Salmon Migrate into Irrigation Canals in the Upper Basin

Following the removal of the four lower Klamath dams last year, Salmon have been spreading throughout the Upper Basin, including into irrigation canals - where they should not be. Typically fish screens are installed on diversions to keep fish out, particularly endangered species such as Coho salmon. While there have been agreements to implement such preventative measures in the Upper Basin, fish screens are not yet installed on most irrigation canals in the area. 

Irrigation districts and users have voiced disappointment in the lack of support from state and federal partners in implementing screening measures.

ODFW recently received 1.25 million dollars form the Oregon Lottery Bond to assist landowners screen installation, but demand has outpaced supply and funding.

In late 2024, the Klamath Basin Water Agreement Support Act, was introduced by Republican Congressman Cliff Bentz, R-Ore., companion legislation to Wyden’s Klamath Power and Facilities Agreement Support Act. The bill passed and was signed by the President in early 2025. It is intended to provide federal agencies with the authorities necessary to cover the costs of infrastructure upgrades and operation that provide both water for agriculture and environmental benefits - including fish screen - but it seems that funds have yet to be allocated or dispersed.
