Put a foot valve on the suction, or it will ALL run back into the lake.
T a ball valve into the line next to the foot valve if you need to drain
the line for the winter.
There are self-priming pumps that will suck air until the water gets
there. I don't know how long they run, they are designed to self-prime
at a very low head, and need water in the pump to do their thing.
When I was a kid, we used to prime an irrigation pump with a hand
suction pump. We would just pump like crazy for a few minutes, then
kick the pump on when the water got there. It had a 6" suction on it,
so we were moving a lot of air. It was a diaphragm pump.
