Inadequate flows do not provide necessary physical habitat for <br />fish. <br />2~ High flows making wading dangerous. <br /> <br />Minimum Flow: <br />Maximum flow: <br />Optimum flow: <br /> <br />Other info: <br /> <br />50 cfs year round <br />450 cfs <br />200 cfs year round <br />Basis: information provided by Dale K. Fields, Summit Guides <br /> <br />The SEIS required boulder placement for habitat improvement as a <br />mitigation measure below Williams Fork Reservoir4 <br /> <br />Other Areas of Concern: <br /> <br />Stream Reach: South Fork Ranch Creek <br />Other: Brook trout access into lower reaches of Colorado River Cutthroat <br />inhabitated areas is creating problems for ongoing attempts to stabilize and enhance <br />cutthroat populations.
