Thank you for your replies. I have been cutting the flies off when swallowed deep but wanted to be sure it was appropriate. In answer to the questions above; the lake has bass in it also. There are a lot of bass fishermen who fish the lake. Most of them use very large crank, buzz, jug, worm and other types of artifical lures. The lake only allows artificials. ( Lures, not fishermen ). In answer to JW's popper remark, the lake also has a great deal of algae and water plants around the edge so surface flies are the ticket. I use foam spiders mostly and have caught lots of bluegill and some bass on them. I haven't had as much luck with poppers though I am starting to tie deer hair and hope that they will entice some bass. Thanks again for the replies.
