Pond Boss Forums STOCKING A NEW POND Types of fish to choose Declining Water Level

Welcome to the forum!

Cleaning out the Springs will do nothing. Springs do NOT have a one way valve on them, so if the water pressure is higher in the lake than in the spring, it will flow backwards. What you have is called a groundwater lake, I have a groundwater pond. For the last 3 1/2 years mine was as low as 9 feet vertically below full pool.

You can pump water into it to fill it, but first you have to know how much water you are loosing.

Go get a metal yardstick and a piece of stiff plastic or EMT tubing. Pound that down into the pond bottom and zip tie the yardstick to it so you can read it easily and the yardstick doesn't slide up or down on the tubing. Put it in 12"-24" of water and once it's in there make a note where the water level is. Look at it daily and record the measurement. After a week you will get a good idea how fast it's dropping (vertically).

1" drop in a 15 acre lake equates to 407,313 gallons of water.
