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...

Corridors may not exceed an average of 320 acres per river mile over the designated portion of the river (except on certain other rivers as specified by Congress and in Alaska, which is 640 acres for rivers located outside national parks). Agencies delineate boundaries based on natural or manmade features (canyon rims, roads and ridge tops, etc.) and legally identifiable property lines.

Yes. Fishing and hunting are regulated under state laws. Where hunting and fishing were allowed prior to designation, they may continue. The river-administering Secretary may, however, designate no hunting zones or periods in which no hunting is allowed for public safety or other reasons. The Secretary must issue such regulation in consultation with the wildlife agency of the state(s).

Wild and scenic river designation seeks to protect and enhance a river’s current condition. Generally, the classification of the river reflects the level of development at the time of designation, and future development levels must be compatible with such classification. Any proposed new developments on federal lands must be guided by land use and resource management objectives that are compatible with the river’s classification.

Agency land use or resource management plan records should include documentation of the eligibility criteria, inventory process, evaluation, and outcome. Agency field offices retain the administrative record and documents related to an assessment of the free-flowing condition and identification of outstandingly remarkable values.

Yes.  The Nationwide Rivers Inventory lists potentially eligible rivers.  Federal agencies should make an eligibility determination for rivers on the Nationwide Rivers Inventory.

Subject to valid existing rights, rivers authorized for study under Section 5(a) of the Wild & Scenic Rivers Act are withdrawn under the mining laws while in study status; this withdrawal covers the bed and bank and federal lands situated within one-quarter mile of the bank on each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...

No. There are no special provisions limiting overflights of components of the National Wild & Scenic Rivers System. Certain designated wild and scenic rivers are located by coincidence within restricted overflight areas, but were not the cause of the restriction. Altitude restrictions for civil aircraft in the United States under Federal Aviation Administration (FAA) regulations (e.g, 14 CFR 91.119 and 91.515 which apply to U.S. airspace) and altitude guidelines in the Airman’s Information Manual (Section 4, paragraph 7-4-6) apply to certain chartered areas. The FAA has entered into...

The river-administering agency must take the actions necessary to remedy adverse impacts and/or show measurable progress in addressing identified adverse effects. The Wild & Scenic Rivers Act gives river-administering agencies authority to adjust or eliminate livestock grazing, or any other commercial use, if doing so is necessary to meet the protection and enhancement standard.

As of June 2022, some 226 river segments comprising 13,417 miles have been afforded protection in the National System.  These nationally recognized rivers comprise some of the nation’s greatest diversity of recreational, natural, and cultural resources, offering great scientific value and scenic beauty.  By comparison, more than 75,000 large dams across the country have modified at least 600,000 miles, or about 17% of America’s rivers (possibly more than 20% – figures are best estimates).

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...

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...

Yes. The “equal footing” principle of the Constitution and the Submerged Lands Act of 1953 afford each state the ownership of lands and natural resources under navigable rivers. These submerged lands generally extend from bank-to-bank or to the mean or ordinary high water mark.

Suitability is an assessment of factors to provide the basis for determining whether to recommend a river for addition to the National Wild & Scenic Rivers System. Suitability is designed to answer these questions:

1. Should the river’s free-flowing character, water quality, and outstandingly remarkable values (ORVs) be protected, or are one or more other uses important enough to warrant doing otherwise?


2. Will the river’s free-flowing character, water quality, and ORVs be protected through designation? Is it the best method for protecting the river corridor...

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.

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.

The Interagency Guidelines may be revised. The Interagency Wild & Scenic Rivers Council periodically evaluates tasks to be undertaken.

A range of projects are allowable to restore natural channel processes and habitat, including placement of limited rock and wood, native plantings to stabilize streambanks, and the removal or addition of fish barriers. Such projects are most likely to protect river values, including a river’s free-flowing condition, provided they: 

1. Mimic the effects of naturally occurring events such as trees falling in and across the river (including the formation of wood jams), boulders tumbling in or moving down the river course, exposure of bedrock outcrops, bank sloughing or...

Generally, no. Any provisions for public use of private lands must be specifically included in the terms of the easement. Depending upon the terms and conditions of each easement, public access rights may or may not be involved. For example, a scenic easement may only involve the protection of narrowly defined visual qualities with no provisions for public use. A trail or road easement by necessity may involve public use provisions.

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.

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...

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...

The federal wild and scenic river-administering agency is responsible for implementing the Wild & Scenic Rivers Act’s requirements, including the development of a comprehensive management plan for each river within three full fiscal years from the date of designation. It is also responsible to protect and enhance a river’s values, through its authorities on federal lands and through voluntary, cooperative strategies developed with other governments, tribal nations, and landowners on non-federal lands, and to evaluate water resources projects under Section 7(a).

Timber management activities on federal lands outside the corridor are managed to protect and enhance the values that caused the river to be designated. Measures needed to protect and enhance the river’s values are developed through the river planning process and include management direction as necessary for lands adjacent to the corridor.

Generally, existing agricultural and grazing practices, and related structures are not affected by designation. The Wild & Scenic Rivers Act does not give federal agencies authority to regulate private land. Consequently, the only effect of designation is to authorize the purchase of easements within the river corridor, and to enable federal agency staff to provide technical assistance to private landowners interested in reducing impacts on the river’s water quality and riparian integrity.

There are three instances when federal agencies assess eligibility: 1) at the request of Congress through specific authorized studies; 2) through their respective agency inventory and planning processes; or 3) during National Park Service evaluation of a Section 2(a)(ii) application by a state. River areas identified through the inventory phase are evaluated for their free-flowing condition and must possess at least one outstandingly remarkable value.

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

Section 16(b) of the Wild & Scenic Rivers Act defines a river as “a flowing body of water or estuary, or a section, portion, or tributary thereof, including rivers, streams, creeks, runs, kills, rills, and small lakes.”

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.

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.

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.

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.

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).

For 5(a) studies, the study report, planning document and combined National Environmental Policy Act (NEPA) analysis are submitted to the agency head for review and subsequent transmittal to Congress, which decides the final disposition of the river.

For 5(d)(1) studies, the study report and combined NEPA analysis (if conducted as a separate study), or study report prepared from the underlying land management plan, are submitted through the study agency and its respective department for review. The final study report is transmitted by the appropriate Secretary to Congress, which...

No, not unless necessary to protect public safety, the river’s water quality, or other resource values. Recreational use of our nation’s rivers is increasing in both magnitude and extent, i.e., the types of recreational activities pursued and the technologies being used. Whether and how to restrict recreational use is a key issue in the planning process, which includes extensive local, regional, and national public involvement.

To be eligible for designation, a river must be free-flowing and contain at least one "outstandingly remarkable value," i.e., scenic, recreational, geologic, fish and wildlife, historic, cultural, or other similar value.

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.).

Camping is often important to the enjoyment of wild and scenic rivers. As appropriate, and when private interests do not provide sufficient facilities, the federal managing agency attempts to provide them on federal lands. As a condition of use, consistent with river classification and the management objectives for the river area, the managing agency may specify that camping will be permitted only in designated locations. Enforcement of camping restrictions and limitations can be through indirect means (brochures, maps, signs, etc.) and/or direct means (permits, enforcement personnel, etc...

Benefits may include, but are not limited to, providing managers tools or mechanisms to protect free-flowing condition, i.e., protection of river values through the assessment of hydroelectric facilities or water resource development projects within the designated reach; protection and enhancement of water quality and outstandingly remarkable values; and, if a river’s management plan objective, promotion of economic development, tourism, or recreational use. Based on current limited studies, indications are that property values remain stable or increase on designated rivers. This is often...

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.

A Section 5(d)(1) study river is protected to the extent of each study agency’s authority and not by the Wild & Scenic Rivers Act. Each agency’s policy is to protect eligible rivers and rivers determined suitable for designation for the life of the respective agency land use plan. A river determined not suitable for designation need no longer be protected as a potential addition to the National Wild & Scenic Rivers System once the study, with its related decision document, is completed.

Agency officials are required to coordinate when their responsibilities relevant to wild and scenic rivers overlap.  Officials should determine the level of study to be conducted, who will lead the study, and, to the extent necessary and feasible, prepare a joint document for submission to Congress or congressional delegations.

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...

Existing powerline or communication transmission rights-of-way may continue to be used and maintained. New proposals would be evaluated for impacts to river values based on state and local zoning.

No. Lands owned by a state may be acquired only by donation or exchange per Section 6(a)(1) of the Wild & Scenic Rivers Act.

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.

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.

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.

Projects with the following attributes are generally considered most harmonious with river ecosystems:

• Those made of native materials, e.g., wood, rock, vegetation, and so forth that are similar in type, composition or species to those in the vicinity of the project.
• Those using construction materials that are natural in appearance, e.g., logs with bark intact as opposed to being peeled and whole naturally weathered rocks as opposed to split or fractured (i.e., riprap).
• Those with materials placed in locations, positions, and quantities mimicking natural...

Many individuals and communities support designation to help focus management efforts on protecting and enhancing river values. The intent of the Wild & Scenic Rivers Act is to build partnerships among landowners, river users, tribal nations and all levels of governments in developing goals for river protection. Designation provides strong protection against construction of new dams and projects that alter the free-flowing condition, water quality, and outstandingly remarkable values for which the river was designated.
