Welcome to the PB site and to Missouri, I have learned very much on pond build from this site. I have been working on a pond for more years than I care to mention, but I am building it myself with the help and knowledge of the site, I did get it cleared, keyway and dam, but being a PM for a construction company I have traveled most of the year for the last 10 years. Only been able to work on it a few days a year. In February of 2018 in a weekend of rain It was full, note I was not finished building yet, sooo I have a problem trying to finish it as it is still full ( it did go down about 3/4 of the way last summer but has since filled up again. enough said, good luck. It really is labor of love.
