## Abstract

This rule adjusts the 1988 Operating Criteria and Procedures (OCAP) for the Newlands Irrigation Project (Project). Adjustments are made to the Project efficiency requirements, maximum allowable diversion calculations, and Lahontan Reservoir storage targets in the 1988 OCAP to reflect current irrigated acreage, court decrees which have lowered the water duty applicable to certain Project lands, and other factors affecting water demand. To better manage diversions from the Truckee River to the Project, the rule provides flexibility to adjust the water supply in response to Project demand, flexibility in using snowpack and runoff forecasts, and extends the time frame for storing water in Truckee River reservoirs in lieu of diversions to the Project from the Truckee River.
