Scouting dad. The idea for dam born when my wife and I took our two kids on a white water rafting adventure in the mountains of Tennessee and NC. Great memories I have of those times.
Capetrainman .the river has a foam base which is carved out and painted for depth. We are pouring a 2 part resin for the water effect. Will put ripple effects below dam for turbine effects when the pour is done on river.
Hopefully will have some more pics soon. Thanks for asking .
