Does the level of your pond fluctuate much Duckdude?

Down in El Dorado county we have huge fluctuations in pond levels due to the long hot and dry summers. I'm guessing that you'd be in the same situation unless you bump with well water or something. DIED's pond and mine will drop 7 to 8 vertical feet from end of the spring rains to the beginning of fall rains.
