Turn off the power to your well.
Take the cap off the top of the well.
Use a string with a weight securely ties on one end.
Lower the string down the well casing until it stops.
Tie a knot in the string at the top of the well casing.
Pull the string out. Measure form the end of the string to the know. This is the depth of you well.
Put the cap back on.
The next morning when you try and fill the chickens waterers and you discover you don't have any water...turn the power back on to the well.
