The San Francisquito Creek watershed is one of the largest draining into the south San Francisco Bay and is therefore responsible for containing and transporting many pollutants, including sediment. San Francisquito Creek provides habitat for both terrestrial and aquatic species, including the California red-;egged frog and steelhead trout that use the creek as a spawning ground. The Regional Water Quality Control Board (RWQCB) lists the beneficial uses of San Francisquito Creek as fish migration, fish spawning, warm and cold fresh water habitat, and potential contact and noncontact recreational uses (CRMP 1997). These features of the creek and its watershed have ignited concern for the future health of the creek and the species that it supports. In 1992, the Peninsula Conservation Center (PCC) developed the Coordinated Resource Management and Planning (CRMP) committee as a way to unite all the stakeholders and interested parties in the watershed. This approach, as defined by the CRMP (1997), is a wholistic [sic] approach which manages natural resources according to ecologically defined boundaries" and "is becoming recognized as ultimately more efficient than dealing with problems within the confines of city limits." As part of the watershed planning process, it is important to collect baseline data on basic water chemistry and water quality parameters so the current state of the creek is understood. Furthermore, by including a volunteer component to this process, the community is not only educated, but also involved The objective of this project was to collect baseline water quality and geomorphological data in the upper watershed of San Francisquito Creek to be used as a starting point for long-term monitoring. The specific objectives include the following: Conduct basic water chemistry volunteer monitoring in the upper reaches of San Francisquito Creek by utilizing pre-existing protocols. Collect data on the geomorphology of the upper San Francisquito Creek using longitudinal and cross-sectional surveys. Collect suspended sediment and flow data. Establish permanent benchmarks to enable the sampling and surveying locations to be easily relocated. Add to existing data already collected on San Francisquito Creek."
