Relevancy to your project
The Yucaipa Groundwater Basin has been studied • Percolation analysis
extensively since the 1970s by the USGS and consultants • Update groundwater model
working for the Yucaipa Valley Water District (YVWD) and • Same Basin
Valley District. Prior to this project, our team re-evaluated
sub-basin boundaries within the basin. Subsequently, we
re-calculated the long-term sustainable yield for each sub-
basin using the updated sub-basin boundaries. We also
determined groundwater in storage and usable storage
capacity for each sub-basin for the years 2005 through
2014. The calculation provided baseline data to evaluate
the effectiveness of long-term groundwater management
in the sub-basins and accounts for surface water spreading
operations.
