Well pump tests (12,876) in three Central California groundwater basins were characterized and described according to their spatial distribution.  The average overall pumping plant efficiency (wire-water, not including column losses and velocity head) was about 56%.  Characteristics such as drawdown, total dynamic heads, kW, and flow rate vary greatly between pumps within and between sub-basins.  This is the first well pump characterization of its type in California, although irrigation pump tests have been conducted for over 70 years in California.  This paper provides a summary of the spatial variation of well pump performance and characteristics.
