I spent Friday fishing a new (to me) local lake. Hit the water at 10am, kicked over to a 100 yard long bank of cattails and found a nice weedy flat that slowly dropped off from 4-15’. Not much bug activity so I started off casting an olive bugger on a clear intermediate line. After 4-5 casts, hooked a big fish that jumped four times then screamed off to deep water and spit my bugger. Another 45 min of casting over the weeds produced nothing so I moved on to a steep bank with fallen trees along the edge. Looked like classic brown trout habitat so I worked the edges of the trees with my bugger and managed one nice 16” brown. Another 30 min of casting to the trees produced nothing. By now it was after noon and a chironomid hatch was getting started. I had a floating line rigged on my second rod so I started off with a micro leech and black snowcone dropper at the color change, about 12’. Nothing. Moved shallower. Nothing. Still loads of midges popping. Pulled the intermediate line off and put on the type 6 full sink. Rigged up a 4’ 4x leader with a #12 Ira’s Deep Chironomid with #14 black snowcone dropper. Moved out to the area where the most bugs were popping and clipped a weight to the bottom fly. Measured the depth at about 30’. Cast out just enough line to be within inches of the bottom and waited a full minute for my rig to sink. Before I could start my retrieve, Fish On! It went like that for about an hour. I landed 8, lost 3-4 others. All rainbows 16-19”. Two showed me my backing. Then nothing. Like a freakin’ light switch. I fished another 2 hours without a bite and called it a day.
