When irrigation season rolls around the water table can get drawn-down considerably...on some of the isolated bodies of water with no flow coming in or no direct ground water influence, evaporation and evapotranspiration can reduce water levels also.
That's why a spring or creek is nearly essential to have on these fairly small isolated watershed dams being constructed...if there is zero water source even run-off, it doesn't matter how deep the pond is it won't be suitable for fish habitat.

I'm not familiar with irrigation systems. We've never done it and don't expect to. Why does this draw down the water table?
This picture is an old one, but it shows the creek that flows through the property and the pond site. The red circle furthest south is the one we decided on after considering the other 2.
However, as you can see in this diagram, the creek is at a much lower elevation than the pond. Nice for preventing a creek flood into the pond. Bad for even considering using the creek to get water into the pond.
