I'm not trying to be evasive by design. I thought that a before and after pic of a pond project might be of interest here. Particulars that might not have already been covered are :
The dam crosses a narrow location in the creek (about 70') and is ~800' in length, and extends into pasture areas on both sides. There are 30' of emergency ov areas on both common elevation end points with drain off berms. A 12' siphon pipe with valve extends thru the dam. Only once during a very heavy rain has the emergency areas been needed. Clay soils imediately in front of the dam were used in its construction. A Windows program was used to estimate volume and dam yardage. No dozer work was done upstream of the immediate dam area. The ov and pipe were lowered from the origial design due to concerns of an upstream county road. This reduced the surfaced area by about 30%. I don't have other pics to post at this time, but will take some later. I found this old pic on Photobucket that was taken during construction.
