All of the water in Escondido Creek that flows through the Reserve enters the creek through the stormwater collection system in the City of Escondido. In times of low precipitation, the creek flows with urban runoff from Escondido.
Water in Olivenhain Reservoir is pumped in via a pipeline fed from Northern California and the Colorado River. Local rainfall does not have an impact on water level.
