## Facts

- A private utility applied to the Federal Power Commission (FPC) for a license to build and operate the Pelton hydroelectric project on the Deschutes River in Oregon.
- The project site lay on lands reserved by the United States for power purposes, including lands within the Warm Springs Indian Reservation and adjacent federal reservation lands.
- The proposed development included a large concrete dam and powerhouse; the reservoir would inundate certain lands titled in, or to be titled in, the United States.
- Oregon intervened, asserting the project would harm anadromous fish runs and arguing a federal license could not issue without state authorization and stronger fish-protection conditions.
- The FPC granted the license after finding the project served the public interest and that fish-conservation measures were adequate.
- The Ninth Circuit set aside the license, holding Oregon’s consent was required.
- The Supreme Court reviewed the case and reversed.

## Issues

1. Whether the Federal Power Act authorized the FPC to license a hydropower project located on federal reservation lands in a state.
2. Whether Oregon could require its consent as a condition to federal licensing of the project.
3. Whether the Acts of 1866 and 1870 and the Desert Land Act of 1877 limited federal licensing authority by preserving state control over the waters at issue.
4. Whether the FPC abused its discretion in approving the project’s fish-conservation provisions and determining the project served the public interest.

## Decision

- The Supreme Court reversed the Ninth Circuit and upheld the FPC’s license.
- The Court held the Federal Power Act applied according to its terms to the project on federal reservations.
- The Court held licensing authority for the project was within the FPC’s exclusive jurisdiction and did not require Oregon’s consent.
- The Court held the Acts of 1866 and 1870 and the Desert Land Act of 1877 did not apply because the license concerned use of waters on federal reservations rather than “public lands” subject to general disposal statutes.
- The Court found no abuse of discretion in the FPC’s approval of fish-conservation conditions.

## Legal Principles

- Under the Federal Power Act, Congress established a comprehensive federal licensing scheme for hydropower projects; states may not impose an additional consent requirement that effectively gives them final veto power.
- Federal authority to regulate and permit use of federal reservations and related project works rests on the Constitution’s Property Clause when the project is located on lands owned or controlled by the United States.
- General statutes governing disposal and use of the public domain do not control where lands have been withdrawn and reserved for a federal purpose; such statutes are inapplicable to federal reservations.
- Judicial review of the Commission’s public-interest balancing, including fish and wildlife protections, is limited; the license stands absent an abuse of discretion.

## Conclusion

The Court upheld federal primacy under the Federal Power Act for licensing hydropower projects on federal reservations, ruling that Oregon’s consent was not required and that the FPC acted within its statutory powers and discretion, including in its fish-conservation conditions.
