I must be doing something wrong. My wife & I have drifed minnows all over the lake 3 times this month. Caught one smalley by the dam. We have had some success trolling sparkel tails for trout, but no walleyes. I am not marking many fish in that shallow of water, mostly in 30 -50 ft and suspended around 12 - 20 foot for active fish.
I fished earlier in the day and only got one small smallie. The key seemed to be drifting very slowly, which I couldn't do until the wind died down. I have since invested in a drift sock.
Also, I think it's hard to rely on electronics to see fish near the bottom in shallow water...the boats spooks them maybe. I just find good feeding habitat, fish during low light conditions, and go slow.
Smallies that crawl ? Thats proof right there what the water from Rocky Flats does to the life in that lake...LOL...just kidding paddlefish, couldn't resist that one!!
btw nice fish dtromp , keep it up!!!
