Description The primary objective of this study is to quantify supplementation water’s contribution to the underlying groundwater system. The complexity of alluvial fan channeling and extensive irrigation infrastructure, with high frequency monitoring on the fan, supports a secondary objective that includes estimating the timing of return flows and the interconnectivity to the underlying aquifer along individual creek reaches. This will provide additional characteristics of surface and groundwater interactions and perhaps allow for future targeted management applications along the fan.
This study benefits from currently operating high-frequency stream monitoring along the creek conducted by the Kittitas County Conservation District (KCCD) and the KRD as shown in Figure 2. The KRD sites include an ultrasonic bridge sensor and two in-stream data loggers, all outfitted with telemetry described in Ecology Agreement WRYBIP-2325-KittRd-00053.
