It looks like you're emergency spillway is going over the top of the dam, if so you should move it to the undisturbed area, where the dam meets the hillside.

I'm in SW VA in the Blacksburg area. The water source is a spring. It runs about 10-15gpm (I'm guessing here based on a garden hose being about 6gpm) year round without rain. I can tell you the 3 inch over flow pipe works about at capacity when it isn't raining. When it rains hard I get at least double the flow. I am worried about freezing as well. I received advice not to worry about it but am hesitant. Blacksburg definitely gets freezing conditions throughout the winter. I would assume the experts will tell you 3” pipe is undersized for the watershed. Most ponds that I have seen in VA have the overflow pipe buried in the dam with a T and the vertical pipe length setting the level of the pond with a trash rack on top to avoid clogging. This is what I decided to use on my pond as well as having a drain on the horizontal inside of the pond. I’m not saying that this is the only way by any means. DC70’s design is fantastic but I couldn’t find anyone around here who knew how to build it. One tip that I can recommend is to lightly sand and paint the exposed portion of white pipe so it doesn’t degrade from ultraviolet light exposure. On a separate note what kind of dog training do you plan on doing with all those ponds? Heppy

I compete in Retriever Field Trials. I have Golden and Labrador Retrievers. My biggest reason for not wanting the overflow pipe at water level in the pond is my dogs might impale themselves when leaping in. They enter the water with reckless abandonment.

A trash rack should eliminate that concern. Just a thought. Heppy

My 2 kids are IT professionals and suggested Imgur (free online photo storage). This has worked perfectly for me. The flying dog literally broke her neck and is in a brace for 8-12 weeks. Her muscularity is what saved her.  I believe it. Glad she is going to make it.

I have seen dogs hit them. Crazy, but true.

My drain pipe is under a fixed dock. Best to also build a wire panel box around the drain pipe.
