Pond Boss Forums POND CONSTRUCTION Building a dam How to finish the pond right?

Hi All,

I was fortunate enough to find Pond Boss now that I'm finally wrapping up pond construction

Soil was 2 feet of beautiful topsoil (little heavy on the clay/organic side), under that hard stcky tan clay with some gravel & rocks mixed in.

Pond is about 50'x90' 7 feet deep at the base of the dam sloping to about a foot or the opposite edge.

I installed a 4" PVC drain at the base about 2 feet up with a 90 elbow pointing down to keep the water down during completion/landscaping & in case it needs draining.

Installed 12" primary drain at the top, and intend to put 12" spillway off tp the side.

Water supply is 90% rainwater, which is constantly trickling from elevation, but is all the 4" can keep up with during heavier rains.

I have a couple questions for those with experience though: how will a dirt/clay mixed dam faced with 6-12" of clay hold up? I do have seepage around 4" drain (not compacted or faced yet).

Should I get regular fill put in at the backside of the dam to add bulk/weight/stability, or is my mix good enough?

Also what should I get for the road immediately upstream? The clay mix dirt is clearly not the best choice for this...

Any thought/suggestions/corrections/comments on how to do this right before landscaping around?

How do I get the pictures on here for you to see them?

Sorry so lengthy, but lots of questions!

Thanks a lot Russ,

Lets give it a try...











OK, lets see if that worked...

If so any "requests" for areas to be posted for evaluation? Seems solid to a "backyard engineer", but the folks at General Mills could revoke my credentials at any time!
