California:
The Water master has turned down the flows out of Boca, Donner and Prosser Reservoirs and more water is coming out of Lake Tahoe. Tahoe is the only Reservoir out of the 4 that the water comes off the top. What this means is the water in the Truckee is warmer overall. This enhances the need to fish in the mornings and evenings.

Dead Drifting Crawfish patterns and golden Stoneflies with a smaller dropper like a Caddis or a Little Yellow Stone for nymphing is a good way to go. Use enough weight to get your flies down to the fish. You should start to see some fish in faster water where there is more oxygen. There are still some Caddis and Little Yellow Stones hatching in the evenings as well.

Nevada:
The flows are about normal for this time of year. NDOW is stocking all the parks every two weeks or so and the fishing has been great. There have been some big wild Browns and Rainbows caught along with the thousands of planted Rainbows over the past few weeks. Nymphing in the mornings before the tubers get going has been working well. Try a smaller Stonefly with a Prince Nymph dropper. There have been some sporadic Caddis hatches in the evenings but it is very short right at dark.

Flows on the Truckee:
Truckee 273 CFS
Boca Bridge 552 CFS
Farad 613 CFS
Mogul 460 CFS
Reno 509 CFS.
