Nearly every diversion operated directly by the seven Districts includes a protective fish screen that meets state and federal standards. These screens prevent small fish from entering irrigation canals, enabling them to safely move downstream. With the major diversions screened, the Districts are turning their sights to the smaller diversions operated directly by their patrons. Some of these projects are groundbreaking.

Three Sisters Irrigation District teamed with the U.S.. Fores Service to completely eliminate fish blockage at its diversion structure, and construct innovative screens on its intake, thereby providing steelhead and resident trout safe, unobstructive access to several miles of Whychus Creek that were blocked for nearly a century.

Tumalo Irrigation District, in addition to their conserved water projects, has constructed new screens and ladders at their Ben and Tumalo Creek Diversions. These facilities allow fish to swim upstream and downstream over the diversions and keep fish, their eggs, and fry out of the irrigation canals and in the river.
