The Sacramento River floods of 1969-70 led to degradation of the riverbed at the head of the Glenn-Colusa Irrigation District GCID intake channel. The elevation of the riverbed has dropped about 3 feet, causing problems with operation of their fish screens, intake channel, and pumps. The proposed GCID project will restore the river gradient to its pre-1970 level, improve fish screen operations, and improve intake channel conditions. Project alternatives consider rehabilitating existing facilities, constructing new facilities at the existing site, and constructing new facilities at new sites. GCID has submitted a project report for Corps review and analysis. The GCID Report advocates 3 project alternatives, each including a gradient restoration feature of 5 sheet-pile weirs. The Corps was asked to participate in the gradient restoration feature only.
