Damn! That must be hard labor...constructing a damn. LOL

Use pather martain spinner 1/32 gold with orange tail it's called the deluxe sell them at dicks sporting goods and wallmart. also try yellow or green power bait and worms small red ones work good also, if you can get meal worms or wax worms try them also. minnow is excellent flat heads

Kastmasters, red and blue or chrome.. You will have a blast with trout without a doubt.. I find them more deadly than spinners when it comes to trout and cast further also..They wobble back and fourth when retrieved.

Sometimes I use them as well only in the copper or brass color as bright light can bother some trouts eyes and they do not react to them so good. Also I will add a piece of worm to the back of it for a trailor..

Exactly, So if you are gonna keep the ones you catch, then have it. If these are wild trout and you are just catching them for fun and releasing (as many trout fisherman do) it's actually probably best to leave them alone until the water cools down. Catching them in 70 degree water will probably kill them. Sounds like the dam repair is having a direct impact on those fish and as soon as things normalize again, the fishingwillbe in a more healthy environment for them. Sounds like they are congregating in the "holes" because of the low water.
