Putah Creek - Winter Park Percolation Dam Removal - Winters, CA Projects along Putah Creek, near Winters, CA are ongoing with the Lower Putah Creek Coordinating Committee in the lead. StreamWise works with LPCCC and the Solano County Water Agency to address resource issues along Putah Creek and several tributaries. Proposed projects include removal of the large concrete percolation dam near the center of Winters Park. To enhance this project, StreamWise has recommended that a floodplain elevation bench be constructed for access to the site, and for subsequent use as floodplain surface for Putah Creek. By constructing a floodplain elevation bench, the over-widened pool in this reach could be narrowed, enhancing flow velocity and habitat features. This concept is one that has been utilized at several sites along Putah Creek with good success. By increasing the floodplain width, the channel is better able to dissipate the energy of flood flows without damage to the channel. Riparian vegetation recovery offers additional benefits to riparian obligate species. Creation of the floodplain surface also allows for recreational access to the stream edge with Winters Putah Creek Park as the hub. The dam removal project is scheduled for summer of 2009.
