Montana fishing is pretty much all about time. In the summer, you can set your watch by the trio hatch that starts just about 9:30 every morning. Forty-five minutes later, it’s the spinner fall. Although you can depend on size #18-#20 tricos working well, you’ll also find that a #12 Royal Wulff with a #16-#18 bedhead pheasant tail nymph makes a deadly combination as well.
After lunch, it’s hard to beat a #12 Jay-Dave’s Hopper – and if you haven’t fished a hopper on a hot Montana afternoon, you’re in for something special. Caddis hatch sporadically all day long, but you’ll find the fishing best just after dinner, just before dark. For bigger water, it’s much the same with the addition of big streamers and stonefly nymphs to attract those football-sized Madison River browns.
