I have a pond and I'm trying to figure out how to determine how much water is coming out of the overflow culvert. It runs like this year round, and I'm thinking about a low head unit from Langston Alternative, but I'm not sure how to figure out if the pond will support a 6" siphon.View attachment 34192View attachment 34191

I don't think i have enough head for that type of setup. It's only about 10' from the surface of the top pond to the surface of the lower pond.I suggest routing the 6" pipe to four nozzles on the turbine, 2 always on and the other two controlled by an electric valve and float switch in the pond. It should get 100% for a wider range of flow that way.
You don't think a v notch weir would be accurate on the end of the culvert?You would want to measure the water on the pond side or intake side of the pipe if you use the weir method...
