The Yakima Tributary Access and Habitat Program (YTAHP) works to restore anadromous salmonid fish runs that were historically present within the Yakima River Basin. YTAHP works directly with voluntary private landowners to remove barriers inhibiting fish passage, screen irrigation diversions, as well as implement instream and riparian habitat in the local tributaries to the Yakima River.

YTAHP is funded through grants from the Bonneville Power Administration and was established as a mechanism to aid private landowners to achieve compliance with laws requiring screening on irrigation withdrawals and to improve fish passage. It does this by working hand in hand with voluntary landowners by providing funding, planning, engineering, permitting, and construction needs.
