<br />The....on Clear Creek (period of record 1946 - 1995; drainage area of 67,1 square
<br />miles; elevation at 8,885 feet) indicates that the year-round existing CWCB instream
<br />flow of 15.0 cfs is met 95% of the time or more during the summer, but, only around
<br />25% of the time during the winter. The winter range is from 5 to 35 cfs averaging
<br />around 15 cfs, The low portion of the USFS high flow range (346,0 cfs) is met 1 % of
<br />the time in May, 20% of the time in June and 10% of the time in July, The high portion
<br />of the USFS high flow range (594,0 cfs) is met 0% of the time in May, 5% of the time in j
<br />June and 1% of the time in July,

<br />North Cottonwood Creek
<br />QP at sec 9 - 14S - 79W; 100 feet upstream of the east section line (forest boundary)
<br />Amount: The existing CWCB flow recommendation for a base flow of 7.0 cfs year-
<br />round is acceptable and needed for fish survival at the QP,
<br />
<br />There is no .-.on North Cottonwood Creek.

<br />A new QP was located at sec 24 - 14S - 80W; just above confluence with Huges Creek
<br />Amount: The QP will be moved upstream above the lake to help water users. The
<br />existing CWCB base flow of 10 cfsyear-round is acceptable and needed for fish
<br />purposes, The USFS requests a bi"h fin", for 20 days between May I and July 15 of at
<br />least 70% of bankfull and up to 120 % of bankfull (quantified as 110,0 cfs to 188,0 cfs)
<br />to transport heavy sediment loads caused by natural erosion, and to maintain channel '
<br />capacity, geometry, and aquatic habitat in this alluvial stream, The Group wanted this
<br />definition (limits) of the high flow request and assurance that there would be some
<br />upstream exchange potential particularly during runoff,
