I've been to Douglas Lake when the water hasn't fully gone from Winter Pool to Summer Pool .... and was told that most people fished the shoreline for Crappie in the Spring, and when I was there that "shoreline" was probably 15ft above my head as I sat in the boat.
I checked and the Summer Pool elev. is 990 -- Winter Pool elev. is 955* (*estimated)
When I looked on Google Maps at the lake .... people's boat docks were high & dry (by a LONG way )
