Here is my e-reply report to an inquiry from a fella in Chicago who wanted to do some golfing & fly fishing (...and escape the heat in the mid-west) in the area:
"The Truckee River is lowering but still too warm...AM fly fishing is best. The Little Truckee is rising (releases from the dam)...few fish rising and few bugs emerging...so there is limited dry fly fishing. Most productive fly fishing on both rivers is indicator nymphing.
Best possibility of consistent dry fly angling is on the North Fork of the Yuba; an hour north of Truckee. It is a beautiful mountain, freestone stream. The stream-bred rainbows are smallish; 6"-11".
The weather in the Tahoe area has been in the 75-85 range with clear skies and at times gusty winds. These conditions are forecasted for minimally the next week. We’re awaiting cooler nights as a precursor to the start of Fall…hence cooler water temps and less crowds."
