About the Project:

Diversion barrier at Storm Lake Creek

The Upper Clark Fork Initiative's goal is to maximize connectivity for fish passage within the watershed for native federally listed bull trout and state priority Westslope Cutthroat trout. The project will mainly address agricultural diversion dams and road crossings as a priority area for the State of Montana, this project will allow migratory access to upper elevation cold water refugia spawning grounds.   

These four private diversions are part of a decade long effort to open connectivity and together re-open 55 miles and 270 acres of critical habitat. The Lost Horse Creek project will replace a diversion with a rocky ramp, vanes and a screen. The Warm Springs and Storm Creek will add selective passage facilities and Twin Lakes will add a ramp and selective passage facility. In addition to benefitting the species, these projects will create stable diversions for local agriculture, buffering the community against potential loss of crops due to climate change climate change
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.

The National Fish Passage Program combines technical expertise with a track record of success. 

Implemented primarily through the Service's Fish and Wildlife Conservation Offices, the National Fish Passage Program provides financial and technical assistance to partners across the country. Since 1999, the program has worked with over 2,000 local communities, Tribes, and private landowners to remove or bypass over 3,400 barriers to fish passage and reopen access to over 61,000 miles of upstream habitat for fish and other animals. Staff have expertise in fish migration and biology as well as financial, engineering, and planning assistance to communities, Tribes, and landowners to help them remove barriers and restore rivers for the benefit both fish and people. 

Fish passage project proposals can be initiated by any individual, organization, government, or agency. However, proposals must be submitted and completed in cooperation with a Fish and Wildlife Conservation Office. (Please note that fish passage projects being used for federal or state compensatory mitigation or required by existing federal or state regulatory programs are not eligible for funding through the National Fish Passage Program.) 




The Fish Passage Program works with local communities on a voluntary basis to restore rivers and conserve our nation’s aquatic resources by removing or bypassing barriers. Our projects benefit both fish and people.
