Best Water Depth for Pond

Water depth is an important characteristic to consider when building a pond. Generally, the deeper the pond and the steeper

 the grade, the better.


The deeper the water in the pond, the less sunlight will reach the bottom of the pond. If pond weeds can’t get enough sunlight, they will grow much slower and sometimes not at all. Once a pond is around 8 to 10 feet deep, the weeds will be less likely to flourish and, if pond dye is added, they usually slow down even more.

The deep water of a pond also allows water to remain cooler throughout the summer months. Having most of a ponds depth between 10-12 feet is ideal. The ideal average water depth is 8 feet.

Some people love beach areas. Just make sure you are prepared to treat these areas for weeds and algae. Shallow areas are highly likely to have persistent growth. Remember, the deeper the pond, the less weed and algae problems you will have.

Next week we will post about why pond slope is an important consideration to discuss when digging a pond.
