Pond Boss Forums POND CONSTRUCTION Building a dam 70 acre dam build

Looks like a very large project. If it were me in your shoes I would hire an engineer or at least consult with one on site first. Engineer should be able to give you some sort of fee proposal for the work and likely save you some huge dollars on a project of this scale. The money you would save may not be noticed until or if there was ever a failure in the dam but rest assured.....that never discovered savings would be much better than an oopsie at the start of the project that wouldn't be known until there was a problem later on.

Best of luck on the project.
