Good advice given. Here in Michigan with all of the foliage that means a lot of heavily stained water. Fortunately the Brookies that usually inhabit them are typically aggressive, even still though I try and use a light line and longer than usual leader/tippet. Whisper soft casts whether using wet or dry flies are the order of the day, and after a catch I like to shift the spot I'm focusing upon to another to give it a chance to settle back down.
Consider working the water inlet area as it runs cooler, and contrary to that the edge of the damn. Though everywhere else you might find luck as well, those spots typically yield higher catches for me. Finally, don't go using your favorite fly of Granddads, expect to lose some as there is often a lot of little twigs, branches and so on just under the water all over. As mentioned above they're typically full of silt. So unless you intend on ending your day there, any snagged flies just break off and tie on another.
B.E.F.
