Regular trout anglers do well by trolling during early morning hours with pop gear and worm. Ice forms and then melts with the warmer afternoon temps. Not advised to try and ice fish yet. Nobody has really been seen trying to fish the lake for the last two weeks. Lake is ice-free but few anglers are using the reservoir.
Boat ramps are open and ice free.
Remember that you should plan on paying a fee to fish from shore. Yuba State Park has five areas that they allow people to fish from shore. The rest of the reservoir shoreline is either closed to fishing or is private property. There is one small stretch of shoreline, from the main state park on the west side of the reservoir, to the bridge that crosses the reservoir, that you can fish without paying a fee. Very little fishing pressure.
