I just posted one for Dillon but thought you might have a "notify me of response" set up ... so here it is ...
I just got back from Dillon.
I spent about 6 hours in the morning nearly every day trolling around Dillon.
I never did get all the way over to the Blue River inlet because a storm blew in and I have only a 15 HP motor and was afraid I wouldn't make it back to the marina.
Anyway, I marked a lot of fish but only was able to land small ones. I had not fished Dillon for years but wanted to escape the heat in Denver. It was nice and cool; about 25°F cooler than Denver (meaning 78°F instead of 103°F).
I mostly used one of my favorite lake trout rigs ? a small pop-gear made of 3/4" hammered nickel willow-leaf blades with a needle fish (fluorescent rainbow colored) attached to a trailing leader. I got down deep by attaching a 1.5 oz bell sinker just in front of the pop gear rudder.
I caught rainbows, lake trout, brown trout, and salmon on this rig. The trout were caught along the face of the dam trolling in 13 to 48 feet of water (deeper later in the day). I caught the salmon trolling across the sandbar on the NE edge of the outlet basin (about 20 yards out from the buoys by the bowel) on the west end of the dam. I marked a lot of fish by the outlet bowel, some large, and I think a shore fisherman could do well there using a variety of baits and trout/salmon lures.
I saw some very large fish in deep water and tried jigging sucker meet on dare devils ? but had no success. Maybe this method might have worked very early in the morning but I tried it at about 11:00 A.M.
One shore fisherman I talked was night crawler fishing on the bottom near the courtesy dock about half way between the marina and the dam. He said that his buddy (also night crawler fishing) had gotten a MAJOR hit and the fish peeled off nearly all of his line before the fish got itself loose. I did try jigging a night crawler several times but without success.
In summary, I threw about half of my equipment at the fish (including a skunk on a fly and a bubble) and caught about 30 fish (all small) in total over the span of a week fishing between about 06:00 to 12:00. I never did try parking the boat and salmon egg, power bait, night crawler, or marsh mellow fishing on the bottom. Maybe I should have.
