I don't know what day the main Eastern Sierra opener is, but before the opener your options are somewhat limited. Tomorrow ( March 2nd) they will open Pleasant Valley, the Lower Owens, Diaz Lake and the various creeks around Bishop. Every year WON hypes up this Diaz Lake for the southern opener but don't fall for it. I fished it once with Jamon and it is a shallow mud hole way down the valley from Bishop. They load it up with planters for the southern opener but when we went the fishing was just plain bad because the water visibility was about 6 inches. I'd go up to Pleasant Valley and throw Kastmasters or Thomas Bouyants. Mix in the Pins Minnow for the browns and then when you get bored of that, hit the various roadside access spots on the lower owens for a shot at some scrappy browns and the occasional alpers.
