Area History

San Elijo Lagoon was once a fully tidal system. When the lower Escondido Creek area was settled in the 1880s, the area began to undergo vegetational modifications, mainly due to farming and grazing influences. Between 1934 and 1973, sewage from various sources was discharged into the lagoon. And between 1937 and 1971, numerous dikes and levees were installed to construct duck ponds for hunting. Many of these can still be found within the lagoon. The property was acquired to preserve, protect and maintain the coastal wetland habitat and those species associated with this habitat type. It was designated as an ecological reserve by the Fish and Game Commission in 1983. More recent modifications of landforms and drainage patterns have also drastically altered the ecosystem.
