Okay. In the interest of goodwill to man, etc., I'll share some of my secrets. The place to fish is the Platte River, directly below the Chatfield dam. I've used 3 techniques with success: 1) A wad of cube steak between golfball and billard ball in size, fished in the still water to the sides of the tail races. The larger size will keep the crawfish from dragging your bait into the rocks. 2) Stand on the tail races and cast a whole night crawler (use a worm threader) below a single split shot upstream into the tunnel and let it drift downstream. This will produce Walleye, trout and suckers as well. 3) Fish from the platform directly over the tunnel. Rig a single heavy (1oz or heavier) weight with a snelled hook about a foot above the weight. Use the crawler/worm threader rig and drop it right below the white water. This is also good for Walleye, trout and suckers.
I've never used stink bait, so I don't know if that works, but there are a lot of cats in there getting fat on crawfish and dead stuff churned up in the tunnel. I've seen guys catching all types of fish on live minnows, too.
NOTE: Anytime you catch a fish with any size from the tail races, you'll have to walk the fish down to the end, then back around to the still water. It helps to have a buddy to help land the fish. Once you get there, you'll see what I'm talking about. My brother in law caught a 18" walleye there once and just hoisted it 30' straight out of the water, but I wouldn't recommend it.
