I would also examine the satellite view of the areas adjacent to your property. If you see abundant small ponds, then the odds of favorable circumstances on your property are probably pretty good.

You might even check the elevation of the dams in your area. In regions where the bedrock has a low stratigraphic dip (slope), the elevation of the bedrock will be nearly uniform across the area. For example, if there are essentially no dams constructed where the ground level is 760' to 780', then that might mark a 20' thick bed of fractured siltstone that would be a nightmare for dam construction.
