The FFC studied fish habitat of the lower Cosumnes River floodplain in cooperation with the Nature Conservancy and UC Davis. The study was funded under a CALFED grant to determine the effects of expanding the lower river floodplain by breaching levees and allowing high spring flows to once again reach lower river terraces. FFC staff monitored fish use of the newly breached floodplain via beach seines, fyke netting, light traps and electro fishing.
