Chilled by the massive surface of Lake McConaughy, a breeze sweeps gently eastward across Kingsley Dam and tumbles 160 feet to the surface of Lake Ogallala. There, at the "little lake," anglers and campers enjoy the natural air conditioning, but sunset comes early in the shadow of the towering dam to the west. Born simultaneously in 1941 with the construction of Kingsley Dam, Lake McConaughy and Lake Ogallala are litter mates, but not twins. Lake McConaughy is big and rough 35,000 surface acres big and even gentle breezes often lead to heavy swells. Lake Ogallala, at 320 acres, is comparatively small, gentle and sedate. Its protected shoreline wards off winds that would send the big lake into torment. Lake Ogallala is a rag-sweater-and-cup-of-coffee lake, not a sweat and Gatorade lake like its sibling.
