The sun is out! The Birds are out! The BWO’S are all over . This hatch is one of the first for the mayflies and always brings the fish up. Beware! The fish that are up on this hatch are generally smaller in size but it provides a great opportunity to get the rust off those casting skills. The larger fish are still in deeper or faster pockets, so use split shot and get to the bottom for these fish. The hatch begins about Noon and lasts till about 3. Olive, mahogany and chocolate patterns in sizes 16,18 and 20 will all work for this hatch.
