I just found this forum, what a site ! I need help too. I'm in the process of having a dam built and would like some advice on how much structure should I leave for the fish ? If you have time, feel free to check out the web page I've created for this project : www.geocities.com/russeldean2002 It will be about 23 feet deep in the center pit, the water will back up and fill approx 8-10 acres. Right now I'm cutting down literally tons of trees, there's no way I can haul it all out. I still have about a month before the dozer comes back in, what's the right way to proceed ? How much should I save for habitat, any specific way I should do it ? Also, I can easily separate and burn specific types of trees if they pose a problem...any advice as to how much and where, are there key areas to target, i.e. creek bed dropoffs ? Thx in advance, I can't wait to ask all my other questions as I go forward !
