Questions & Answers

The Act provides a national policy and program to preserve and protect selected rivers, or segments of rivers, in their free-flowing condition in the National Wild & Scenic Rivers System.  Section 1(b) of the Act states:

It is hereby declared to be the policy of the United States that certain selected rivers of the Nation which, with their immediate environments possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic, cultural, or other similar values, shall be preserved in free-flowing condition, and that they and...

Most rivers have flexible boundaries to accommodate specific features and river values. (Refer to Establishment of Wild and Scenic River Boundaries (1998).)

Yes. In some river study authorizations Congress has required the study agency to work with state and local governments and the public to develop a CRMP in concert with the study process to assist in determination of the river’s suitability. Such pre-designation CRMPs have, in some cases, been adopted in the legislation adding the river to the National Wild & Scenic Rivers System. In cases where Congress has not authorized a pre-designation CRMP, agencies have taken the initiative to develop elements of the CRMP in the study report (pre-designation).

The need to amend a segment division should be identified as a management concern/public issue during the planning process and considered in establishment of the initial boundary. The proposed amendment associated with establishment of initial boundaries must be undertaken with full public input and disclosure and is often completed during development of the comprehensive river management plan (CRMP) as a basis to make a recommendation to Congress to amend the Wild & Scenic Rivers Act.

The river-administering agency can only recommend such a change to Congress. A subsequent...

Section 13(g) of the Wild & Scenic Rivers Act allows the granting of easements and rights-of-way within the boundaries of designated components in accordance with applicable laws, provided that the conditions attached to the grant are consistent with the purposes of the Wild & Scenic Rivers Act.

Any portion of a right-of-way project that includes federally assisted construction that may affect the river’s free-flowing condition—and is not automatically prohibited by the Wild & Scenic Rivers Act—is subject to an evaluation by the river-administering agency under Section...

Section 13(c) of the Wild & Scenic Rivers Act expressly reserves the quantity of water necessary to protect river values, including water quality and flow-dependent outstandingly remarkable values. This reservation of water is called a federal reserved water right and is generally adjudicated in a state court (e.g., basin-wide adjudication). River designation does not supersede existing, valid water rights.

Refer also to CRS Report for Congress, The Wild and Scenic Rivers Act and Federal Water Rights, by Cynthia Brougher (January 9, 2009).

No. Under the Wild & Scenic Rivers Act, the federal government has no authority to regulate or zone private lands. Land use controls on private lands are solely a matter of state and local zoning. Although the Wild & Scenic Rivers Act includes provisions encouraging the protection of river values through state and local governmental land use planning, there are no binding provisions on local governments. In the absence of state or local river protection provisions, the federal government may seek to protect values by providing technical assistance, entering into agreements with...

Protective management of federal lands in the river area begins at the time the river segment(s) has been found eligible.  The free-flowing condition, identified outstandingly remarkable values, and classification are protected to the extent authorized under law and subject to valid existing rights.  Affording adequate protection requires sound resource management decisions based on National Environmental Policy Act (NEPA) analysis.  Protective management should be initiated by the administering agency as soon as eligibility is determined.  Specific management...

Yes. Motorized access allowed prior to designation will, generally, be allowed post designation, subject to congressional intent and river management objectives. However, if motorized use adversely impacts a river’s water quality or outstandingly remarkable values, or if the use is not consistent with the river’s classification the route may be closed or regulated.

The continued legality of motorized use on land or water is best determined through the river management planning process, which considers factors such as impacts on river values, user demand for such motorized...

River-administering agencies must evaluate proposed water resources projects under the appropriate standard of Section 7. The evaluative standard for projects located within a wild and scenic river corridor, Section 5(a) study area, or qualifying Section 2(a)(ii) application area is whether the project would have a “direct and adverse effect.” The evaluative standard for projects located downstream, upstream, or on a tributary to a wild and scenic river corridor or Section 5(a) study area is whether the project would “invade the area or unreasonably diminish” for designated wild and scenic...

Wild and scenic river status does not provide federal authority to regulate private lands. The river-administering agency will cooperate with state and local agencies to appropriately monitor and evaluate activities on private land. If such activities (existing or potential) threaten or are incompatible with the values that contributed to the river’s designation, then, to the extent necessary, mitigation will be accomplished in cooperation with landowners and federal, state and local agencies.

The Act (Public Law 90-542; 16 U.S.C. 1271-1287) was signed on October 2, 1968. It has been amended many times, primarily to designate additional rivers and authorize additional rivers for study for possible inclusion.

Once such a river has been found eligible, the federal study agency should, to the extent it is authorized under the Wild & Scenic Rivers Act and subject to valid existing rights, ensure the river and the surrounding area are protected as a potential wild and scenic river pending a suitability determination.

Once such a river segment has been found to be ineligible, the agency will manage the river and its corridor based on the underlying management direction in its programmatic plan and need no longer protect it as a potential wild and scenic river.

Yes.  The federal agency should consider a wide variety of internal and external sources from which to identify potentially eligible rivers.  These sources may include:  American Rivers’ “Outstanding Rivers List,” statewide river inventories/assessments, published guidebooks, etc.  The important point is to develop and apply standardized criteria through a documented evaluation process for potential wild and scenic rivers.

No. Navigability determinations are based on factors other than wild and scenic river designation. Because of this, designation does not affect ownership of the submerged lands [or minerals lying] under the river.

Wild and scenic river designations generally cause property values to remain stable or increase. For example, see Economic Benefits of Conserved Rivers: An Annotated Bibliography (Porter, B., Collier, S., Becerra, N., and Schultz, J. 2001. National Park Service – Rivers and Trails Conservation and Assistance Program, Washington, DC. 27pp.).

Yes, a federal reserved water right is generally adjudicated in state court (e.g., basin-wide adjudication) in the western United States. It is less clear how federal reserved water rights are adjudicated in the eastern United States. Contact a staff expert and/or legal counsel when trying to protect water quantity.

Water law is a complex legal area, and water rights are a highly contentious issue. Whenever a water allocation issue arises, a river manager should consult with staff with water rights expertise and, as necessary, seek legal counsel....

No. The river study, enabling legislation, and subsequent management planning process will consider how best to protect river values while recognizing private property rights.

Yes, if they are consistent with management objectives for the river and do not degrade water quality or the outstandingly remarkable values for which the river was designated.

Rivers in Alaska outside of national parks and Elkhorn Creek in Oregon (640 acres per river mile) exceed the 320 acre average.

Designation may cause an increase in use along the river as new visitors seek it out. However, the wild and scenic river management requirements should ensure that any such increase will not damage resources on private property. If anything, there will be increased oversight after designation, discouraging littering, trespass and vandalism. Private landowners may continue to post their property with “No Trespassing” signs or require users to obtain landowner permission.

Yes. Under Section 5(a) of the Wild & Scenic Rivers Act, the public is involved in the study of rivers authorized by Congress. The report associated with a congressionally authorized study addresses subjects such as current status of land ownership and use in the area; reasonably foreseeable potential uses of land and water which would be affected by designation; the federal agency to administer the river if designated; and the ability of, and estimated costs to, state and local agencies to participate in the administration of such rivers. The public and state, local and tribal...

Boundaries are measured from the ordinary high water mark of the outermost stream channel. That is, boundaries will be measured from the outermost braid unless otherwise specified by Congress. This is typically considered during the suitability determination and in the development of the final river corridor boundary.

Through the various federal agencies’ land management planning processes and initiatives by the public, a significant number of rivers have been identified for study as potential additions to the National Wild & Scenic Rivers System. For example, the Nationwide Rivers Inventory (NRI), maintained by the National Park Service, has identified over 3,400 river segments as potential candidates for study and/or inclusion into the National System.

Local government entities are encouraged by federal management agencies to provide for the protection of wild and scenic river values in their land use plans, including the use of zoning and other land use measures.

State land-use requirements often require each local jurisdiction to address uses and activities within wild and scenic river areas in their planning updates. Such local planning may be carried out by comprehensive plan policies, zoning requirements, negotiations with landowners, or through other mechanisms.

Section 16(b) of the Act defines free-flowing as “existing or flowing in a natural condition without impoundment, diversion, straightening, rip-rapping, or other modification of the waterway. The existence, however, of low dams, diversion works and other minor structures at the time any river is proposed for inclusion in the national wild and scenic rivers system shall not automatically bar its consideration for such inclusion: Provided, that this shall not be construed to authorize, intend, or encourage future construction of such structures in components of the national wild and...

As provided in Sections 4(a) and 5(c) of the Wild & Scenic Rivers Act, the following factors should be considered and, as appropriate, documented as a basis for the suitability determination for each river.

1. Characteristics which do or do not make the area a worthy addition to the National Wild & Scenic Rivers System. These characteristics are described in the Wild & Scenic Rivers Act (see factors 2 through 7) and may include additional suitability factors (8 through 13).


2. The current status of land ownership and use in the area.


3. The...

No restrictions to private lands may be applied under the Wild & Scenic Rivers Act. Comprehensive river management plans may establish goals for new construction consistent with classification. There is a wide range of uses compatible with these classifications so long as the overall values and character of the river corridor is maintained. Any effect on private lands would be through state or local zoning. Federal acquisition of lands or development rights would require landowner compensation.

Generally, existing livestock grazing practices and related structures are not affected by designation. The Interagency Guidelines state that agricultural practices should be similar in nature and intensity to those present in the area at the time of designation, and that grazing may be compatible with all river classifications (wild, scenic or recreational). Grazing and other public uses may occur in a wild and scenic river corridor as long as the uses do not adversely impact or otherwise degrade the values for which a river was designated.

The economic impacts of implementing various alternatives should be addressed through the evaluation process to determine whether a river is a suitable addition to the National Wild & Scenic Rivers System or through the river management planning process, or a designated wild and scenic river. Economic issues, such as development and ecotourism, both inside and outside of potentially designated river corridors may be considered.

Section 6(a)(1) of the Wild & Scenic Rivers Act states:

The Secretary of the Interior and the Secretary of Agriculture are each authorized to acquire lands and interests in land within the authorized boundaries of any component of the national wild and scenic rivers system designated in Section 3 of this act . . . but he shall not acquire fee title to an average of more than 100 acres per mile on both sides of the rivers.

The Wild & Scenic Rivers Act authorizes fee title acquisition to the equivalent of about a 400 foot wide strip of land...

Circumstances where agencies should always seek information and advice from each other are:

1. In agency inventory and planning processes, and environmental analysis processes for aquatic ecosystems and regional watersheds; and,
2. When proposed actions have the potential of affecting other agency-administered portions of the river.

Some examples of other similar outstandingly remarkable values include botanical, hydrological, paleontological, scientific, or heritage values.

For rivers designated under Section 3(a) of the Wild & Scenic Rivers Act, a state’s responsibilities include:

• Regulating and enforcing fishing and hunting regulations.


• Adjudicating water rights and appropriation.


• Developing and administering water quality standards.


• Administering state land use regulations on non-federal lands.
• Managing state lands and facilities along the river (e.g., state highways, parks, forests).

Prior to 1986, Section 3(b) of the Wild & Scenic Rivers Act required the river-administering agency to “prepare a plan for necessary developments in connection with its administration in accordance with such classification.” Through a generic amendment of the Wild & Scenic Rivers Act in 1986, Section 3 was amended with a new subsection requiring a “comprehensive management plan . . . to provide for protection of the river values” (Section 3(d)(1)). The comprehensive river management plan (CRMP) must address:

1. Resource protection;


2. Development of lands...

Yes, the federal government may seek to control use on adjacent lands under very limited circumstances. The Constitution gives the federal government certain limited powers to control uses on state-owned lands that affect adjacent federal property. These powers may be exercised through the Property Clause, which provides that, “Congress shall have the power to make all needful rules and regulations respecting the territory or the property belonging to the United States.”

The federal government may also regulate use and/or activities occurring on the surface waters...

These facilities will be provided if they are consistent with the management plan for each river and if funds are available.

Federal lands within the boundaries of designated river areas (one-quarter mile—one-half mile for rivers in Alaska located outside national parks—from the bank on each side of the river) classified as wild are withdrawn from appropriation under the mining and mineral leasing laws by Sections 9(a) and 15(2) of the Wild & Scenic Rivers Act. Federal lands within the boundaries of designated river areas classified as scenic or recreational are not withdrawn under the Wild & Scenic Rivers Act from the mining and mineral leasing laws....

Yes. Congress has frequently added wild and scenic river status to rivers flowing through national parks, national wildlife refuges, and designated wilderness. Each designation recognizes distinct values for protection, and management objectives generally designed to not conflict. In some cases, wild and scenic river designations extend beyond the boundaries of other administrative or congressional area designations, thereby providing additional protection to the free-flowing condition and river values of the area. Section 10(b) of the Wild & Scenic Rivers Act addresses potential...

The CRMP for rivers designated on or after January 1, 1986, is to be completed within three full-fiscal years after the date of designation or as otherwise specified, with a notice of completion and availability published in the Federal Register. For rivers designated before this date, Section 3(d)(2) requires review of the CRMP to determine if it conforms to Section 3(d)(1). This provision allowed ten years to update pre-1986 plans through the planning processes of river-administering agencies. Note: This 10-year period expired January 1, 1996.

Yes. Legal descriptions along with a map are submitted to Congress in accordance with Sections 3(b) and (c) of the Wild & Scenic Rivers Act and are retained by the administering agency. Requests for maps should be made to the agency field offices which administer the specific study or designated river(s).

Most current uses and activities on rivers and adjoining federal lands may continue. Of primary consideration in any river or land-use limitation is the protection and enhancement of the free-flowing condition, water quality, and outstandingly remarkable value(s) that resulted in the river’s designation. Those uses that clearly threaten these values will be addressed in the planning process, or through site-specific environmental analyses on a case-by-case basis where federal lands are involved.

It is important to develop and apply standardized criteria through a documented evaluation process that may include a screening for potential wild and scenic rivers. If there doubt, evaluate the river according to the criteria in the Wild & Scenic Rivers Act, i.e., free-flowing condition and outstandingly remarkable values.

Section 16(b) of the Wild & Scenic Rivers Act, defines a “river” as “a flowing body of water . . . or portion, section, or tributary thereof. . . .”  “Free-flowing” is defined as “existing or flowing in natural condition without impoundment. . . .”  Therefore, any section of river with flowing water meets the technical definition of free flowing, even if impounded upstream.

The requirement for a comprehensive river management plan (CRMP), does not apply to state-administered, federally designated rivers. Federal land managers are responsible for protecting river values in all agency planning and management actions for any portion of a 2(a)(ii) river that flows on federal lands. In some cases, the petitioning state has a requirement for a plan. The existence of a state or local plan to protect river values is one of the factors considered by the National Park Service in its review of the 2(a)(ii) nomination for the Secretary.

Once such a river has been found eligible, the federal study agency should, to the extent it is authorized under various laws and subject to valid existing rights, ensure the river and the surrounding area are protected as a potential wild and scenic river pending a suitability determination.

No. However, all treatments must protect river values. Treatment methods that also include in-channel activity (e.g. dredging) are subject to review under Section 7(a) as water resources project.

No.  The Interagency Wild & Scenic River Guidelines state, “There are no specific requirements concerning the length or the flow of an eligible river segment.  A river segment is of sufficient length if, when managed as a wild, scenic or recreational river area, the outstandingly remarkable values are protected.  Flows are sufficient if they sustain or complement the outstandingly remarkable values for which the river was designated.

Corridor boundaries are established to protect the free-flowing condition, water quality, and outstandingly remarkable values for which the river was designated. Generally, the corridor width for designated rivers cannot exceed an average of 320 acres per mile which, if applied uniformly along the entire designated segment, is one-quarter of a mile (1,320 feet) on each side of the river. Boundaries may be wider or narrower, but are not to exceed the 320 acre average per mile per Section 3(b) of the Wild & Scenic Rivers Act without approval by Congress. The acreage of any islands...
