No person shall operate any motorboat or other motor-powered vessel at a speed in excess of five miles per hour relative to the stream bottom for upstream speeds and relative to the water surface for downstream speeds on that part of the waters of the American River from the Interstate 80 bridge east to the Nimbus Dam; provided, however, that no motorboats shall operate on that portion of the American River which is closed to fishing during any given year by action of the California Fish and Game Commission because of the salmon spawning period. This prohibition against motorboats shall commence each year concurrently with the commencement of the fishing ban imposed by the California Fish and Game Commission and shall continue in effect until March 15th of each year.
