Description In the Yakima River Basin (Basin), current water storage capacity is insufficient to meet projected water demand. Managed Aquifer Recharge (MAR) is a cost-effective method that increases water storage by adding surface water to aquifers when excess flows are available. This work supports the goals and objectives of the Yakima Basin Integrated Plan.

A recent MAR assessment identified locations suitable for project implementation based on qualifying characteristics (EA et al., 2020). Taneum Creek, Naneum Creek, Little Creek, and Big Creek identified as high-priority locations potentially suitable for MAR because they have suitable geology and a reasonable opportunity for property access. They also have good access to flows both from KRD Irrigation system and from potential seasonal flood flows and a good likelihood of in stream benefit of recharged water.

Empirical data on stream discharge and local groundwater conditions is necessary to increase confidence in further prioritizing and implementing MAR at identified sites. The objective of this study is to acquire real-time stream discharge rates at sites identified in the MAR assessment, the highest priority is Taneum Creek. These data will increase our understanding of water availability and occurrence in the Upper Yakima River Basin.

Data has been collected on the streams listed above since 2020 under Ecology agreement WRYBIP-1921-KittRD-0017. This QAPP expands that data gathering to other priority sites identified in the 2020 Assessment at Wenas, Cooke, Parke, Wilson, Robinson, Dry, Schnebly, Reecer, and Jones creeks in accordance with the 2022 amended project agreement.

This project QAPP is submitted for Ecology review and approval, in accordance with guidelines in Ecology Publication No. 17-11-013. This monitoring, combined with on-going monitoring being collected by others, will provide discharge data for source water for the 57 highest-ranking potential MAR locations
