Those small changes in flow out of Palisades Dam made recently have no impact on fishing. But the water coming out of the reservoir remains a bit colder than normal for the time of year. That could be part of the reason for nymph fishing in the riffles currently being more successful that dry fly fishing. The warmest weeks of summer are here and will be present until mid August, so look for dry fly fishing in the riffles to improve soon. This is also the time of year when courtesy is important. Certainly the river is crowded. Embarking and disembarking boats can require courtesy and patience to minimize problems. There are plenty of riffles and gravel bars to visit (see the above pic taken when flow at Lorenzo is about 5500 cfs) , so if one of these you like is occupied you surely can find a vacant one downstream.
