Having a pond on your property to swim in, fish, and relax by is a great enjoyment. Building a pond can be as simple as digging a hole in the ground or more complex when excavation equipment is involved. Think about how you are going to use this pond to help determine size and depth. To reduce the chance of creating a swamp or a pond that holds no water, we would like to share a check list with you.
- avoid areas prone to seasonal flooding
- avoid regulated wetland soils
- directing streams or drainage tiles into the pond may cause future problems with nutrient management
- Drive around your area and find out who build the better ponds that you find.
- If you can run equipment do it your self. A dozer and trackhoe /excavator is needed.
- Have a written agreement for the work. Few contractors will return to fix a leak.
- Have a plan for soil management. Avoid moving it twice or having soil slide back in the hole.
- Pile the topsoil and cover it with seed or straw. Check with your zoning office to see if you can screen and sell the excess topsoil to recover your excavation cost.
- Dig a core trench under all dike walls to reduce water seepage.
- Remove all trees and roots within 40ft of dike walls to prevent seepage.
- Shallow water zones will probably support future cattail growth which can keep you busy removing them.
- Never use topsoil, shale, or large stone in the dike walls. Fixing a leak is expensive.
- Place anti-seep collars on all outflow or overflow pipes.
- If you must use a stream to fill the pond, build a fore bay to capture soil sediments and to act as a phytofilter.
