This report summarizes Water Year 2007 (10/1/2006 – 9/30/2007) water quality data for the San Francisco Bay Area Network (SFAN) Freshwater Quality Monitoring Program. The SFAN includes Eugene O’Neill (EUON), John Muir (JOMU), and Fort Point (FOPO) National Historic Sites, the Presidio of San Francisco (PRES), Muir Woods (MUWO) and Pinnacles National (PINN) Monuments, Point Reyes National Seashore (PORE), Golden Gate National Recreation (GOGA). The network has identified vital signs, indicators of ecosystem health, which represent a broad suite of ecological phenomena operating across multiple temporal and spatial scales. Freshwater quality ranks among the most important vital signs being monitored by the SFAN. The SFAN has many unique aquatic resources that are significant in an ecological and economic context, supporting a variety of federally protected species. Furthermore, the National Park Service (NPS) has a legal obligation to ensure streams meet minimum water quality standards. Monitoring methods followed the approved SFAN freshwater quality monitoring protocol (Cooprider and Carson 2006). Sampling includes collection of field and lab measured water quality parameters. Core parameters measured in the field include temperature (air and water), dissolved oxygen, pH, specific conductance, and discharge. Pathogen parameters include coliform bacteria (total coliform and Escherichia coli (E. coli)) as well as fecal coliform in Olema Creek. Measured nutrient parameters include nitrate, ammonia and total Kjeldahl nitrogen (TKN). In Water Year 2007, a total of 255 visits were made to 25 monitoring stations throughout four national park units. Monitoring sites were visited monthly. In addition, on Olema Creek, staff conducted weekly sampling during an intensive five-week winter sampling season in cooperation with the San Francisco Regional Water Quality Control Board Tomales Bay Total Maximum Daily Load pathogen monitoring program.
