DESCRIPTION
Decommissioning the leaking and inefficient PUD irrigation system pipeline and delivery system and converting existing irrigation water users to wells will create water savings of 2.7 – 3.3 cfs between RM 3.45 and 1.7 (pipeline intake and outfall) and improve lower Entiat River instream flow conditions. To create improved off-channel habitat conditions year-round targeted at benefiting adult and juvenile steelhead (spring Chinook juveniles may also benefit), flows in the canal will be reduced 8-9 cfs, resulting in a savings of 8-9 cfs in the mainstem in the 0.15 mile between the canal diversion and outfall. The Entiat PUD Canal System Conversion Project is located in the lower portion (RM 0.0- RM16.2; Category 2 subwatershed) of the Entiat River in Chelan County. The canal runs along the Entiat River in T25 R20 Sec13 and T25 R21 Sec18 in Chelan County. The canal irrigation water canal diversion and return outfall are located approximately River Mile 3.45 miles and RM 1.49 miles, respectively. The Entiat PUD Canal System Conversion project will address water quantity and water quality issues, particularly late-season instream flows, help moderate stream temperature extremes and improve water quality in the lower Entiat, and facilitate salmonid access to spawning and rearing habitats. In addition, it complements the suite of habitat improvement actions implemented instream adjacent to and within the canal last year as part of Phase 1 of the Bridge-to-Bridge project.
The Cascade Conservation District decommissioned the leaking and inefficient PUD irrigation system pipeline and delivery system and converted existing irrigation water users to wells made progress towards creating water savings of 2.7 - 3.3 cfs between RM 3.45 and 1.7 (pipeline intake and outfall) and improving lower Entiat River instream flow conditions.

The Entiat PUD Canal System Conversion project will address water quantity and water quality issues, particularly late-season instream flows, help moderate stream temperature extremes and improve water quality in the lower Entiat, and facilitate salmonid access to spawning and rearing habitats. The water savings from this project will be enrolled in or dedicated to the Washington Water Trust program. In addition, it complements the suite of habitat improvement actions implemented instream adjacent to and within the canal last year as part of Phase 1 of the Bridge-to-Bridge project.
