As Tennswede said, you can catch them right of the blacktop. Don't overlook the "skinny" water as you might be tempted to do and they can be easily spooked. Some of the larger fish I have seen were scurrying for cover because I had allowed them to see or hear me.
I'll echo the words of WRN, pinch down the barbs and release them carefully. Nothing in the fish world is as beautiful as a Brook Trout!
Good Luck, gary <*))))><
