Public Comment on Minidoka Water Extraction Compatibility Determination

Minidoka National Wildlife Refuge is seeking public review and comment on its Draft Compatibility Determinations for water extraction. We will accept comments received or postmarked on or before August 24th, 2026. 

The Service prepares Compatibility Determinations to ensure that public and economic uses of National Wildlife Refuges do not interfere with or detract from the purposes for which each refuge was established. Compatibility Determinations also describe how these uses would contribute towards achieving Refuge purposes and the mission of the National Wildlife Refuge System. 

You may submit comments or requests for additional information through any of the following methods: 
• Email addressed to: Southeast_Idaho_NWR@fws.gov; Include “Minidoka NWR Compatibility Determination” in the subject line of the message. 
• U.S. Mail addressed to: U.S. Fish and Wildlife Service, Attn: Jaime Allen, Refuge Manager, Minidoka National Wildlife Refuge, 961 E Minidoka Dam, Rupert, ID 83350

All comments received from individuals become part of the official public record. The Service’s practice is to make comments, including names and home addresses of respondents, available for public review during regular business hours. Individual respondents can request that we withhold their home address from the record, which we will honor to the extent allowable by law. If you wish to have your name and/or address withheld, you must state this prominently at the beginning of your comments.

Minidoka National Wildlife Refuge is located on the Snake River Plain in south-central Idaho, 12 miles northeast of Rupert. It includes 80 miles of shoreline around Lake Walcott, from Minidoka Dam upstream about 25 miles. The refuge headquarters is located in Lake Walcott State Park
