Eddie,
Not sure if the farmers use irrigation around you way but if they do you may be able to find a used portable irrigation pump with a diesel engine on it for a decent price then just put a 250 gal. fuel tank next to it and let it run till the lake is full. Then you will have it if you need some water to fill the lake in the summer and if you want some nice green grass in the park buy a used reel irrigation system and pump it out of one of your ponds. Not as cheap as you want but if you find one that requires some work it may be worth it.
