Welcome to the board pen! The L.O. is open year round from Crowley dam to Owens Lake, there is a special regs section downstream from Pleasant Valley Reservoir to Five Bridges. Upper O is also open as is Hot Creek, but single barbless CNR only. PVR is good for tubing and lure casting.
Camp at PVR, right on the L.O., or comfy digs in Bishop. Check DFG regs book for particulars on boundaries. milt.
