Document Description
The Water Agency is filing a temporary urgency change petition requesting that the SWRCB make the following changes in the minimum instream flow requirements for the Russian River mainstream that are specified in Decision 1610 and the Water Agency's water right permits: (a) a minimum instream flow of 50 cubic feet per seconds (cfs) in the Upper Russian River from its confluence with the East Fork to its confluence with Dry Creek, and (b) a minimum instream flow of 60 cfs in the Lower Russian River downstream of its confluence with Dry Creek to the Pacific Ocean (Figure 2). These changes are 25 cfs reductions from the current Dry condition minimum instream flow requirements in teh Upper and Lower Russian River under Decision 1610. To allow the Water Agency to optimally manage flows in the Upper and Lower Russian River. The Water Agency is requesting that the TUCP minimum instream flow requirements be specified as 5-day running averages of the specified minimum average daily stream flows with the conditions that instantaneous flows in the Upper Russian River are never less than 40 cfs and instantaneous flows in the Lower Russian River are never less than 50 cfs.
