is HEREBY ORDERED that:

The Defendant United States’ and Defendant-Intervenor Confederated Salish and Kootenai Tribes’ motions for summary judgment (dkt##49 & 46) are GRANTED. Plaintiffs’ motion for summary judgment (dkt # 53) is DENIED.

The Clerk of Court is directed to enter judgment accordingly and to notify the parties of the making of this Order. The United States shall disclose the documents listed in Section III above. 
      
      . The Tribes and the U.S. argue that the Joint Board conceded elements two and three of the test-obtained from a person and privileged or confidential-by not responding to those issues in its briefs. U.S. Response Br., 5.
     
      
      . Klamath Water Users dealt only with Exemption 5 and is therefore inapposite to this section.
     
      
      . Non-tribal water rights information in Montana is a matter of public record. See the Montana Department of Natural Resources and Conservation's webpage at http:// www.dnrc.state.mt.us/wrd/home.htm, which provides public access to extensive water right information, including the owner's name, the amount of water allowed, and its source. Therefore, water rights information is commercial but in Montana would not meet the confidential prong to qualify for Exemption 4 non-disclosure.
