CWCB recommended Base flow-Kremmling to Pumphouse. Flows measured at USGS near <br /> Kremmling(cfs): <br /> Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec <br /> Flow 400 400 400 600 600 600 600 600 _ 600 400 400 400 <br /> Optimal target flows in a dy year(defined pursuant to runoff estimates where the expected <br /> runoff is expected to be 70%of average or less based on a 10?year running average)(We need <br /> to compare these numbers to the 70%of average numbers- <br /> Pumphouse to State Bridge. Flows measured at USGS near Kremmling(cfs): <br /> Jan Feb Mar Apr May Jun Jul Aug_ Sep Oct Nov Dec <br /> Flow 400 400 400 600 - - - - 400 400 400 400 <br /> 600- 600- 600- 600- <br /> 900 900 900 900 <br /> This target flow scenario also includes a target flushing flow 1 out of every 2 years for up to <br /> 1800 cfs. Between May and August,the target flows are a range from 600 cfs to 900 cfs. The <br /> SG could, (in my opinion)see if they can commit to a certain volume that would be dedicated <br /> in dry years to the optimal target flows. The SG could attempt to work with existing water rights <br /> holders to see if they can commit to meeting existing water right needs by shaping <br /> a certain volume that could be dedicated to the optimal target flows. Thus, if <br /> the previous year was a dry year and no flushing flow was met,then the SG management <br /> committee can elect to reshape the flows in May through August to allow a Flushing Flow of <br /> 1800 cfs or greater for a 3-day duration during the May to mid-June period. However,this <br /> would have to be managed in a manner to respect the prior appropriation system. <br /> *Recreation(Fishing)ORV Flow Ranges are based on Grand County Stream Management Plan,Phase 2 <br /> (Tetratech et al.,April 2008)augmented by CDOW fish surveys utilizing the"mark and recapture" <br /> method conducted[fall, 2008] and by user surveys conducted by Vital Resources on ,2008.# <br /> Flushing Flows are based on Grand County Stream Management Plan,Phase 2(Tetratech et al.,April <br /> 2008) <br /> Page 12 of 15 <br />
