§ 697. Examples of Amounts Considered Reasonably Necessary.
Currentness
The amount of water considered reasonably necessary for certain uses when the appropriation will be by direct diversion shall be determined in the following manner:
(a) Irrigation Use.
(1) In most portions of the central valley of California and elsewhere in the State where similar conditions prevail a duty of one cubic foot per second continuous flow to each 80 acres shall be considered a reasonable headgate duty for most crops. Where there is a greater abundance of water and a heavy transportation loss, or the land to be irrigated is of a porous, sandy or gavelly character a continuous flow allowance of one cubic foot per second to each 50 acres may be considered reasonable. Under other conditions where water supply is less abundant and conditions are favorable to a more economical use a duty of one cubic foot per second to 150 acres may be considered reasonable for most crops. For the irrigation of rice the customary allowance shall be one cubic foot per second continuous flow to each 40 acres of irrigated land.
(2) The equivalent of these continuous flow allowances for any 30--day period may be diverted in a lesser time at a greater rate so long as there is no interference with other users, and a clause allowing such rotation will be included in a permit issued for irrigation purposes.
(b) Domestic Use. Allowances for domestic use are variable, depending upon the character of the place of use, method of use, character of use and availability of water. The quantities considered reasonable for the respective domestic uses are as follows:
