So you don't have to pay to park. Park at the dog park. There is a tunnle under the road right to the lake. All along the road there the fishing is pretty good. Park at the vister's, and have a short walk to the inlet (another great place to fish). You can even wade up the river through the golf course. Park at the golf course. We call that Fisherman's Nook. You park right on the lake, and it's probably the best fishing spot.
The report sais fishing is fair to good using Power-bait or worms. Salmon eggs always work as well. Try small gold lures. For flies, call Kirk's in Estes and they'll let you know what they're hitting.
I aslo reccomend Mary's Lake. Last year my dad and I had no luck in the park so we saw Mary's and fished it even though we hadn't ever heard of it. Off a rocky point we caught 4 nice trout. A small Rapala Countdown worked for us. We didn't have to cast it far. That was a year or two ago, but it may still be that way.
