Does Rattlesnake Lake offer any good shore fishing?

No. But it does offer decent rainbow fishing when the water level is low enough for good bank access.

Selective gear rules: Single barbless hooks, no bait (inlcuding power bait....).

I have fished Rattlesnake for about five yrs now and there is plenty of shore access, but its all no bait and single barbless hooks like Phish said. The trout are OK mostly small ones with the occasional triploid or holdover. Lotsa fly fishermen in float tubes. Use to be a nice quiet place before they put in the park. Now on the weekends its a zoo, boomboxes blasting, kids running allover leaving trash on the ground, motorhomes, you get the picture.

Yeah, and the worst part about the park is the County doesn't even maintain it - what a mess.
