Not the day for it
River high but settled. Not much stacked in your favour today. Worth an hour if you are nearby, not worth the special trip.

A dam sets this river's temperature, not the weather, so it can shift several degrees within hours when the release changes. Measured at the gauge. It also warms as it runs away from the dam.

How to fish it · for Rainbow Trout

Where

Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.

What's coming
Plan ahead
5-day outlook
Water here at 22.2°C. Nothing cooler within range.
Conservation note

Rainbows are stocked. Brown trout are covered by the regulations (one over 20 inches), but ODWC's stocking list names rainbows only, so their current presence is unconfirmed and they are not scored. Not wild. The tailwater is also managed for striped bass, which are not scored.
