On the 20,000 .s.; the latter believed that the average annual spring-flood discharge might be of the order of 75,000 In Anon. (1941, p. 46) it is stated: "With the river regulated by Boulder Dam the steady flow ranges from 12,000 to 20,000 cubic feet per second. The maximum flow to be expected is about 45,000 cubic feet per second, to control the usual seasonal floods. This may reach 75,000 cubic feet per second once in about 100 ; (It should be noted that, as far as practical, an even rate of flow is desirable for flood control, power production, and the diversion of water for irrigation and into the Colorado River Aqueduct.) A second control is possible at Parker Dam through the alternate impoundment and release of water. However, Lake Havasu 's potential regulatory power is minimized by the 10-foot limit to the variation in its water level already mentioned as necessary for efficient pumping into the Aqueduct. The other dams below here can not be considered regu- latory as they do not enclose large storage reservoirs. While its flow has been stabilized to a great extent, the Colorado is still not tamed, and plans exist for further regulation. The projected Davis Dam at Bullshead about 67 miles below Boulder, which would back the water up close to the foot of the latter dam, is designed to minimize the effects of large releases from Lake Mead for power in excess of irrigation requirements. Flood control dams are contemplated for the Williams River, at the Alamo site, and at the Sentinel site on the Gila, which already has some flood protection. Regulation of its flow can mean that there will
