The San Pedro Creek Watershed Coalition is a
nonprofit 501(c)3 organization dedicated to protecting, enhancing
and maintaining the health of San Pedro Creek and its watershed
through monitoring, restoration, adaptive management and education.
The upper reaches of San Pedro Creek have healthy
riparian areas and winter flows that support migrating steelhead
trout. San Pedro is the only creek within 30 miles
of San Francisco providing this type of habitat. The most
significant physical impacts to the stream come from urbanization
in riparian areas, channelization of the lower reaches,
and the complete culverting of the North Fork in the 1970s.
Water quality problems appear to relate most significantly
to storm drain inputs, especially along the culverted North
