Major fish passage barriers within the Santa Ynez River watershed. and oak woodland, with lowland areas now used for agricultural, residential, or recreational activities. The river empties into the Pacific Ocean north of Point Conception near the city of Lompoc. As early as the late 1800s the Santa Ynez River and its lower tributaries, such as San Miguelito and Salsipuedes Creeks, provided a steelhead and rainbow trout recreational fishery (Lompoc Record 1875a, 1875b, 1875c, 1875d, 1875e, 1875f, 1880, 1890a, 1890b, 1891a, 1891b. 1891c, 1892, 1893a. 1893b. 1893c, 1894a; Lompoc Centennial Committee 1974; Barker 1979; see also Bowers 2008 for additional newspaper accounts of steelhead and rainbow trout in the Santa Ynez River). Use of this fishery grew in the early 1900s, following completion of the coastal railroad between San Francisco and Los Angeles in 1901, and the subsequent extension of a spur into Lompoc (Lompoc Record 1908a, 1908b, 1908c, 1908d, 1914; Mears 1947; Kreider 1948; Tompkins 1974; Palmer 1999; Jacoby and Ward 2009). Santa Ynez River steelhead attracted anglers from around southern California and brought considerable benefits to the local economy. Beginning in 1920, a series of large dams were built along the Santa Ynez River: Gibraltar Dam, built by the City of Santa Barbara in 1920, Juncal Dam impounding Jameson Reservoir, built by the Montecito Water Distri
