Abstract : Mugu Lagoon is significant as one of the least disturbed and best protected estuaries in southern California; thus, this small estuarine system can serve as a baseline model for the region. This report summarizes and synthesizes scientific data on the ecological structure and functioning of the estuary, including discussions of climate, hydrology, geology, physiography, biotic assemblages, and ecological processes and interactions. The estuary exhibits extreme variability in freshwater inputs, being at times totally marine and at other times flushed by stormwater runoff from the watershed. Major storms in 1978 and 1980 resulted in sedimentation that drastically altered benthic communities and resulted in changes in the distribution of submerged aquatic vegetation and benthos, and fish and shorebird use of these food resources. Mugu Lagoon is part of a naval base and therefore not subject to the development pressures facing many other southern California estuaries. Storm-produced sedimentation remains a management concern, as well as closure of the mouth of the lagoon due to littoral drift of sand along the barrier spit.
