Of course, the fishing isn't always that hot when winter is melting into spring, but spending some time doing early-season scouting gives you a head start. The more fishing you do in less than ideal conditions, the more you'll learn about trout and about your own region, and that will make you a better fisherman. In every area where trout live, there are a few good early-season bets. Spring creeks have more uniform water temperatures, so they'll probably be open and fishable sooner than the surrounding freestone streams. The same goes for tailwaters, since streams fed by bottom-draw dams function as artificial spring creeks. Early fishing in spring creeks and tailwaters can involve a lot of nymphing, but hatches sometimes come off ahead of schedule in the warmer water, especially those of small aquatic insects like midges and the miniature, drab mayflies that flyfishermen call bluewing olives.
