Flow out of Island Park Dam was dropped to 1310 cfs from near 1700 cfs yesterday. This means easier wading in the river at Box Canyon, Last Chance-Harriman-Riverside and below, but more of a tendency for the river to warm a bit. Early AM spinner falls and later in the day flav and caddis activity still interest fish, but terrestrial insects are coming on. Try fishing during these times for another reason—–fewer visitors. Frequent thundershowers have helped cool things off during evenings.
Flow out of Ashton Dam has dropped a bit (2600 cfs to 2300 cfs) and is subject to irrigation demands. Fishing between here and Chester Dam remains fair with best times for action being early and late in the day. Don’t overlook using terrestrial insect patterns when you visit the river; here and anywhere else.
