Provisional Flow Guides <br /> Table 1 <br /> Summary of Provisional Flow Guides <br /> (average streamflow(cfs)at the Kremmling,CO streamgage) <br /> Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug Sep <br /> Dry Years 400 400 400 400 400 400 600 600 600 600 600 600 <br /> Average Years 600 600 550 500 500 600 800 1,350 1,350 1,100 950 900 <br /> Wet Years 700 700 700 700 700 900 1,600 3,500 4,500 2,800 1,500 900 <br /> Notes: <br /> Dry year flow guides are based upon Grand County Stream Management Plan(GCSMP)critical flows. <br /> Average year flow guides are based upon current data that Includes a combination of GCSMP fish flows and acceptable levels of floatboating flows. <br /> Wet year flow guides are based upon current data that Includes preferred recreation boating flows and historical hydrology. <br /> Wet year flow guides also include flushing flows recommended in the GCSMP(1800 cfs for 3 days,1 in every 2 years). <br /> Provisional Water Quality Guides <br /> [SC needs to determine comfort le ei with tA`C.aCt <br /> ouailt\ at'indarus for dretection ofagi,Litit; life, and Iecieat'i;?nal uses <br /> is i"1'ov;s:(..+rtal Guides. ! hose inctuilt:' Lt.in „-, i?`i:'t(:S l}i <br /> Provisional Temperature Guides <br /> Other Provisional Guides? <br /> b. Basis for Provisional Flow Guides <br /> Provisional Flow Guides are established by the type of hydrologic year: <br /> dry, average or wet (see Figure 2). Initial prediction of a given hydrologic <br /> year.•:,.,;i re made in [month`'] and will be based on the April to July "Most <br /> Probable"forecast of streamflows from the Colorado Basin River Forecast <br /> Center for the Kremmling gage. In early summer <br /> + ,;, .>,. .1 t'"0.0,(Mt.I',';ri, the initial prediction will be adjusted based on <br /> actual flows at Kremmling. That adjustment may result in re-defining the <br /> type of hydrologic year and thus the management approach. <br /> The prediction of type of hydrologic year is used to define whether a wet, <br /> average or dry hydrologic year is in progress in a given year, and the <br /> appropriate management considerations to put into play. For example, <br /> dry year management may be focused on protecting the survival of fish <br /> rather than focusing on an optimal recreational boating experience; <br /> Page 6of16 <br />
