Questions & Answers

The Wild & Scenic Rivers Act requires that detailed boundaries portrayed on maps be established and submitted to Congress within one year of designation. Agencies may finalize boundaries through their respective land management planning process.

Pending the establishment of detailed river boundaries, the Wild & Scenic Rivers Act specifies that the interim boundary is one-quarter mile on each side of the river as measured from the ordinary high water mark.

Section 3(b) of the Wild & Scenic Rivers Act states:

The agency charged with the...

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...

Yes it may. Once water rights are adjudicated, the federal reserved water right may affect future water development projects, depending upon the impacts of the new proposal on the river’s flow-dependent values. Adjudications have been completed or are in process on 15 designated wild and scenic rivers. To date, existing flows have been sufficient to protect current and future demands and to meet the purposes for which the river was designated. River-administering agencies can work with local and state agencies to negotiate solutions that accommodate future water needs and that protect wild...

Yes. The Wild & Scenic Rivers Act anticipates the need for occasional adjustment of the lateral (river corridor) boundary, directing that such amendment follow the same process as described for the initial boundary development in Sections 3(b) and (c) of the Wild & Scenic Rivers Act. The legally established river corridor might require amendment to better reflect protection of outstandingly remarkable values or as the result of identification of a new outstandingly remarkable value.

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 following summarizes the sections of the Wild & Scenic Rivers Act related to water resources (quality and quantity):

Section 1(b) of the Wild & Scenic Rivers Act establishes that the national policy of dam and other construction be complemented by a policy that would preserve other selected rivers or sections thereof “in their free-flowing condition to protect the water quality of such rivers and to fulfill other vital national conservation purposes.”

Section 10(a) states: “Each component of the national wild and scenic rivers system shall be administered in...

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....

Citizen stewards are increasingly important in protecting wild and scenic river values, often through river-specific or regional stewardship organizations. Individually, or through nonprofit entities, citizens help survey and monitor resource conditions, provide interpretive and education opportunities, contribute to restoration efforts, and support many other protection activities.

Yes. Water may be secured through a variety of protection strategies, in the interim. Ultimately, the United States should secure a federal reserved water right in state court or the appropriate forum. Interim measures may include, but are not limited to: state instream flow programs, reservoir operation schedules, endangered species flow recommendations, conservation techniques, cooperative agreements, and water right purchases from willing sellers.

Water law is a complex legal area, and water rights are a highly contentious issue. Whenever a water...

Yes. There is no acreage limitation for less than fee title (e.g., easements), however.

In many cases, there may be no practical effect. However, laws like the Wilderness Act do allow certain activities in designated wilderness which may be incompatible on a wild and scenic river, e.g., water resource developments if authorized by the President. In addition, wild and scenic river designation prohibits federal participation in, or assistance to, water resource developments upstream or downstream of a designated river (potentially outside the wilderness area) which may adversely affect the designated river segment. Agencies are required by policy and law to evaluate potential...

In the Wild & Scenic Rivers Act, river values identified include scenic, recreational, geologic, fish and wildlife, historic, cultural, or other similar values. The Wild & Scenic Rivers Act does not further define outstandingly remarkable values. However, agency resource professionals have developed interpretive criteria for evaluating river values (unique, rare, or exemplary) based on professional judgment on a regional, physiographic, or geographic comparative basis. (Refer to The Wild & Scenic River Study Process (1999).)

Yes. Regardless of whether a river is designated as a wild and scenic river, states have special responsibilities and management constraints with respect to state-owned lands underlying navigable waters. These special responsibilities arise from the Public Trust Doctrine, which requires states to exercise regulatory authority over navigable riverbeds to ensure that the paramount right of public use of the rivers and riverbeds for navigation, commerce, recreation, and related purposes is not substantially impaired. As a matter of common law, the states hold lands...

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...

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...

When Congress proposes a bill to designate an eligible river for which a suitability study has not been completed, the potential river-administering agency should endeavor to:

1. Describe the resource and social factors typically evaluated in a study;
2. Identify potential issues; and
3. Assess its ability to manage the recommended component as a wild and scenic river.

This information provides the basis for the Administration’s decision to support or oppose the proposed designation.

Yes. Section 6(b) of the Wild & Scenic Rivers Act specifically prohibits the use of condemnation for fee title purchase of private lands if 50 percent or more of the acreage within the boundaries on both sides of the designated river is in public ownership (i.e., owned by the federal, state, or local government). In addition, Section 6(a)(1) of the Wild & Scenic Rivers Act prohibits acquiring more than 100 acres per river mile within the corridor, which equates to a stip of land about 400-feet wide along both sides of the river. Fee title condemnation is allowed to clear title or...

A primary objective of wild and scenic river designation is to protect and enhance riparian area function and other river-related natural values. Specific actions to meet the objective are typically set forth in the management plan required for each river.

Prior to completion of the CRMP, proposed projects and new decisions (e.g., issuance of a special-use permit) on federal lands are evaluated by the wild and scenic river-administering agency to ensure they protect and, to the extent possible, enhance river values (free-flowing condition, water quality and outstandingly remarkable values). The necessary evaluation framework is a detailed description of the existing conditions of these values at the time of designation. Absent this information it may not be possible to evaluate the effects of an activity relative to the non-degradation and...

No. The public’s right to float a particular river does not change with designation. Neither does designation give river users the right to use, occupy, or cross private property without permission.

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.

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

. . . the appropriate Secretary shall issue guidelines, specifying standards for local zoning ordinances, which are consistent with the purposes of this Act. The standards specified in such guidelines shall have the object of (a) prohibiting new commercial or industrial uses other than commercial or industrial uses which are consistent with the purposes of this Act, and (b) the protection of the bank lands by means of acreage, frontage, and setback requirements on development.

The Wild...

The Wild & Scenic Rivers Act states that rivers designated under Section 2(a)(ii) “shall be administered by the State or political subdivision thereof without expense to the United States other than for administration and management of federally owned lands.” The state is responsible for providing protection, except on federally administered lands and with respect to Section 7(a) determinations and securing a federal reserved water right under Section 13(c), both of which are made by a federal agency. The National Park Service provides ongoing technical assistance and partnership...

In agency parlance used for planning purposes, river “areas” include the entire length of a study or designated river and its adjacent lands, an average of 320 acres per river mile (except on certain other rivers as specified by Congress and in Alaska, which is 640 acres for rivers located outside national parks). A river “segment” is a portion of the river area which has been delineated for evaluation and planning purposes. Its subsequent classification is dependent upon the level of development of the shoreline, watercourse and access at the time of designation. Significantly different...

(*For certain rivers, Congress directed the river-administering agency in Section 3(b) to determine which classes “best fit the river or its various segments.”  These administratively segmented rivers should reflect on-the-ground practicalities and, therefore, are unlikely to require subsequent amendment.)

Yes. While Congress specifies the segment divisions of a designated river, in some instances congressional language may require interpretation. For example, a segment division between a wild and scenic classification described as “from the bridge”...

Regardless of the study agency’s eligibility and suitability findings, a Section 5(a) study river is protected by the conditions and restrictions specified in Sections 7(b), 8(b), 9(b), and 12(a) of the Wild & Scenic Rivers Act during the period of the study, plus up to three years after the required report is submitted to Congress. In other words, these protections are independent of the recommendation of the study, allowing for Congressional consideration.

The Wild & Scenic Rivers Act does not specifically mention aquatic or upland non-indigenous species. While non-indigenous species may be introduced—provided that doing so is not contrary to another law or the policy of the managing agency, and would not result in the degradation to the river’s values—the use of native species is generally preferred. Indirect impacts of introducing non-indigenous species, e.g., increasing recreational fishing, should also be considered. Additional guidance for a specific river is usually included in its management plan.

Subject to valid existing rights, rivers authorized for study under Section 5(a) of the Wild & Scenic Rivers Act are withdrawn under the mining laws while in study status; this withdrawal covers the bed and bank and federal lands situated within one-quarter mile of the bank on each side of the river. River study areas are not withdrawn from mineral leasing but are subject to conditions determined by the appropriate Secretary necessary to safeguard the area during the study period. However, the bed and bank and federal lands within two miles of the bank of each side of the rivers...

The communities of interest are key players in the development of a CRMP. They help with data collection and establishing baseline conditions, identifying issues and opportunities to be addressed in the planning process and, increasingly, in monitoring and implementation of aspects of the CRMP. Sections 10(e) and 11(b)(1) of the Wild & Scenic Rivers Act anticipate the participation of federal, state or local governments, landowners, private organizations and/or individuals in planning, protecting and administering wild and scenic rivers.

Amending the lateral boundary of a designated river requires analysis and decision under the National Environmental Policy Act (NEPA). The environmental analysis process need not be complicated and may only require the proposed action and a no-action alternative. Amendment of a wild and scenic river boundary may also be timed with revision of the comprehensive river management plan and related decision under the NEPA. In either case, notice of the amended boundary should be published in the Federal Register and the legal description and maps forwarded to Congress and made...

Maintenance of roads generally would not be affected. In consultation with landowners involved through coordinated management planning, every effort would be made to eliminate or reduce adverse impacts from any proposals for road improvement, realignment and/or new construction. If a proposed new road would have a negative impact on river values, the administering agency will work with the landowner(s) to mitigate the proposal. Should mitigation and/or consultation fail to reduce adverse impacts to an acceptable level, the administering agency could negotiate with the landowner to purchase...

There are a number of steps that federal agencies use in their evaluation process:

• Assessment of free-flowing condition and resource values.
• Finding of eligibility or ineligibility.
• Inventoried or tentative classification based on the development of shoreline, watercourse, and access.
• Establishment of tentative, preliminary, or proposed boundaries and/or river areas.
• Establishment of protective management requirements for eligible rivers.

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...

The federal government has rarely exercised its eminent domain powers with respect to wild and scenic rivers. Of the 226 rivers in the National Wild & Scenic Rivers System as of June 2022, condemnation for fee title has been used on only four rivers. Nearly all of the federal government’s use of condemnation occurred in the early years of the Wild & Scenic Rivers Act’s implementation when the attitudinal climate was one of federal acquisition. Similarly, the use of scenic easement condemnation has also been used very rarely, and then only on seven rivers, all designated prior to...

Yes. While Congress specifies the termini of a designated river, in some instances congressional language may require interpretation. For example, a terminus described as “from the dam” could be interpreted as including the dam and dam-related facilities. However, to allow for continued dam maintenance, it may be appropriate to establish the boundary a very short distance below the dam or, through specific language, to exclude appurtenant facilities.

The river administrator is well advised to consider on-the-ground practicalities at the initial boundary setting stage, to the extent...

Yes.  For purposes of eligibility evaluation, the volume of flow is sufficient if it is enough to sustain or complement the outstandingly remarkable values identified within the segment.  Rivers with intermittent or non-perennial flows exist within the National Wild & Scenic Rivers System and may be representative of rivers within particular physiographic regions.

Examples include, but are not limited to, bank stabilization/revetments; bridges (e.g., abutments, piers, approaches); emergency repairs; channelization; channel restoration; culverts; dams and dam removal; dredging or excavation; fish habitat/passage restoration or enhancement; gravel mining; in-channel transmission towers; levees; pipelines; recreation facilities such as boat ramps and fishing piers; water diversions/wells; and activities that are authorized under Section 404 of the Clean Water Act by the United States Army Corps of Engineers (ACOE).

Review of...

Yes, but with many restrictions. It is important to note that condemnation is a tool that has been used only rarely on wild and scenic rivers. The objective of wild and scenic river designation is to protect and, as possible, enhance the values which caused the river to be designated. Should some proposed or actual use clearly threaten the values the river was designated to protect, the river managing agency would work with a landowner to explore ways to avert the threat through local zoning, state provisions, land exchanges, or purchases on a willing-seller/willing-buyer basis....

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).

Yes, per Sections 3(b) and 15(1) for rivers designated by Congress under Section 3(a), but not for rivers designated by the Secretary of the Interior under Section 2(a)(ii). For 2(a)(ii) rivers, states and/or local government set the boundaries, if any, for rivers in their systems; these rivers are not subject to Section 3(b) or the 320/640-acre limitation.

The Wild & Scenic Rivers Act expressly prohibits the Federal Energy Regulatory Commission (FERC) from licensing the construction of a hydroelectric project or project works (e.g., facilities such as the powerhouse, access roads, transmission lines) under Part 1 of the Federal Power Act “on or directly affecting” a designated wild and scenic river. However, on the few rivers with a FERC-licensed hydroelectric project/project works within the river’s boundaries at the time of designation, existing operations may continue.

Relicensing of existing FERC-licensed hydroelectric...
