thanks esshup will post a picture of a picture so it might not be to good of a pond i built 4 yrs ago that looked similiar to what he's describing above. the silt was over 10' deep in most of the pond area so we built the back half of the dam first then when we got to the clay-shale we finished the core and front of the pond. it was a miserable pond to build mainly because the silty soil wouldnt support a scraper and had to do without it the first half of the job but it turned out nice and was well worth the effort.
