As outside temperatures warm in March, trout metabolism increases: during a typical March, fish will be active earlier in the morning and later in the afternoon than February and January. Midges (standard patterns and specialty ties, sizes #20-#28, assorted colors), bwo, and black stonefly hatches continue, but the key addition to the mix is sucker spawn: this packet of protein is a favorite of every living thing in the stream. Nymph fishing continues to be largely stable regardless of outside temperature: our spring-fed limestone beds are consistently 50-52 °F, cool during the summer and warm during the winter. Although BWO and stonefly hatches can be quite heavy on Penns Creek, fish rarely rise for them; it's generally agreed that Penns is so rich subsurface that fish don't need to waste energy rising to eat bugs at the surface. Spring Creek continues to offer the best dry fly fishing of the winter, with the best of the bwo hatches in February and some excellent black stonefly hatches in recent years (the removal of McCoy's Dam in Milesburg has improved hatch conditions radically). Although Big Fishing Creek gets good BWO and stonefly hatches, the best dry fly fishing is still midges. Pennsylvania is open year round to catch-and-release.
