Caption: The chart shows the number of juvenile steelhead per 30 meter reach of stream provided by the Marin Municipal Water District (MMWD) for the Lagunitas Creek watershed for some years from 1970-2000. Surveys in 1970, 1980, 1982-1988, and 1990 were conducted by the California Department of Fish and Game and separate topics provide more data on these surveys. Values reported in this topic differ from the 1982-1986 CDFG-abundance topics because different numbers of sites were used to calculate average abundances in order to allow for more valid comparison among years and varying sampling methods. The more recent data were collected by MMWD or their contractors and the National Park Service. No surveys of this kind were conducted in 1971-79, 1981, 1989, 1991, and 1992.
