<br />Problem Identified: 1. Low flow temperatures are high enough to stress fish and <br />chronic and even acute impacts occur. <br />2t Inadequate flows do not provide necessary physical habitat for <br />fish. <br />3. Whirling disease <br /> <br />Minimum Flow: <br /> <br />Optimum Flows: <br /> <br />Other Info: <br /> <br />125 cfs (year-round)** <br /> <br />200 cfs (year round)** <br /> <br />Basis: Barry Nehring's CDOW P...51 (7/88) report recommends a <br />125 cfs minimum and 200 cfs optimum flow for juvenile and adult <br />brown trout at Hot Sulphur Springs. <br /> <br />Nehring also recommends rainbow trout optimum flows at Hot <br />Sulphur Springs as follows: 4/20-6/15 300 efs; 6/15...7/15 125 efs; <br />7/15-10/15 175 cfs; 200 cfs year-round for adults. This may be <br />useful relative to Whirling disease. Temperature in this stretch is a <br />serious issue. <br /> <br />In June of 2001, George Stark took a temperature reading of 80 <br />degrees at lOAM. There were dead fish on the banks. <br /> <br />Stream Reach: <br /> <br />~-~~~~~~~----------------~~~~~---~-~--~~~~-----------~~~-~--------------~~~-~-~-~-~~~---------------~~---~-~ <br /> <br />Fraser River below Vasquez Creek <br /> <br />Problem Identified: 1. Inadequate flows do not provide necessary physical habitat for <br />fish. <br /> <br />Minimum Flow: <br /> <br />Optimum Flow: <br /> <br />Other Info: <br /> <br />8-10 cfs (year-round)* <br />Basis: Denver Water's Systemwide Environmental Impact <br />Statement. I'm not clear on the rationale, but think the 8 efs is <br />based on IFIM. Current CWCB ISF is 8 cfs (5/15 - 9/15) and 3.5 <br />efs (9/16 ~ 5/14). <br /> <br />11 cfs <br />Basis: Denver Water's Systemwide Environmental Impact <br />Statement which suggested directing 3 cfs from Williams Fork <br />during fall/winter to bring flows up to 11 efs (29 cfs at Granby <br />gage)~ <br /> <br />The SEIS also recommended livestock fencing along the Fraser <br />between Fraser and Tabemash as aquatic life mitigation~ <br /> <br />~~---------------~-~-~--~~~--------------~-~~~-~-~~-~~~~~-~-~----------------~~---~~~------------~~~-~-~~--- <br />
