Pond Boss Forums POND CONSTRUCTION Building a dam Trench core / high water table

Thanks for the replies! This is what I'm working with- the stream runs year round, and has never been affected by a drought as the stream is 4ft wide, and roughly 6in deep. We have a large earthen spillway that was utilized as the primary pond level, but now we're looking at using a tandem 10in siphon system. FishinRod, I'll continue to read your description, but can you see what I'm dealing with?

The dam will run at a 45 degree from the left bank, and run alongside where the bank on the right is cut at an angle. That creek is roughly 5ft wide for perspective. (That dirt/stick crossing is temporary, and not the dam site.)

I trust my grader, but I get one shot to understand the logistics!
