Hello,
As an Oklahoma resident who has recently built a pond I can tell you that the hot dry summer wind will rob ponds of significant amounts of water. To help minimize the impact of the hot dry summers make sure your pond is properly laid out and constructed. Contact your local soil conservation agent for assistance and find a contractor that will build the pond using correct design and construction methods. My personal advice is if they don't use a "sheep's foot" roller to compact your pond don't use them. Anyone can dig a hole for you and it might work fine, but if it doesn't then be prepared to spend big $$$ to get it fixed. I know this from experience. I have a leaky pond due to improper construction and it is going to cost as much or more to fix it as it did to build! Do your homework and don't just blindly trust your contractor to do the job correctly. Once your pond is up and running be sure to contact the OK. Dept. Of Wildlife for free fish.
Best wishes,
Patrick
