Thanks for the helpful insight Quarter Acre and Bobbss. Bobbss, I may take you up on your offer! I just heard about permitting due to the Taum Sauk reservoir dam break. Not sure the cutoff in dam height but it may be in the upper 20 ft range. Also not sure how to calculate watershed, but by the look of the contour lines it may be about 6 acres. Sounds like I may need to do a smaller pond. Thanks again for the forum.
