Pond Boss Forums POND CONSTRUCTION Building a dam How do you build a dam with a flowing creek?

I don't think it is esshup. The water originates in my swamp (full of springs), but it does dump into a local lake that would be approximately 500' down stream. I have spoken to someone with the Michigan DNR in the past but did not have them out to look at the property because at the time I wasn't ready financially to start the project. I'm just curious how the logistics of building a dam and dealing with the water works. The creek is only a few feet wide, but it has a good flow of water.
