I'm having a dam constructed across a creek that
runs thru my property. The creek drops about 12 ft over 1500 ft from a county road. I'm
planning on bringing the water level up to the
culvert pipes below the county road. The creek is quit deep and about 200 ft wide at some points.
The dam will be constructed at a narrow (about 50' wide) location about 1600 ft down from the road. The soil is mostly clay, but the creek sides have a heavy concentration of silted black soil. Can such a dam project as this be core trenched ? Most of the soil for the dam
embankment will have to be pushed from the
silted creek sides. I plan on two 10" pvc siphon
pipes for overflow. Does anyone have info on
creek dams such as I've described ? I talked
to the NRCS people, but they were unresponsive.
