For starters, I'm betting 8 feet is rather shallow for a Nebraska pond, given 1) lower rainfall and 2) cold Winters. 10 feet is about the minimum suggested for Ohio, with higher rainfall.

From a completely ignorant standpoint, I wonder if any normal pondbuilding operations (the dirt work, mostly) are more difficult to do in Winter becuase of frozen ground. Compacting a core, for instance.
