YBSA Monthly Report April 2023

Storage: Volume of water in the 5 reservoirs is at 56% capacity. The amount in storage now is 250,000 acre/feet less than last year and 200,000 acre/feet less than average. Spring snow melt and runoff will continue through the month of May which may prolong the content of stored water and may increase instream flow in the lower Yakima River. Snow water content is at 100% which means the amount of water depends on the size of the snow pack.

YBSA: Tom Carpenter, Jr., one of the most important leaders in the Yakima Basin, worked to develop an annual amount of water to be made available for agriculture and increasing and maintaining instream flow in the Yakima River for salmonoids. The Carpenter family was one of the early farmers to introduce hops to the Yakima Basin. Two decades ago, the Basin was in need of water and many farmers had to drill wells to maintain their crops. Tom’s goal was to provide enough water each year to eliminate the possibility of droughts. Now that Tom has passed we still have to continue with the work of solving the water needs in the Yakima Basin that he was so involved with.
