FORTY-FIRST BIENNIAL REPORT 47 range and large scale program the mechanics of operation have been slow of achievement. The engineering help necessary for the drawing np of plans for large projects is now more readily available than when the Wildlife Board first began to make allocations of fnnds. Detailed plans have bcH^n completed for the constrnction of two fish ladders on the Dagnerre Point Dam on the Ynba River. This location is abont 10 miles above Marysville. Plans also have jnst been finished for the constrnction of a fishway on the Sutter-Bntte Dam on the Feather River. This dam is located abont 10 miles below Figure !t. Mill Creek electric fish screen The fish screen sliowii in Figui-c !) has been bnilt at tlie heading of the Los Molinos Water Company on Mill Creek. This site was chosen because of its suitability for f nrther experimentation on electrical screen- ing. EU'ctric fish stops so far have not been very snccessful. This screen incorporates several new ideas in its constrnction and hope is held that a trnly etfective electric screen may yet be produced. Four small wooden fish ladders were installed in gravel diversion dams along the Pierced Kiver. Their efi:'ectiveness has been donbtfnl dne to lack of water at the proper time. This lack of water during the salmon run is not so much due to lack of runoff' as to the mismanagement of this fiow. Almost the total flow of the river is imj^ounded early in the salmon season often allowing sections of the stream bed to dry up. Later when the dam is full, a larger spill occurs w'hich is often damaging to both small diversion dams and their fish ladders. A more extended period of water release would make a great difference in the salmon production potential of the Merced River. The Division of Fish and Game has worked closely with the U.
