  • Ventura County
    Steelhead/rainbow trout resources of Ventura County Rincon Rincon Creek consists of about 9.7 stream miles. It flows southwest, entering the Pacific Ocean at Rincon Point. The culvert at the Highway 101 crossing is a total passage barrier (Stoecker et al. 2002). A watershed plan prepared for Rincon Creek includes a review of historical steelhead information. The review notes O. mykiss stocking occurred in the 1940s and subsequently. Anecdotal accounts of trout observations from the 1950s to the 1980s also are included (Tetra Tech 2007; Stoecker et al. 2002). Rincon Creek was surveyed in 1993 and no fish were observed. The survey report states, “Sediment inputs from Casitas Creek are destroying downstream habitat” (Unknown 1993). A 1994 DFG memo relayed the results of surveys from that year. The memo states, “The Wheeler Fire [in 1985] could have been the event that eradicated rainbow trout from Rincon Creek, although there is anecdotal information from a landowner along Rincon Creek that suggests that the population was extirpated as early as the 1960’s” (DFG 1994a). The memo adds, “It appears that the Highway 101 culvert has prevented the recolonization of rainbow trout/steelhead in Rincon Creek” (DFG 1994a). Consultants surveyed Rincon Creek as part of a steelhead study, and observed O. mykiss likely representing one year class in 2001 (Stoecker et al. 2002). A 2002 memo from NMFS staff states, “Rincon Creek provides approximately 4 miles of steelhead spawning and rearing habitat…” (NMFS 2002a). A 2002 study report notes water quality impacts on Rincon Creek from the large sediment load carried by Casitas Creek, a tributary (Stoecker et al.

    Case Study: Ojai Valley Land Conservancy Watershed: Ventura River Watershed Researchers: Kaily Bourg and Lauren Miller Year Grant Program Project Title Watershed Award Amount 2010-2014 DOC Watershed Watershed Coordination for the Ventura River $277,446 Program Ventura River Watershed 2014 DOC Watershed Drought Emergency Response Ventura River $3,397.84 Program Extension This case study involves an assessment of a single coordinator grant received by the Ojai Valley Land Conservancy. Findings of this research are based on interviews with stakeholders involved and a review of documents associated with the grants. Overview The Ojai Valley Land Conservancy (OVLC) received a Department of Conservation Watershed Coordinator Grant in 2011 on behalf of the Ventura River Watershed Council and hosted the position during the three-year grant period. The watershed coordinator grant was extended by six months in 2014 as part of the grant program’s Drought Emergency Response Extension. OVLC is a nonprofit land protection organization supported by private donations and is an active member of the Ventura River Watershed Council leadership committee. The Council maintains a balanced and diverse leadership committee with stakeholder representation from government, water and sanitary, land management and recreation, environmental, and business and landowner entities. See Appendix A for list of current participants. Following the Department of Conservation grant period, a collection of stakeholders extended financial resources to support a part-time coordinator position for the Ventura River watershed. For the first few years following the grant, the position was contracted and housed by the Ventura County Watershed Protection District. The position is currently housed at the Casitas Municipal Water District.
