County wide base flow monitoring for stream flow enhancement 

Funded by the California Wildlife Conservation Board (WCB) Streamflow Enhancement Program, CCSE is collecting and analyzing instream flow data across SLO County. The programs includes three primary components:

  • Low flow motioning during the spring and summer to determine which creeks are meeting minimum in-stream Environmental Water Demand (EWD). EWD estimates are based on the minimum flows needed to sustain steelhead Trout (Oncorhynchus mykiss).
  • High-flow monitoring in collaboration with the County of SLO and the Central Coast Water  Board.
  • Evaluating the effectiveness of Cal Poly's rainwater capture and storage tanks which where built to alleviate the use of riparian wells in Pennington Creek. 

The results will be utilized to prioritize and improve future in-stream low flow enhancement efforts.  In-stream flow enhancement strategies include rain water capture and storage,  peak flow diversion and storage, groundwater recharge, reconnecting floodplains, and grey water re-use.
