Water Usage

01. Incidental Stock Water. A water user holding a water right authorizing irrigation use, but not stock water use, may divert a portion of the quantity described for irrigation use to maintain a reasonable water supply for stock water use. This stock water use needs to utilize the same point of diversion, place of use, and season of use for the irrigation use on the water right. (7-1-26) 02. Winter (Non-Irrigation Season) Stock Water. During the non-irrigation season, from October 16 through April 30 except as modified by Rule 040.04, the storage of water in Mackay Reservoir is superior to all rights from the Big Lost River with points of diversion downstream from Mackay Dam, subject to minimum release. (3-31-22) a. Water users holding water rights authorizing winter stock water use may call for the delivery of the IDAHO ADMINISTRATIVE CODE IDAPA 37.03.12 Department of Water Resources Water Distribution Rules – Water District 34 Section 060 Page 8 water rights provided that the delivery does not interfere with storage in Mackay Reservoir. (7-1-26) b. A water user calling for delivery of winter stock water must have access to a diversion point and delivery system to convey the right to the place of use recorded in the water right. If the headgate and delivery system are controlled by an entity other than the water user, the watermaster will only deliver the water with the concurrence of the owner of the headgate and delivery system and then only when such delivery does not constitute unreasonable waste as determined by the Director.
