    Clear Lake Winter Levels
    
    
    The Gopcevic Decree required the development of an operation schedule for the Clear Lake Dam on Cache Creek. Yolo County Flood Control and Water Conservation District must operate the Clear Lake Dam in accordance with the schedule. The Operation Schedule identifies lake levels for different times during the winter to which Clear Lake is allowed to fill. Selected dates and corresponding lake levels are:
    Prior to January 8 	5.50 Rumsey
    January 16 	5.96 Rumsey
    January 19 	6.08 Rumsey
    January 24 	6.27 Rumsey
    February 14 	7.10 Rumsey
    March 15 	7.56 Rumsey
    
    When the actual lake level is below the level indicated in the schedule, no water is allowed to be released at the dam. Should the actual lake level rise above the level indicated in the schedule, the gates in the dam must be opened to lower the lake level. As the actual lake level approaches the level indicated in the schedule for that date, conditions are taken into account so that the dam operation will minimize flooding, while allowing the lake to fill to 7.56 Rumsey. There are two exceptions. When the lake is filling rapidly, water may be released from the dam when the actual lake level is within one-half foot below the level indicated in the schedule. When the lake is falling and no rain is anticipated, the dam may be closed when the actual lake level is within one-half foot above the level indicated in the schedule.

    Releases may take place when the lake level rises above the scedule.
    
    


    Exception No. 1: When the lake level is a few tenths, not more than five, below the schedule, and rains occur of sufficient intensity to indicate a sharp rise in the lake level, then such a rise should be anticipated and the gates opened. Exception No. 2: When the lake level is a few tenths, not more than five, above the scedule, and it appears that under to conditions existing at the time, the lake level will join the schedule elevation in a few days, then the gates should be closed.
