Photograph of a close-up shot of native grass in area sprayed for oak brush control. The back of the photograph proclaims, "Native grass in area sprayed for oak brush control, in 1957 and again in 1958. Large plants of little bluestem, Indiangrass, switchgrass, and big bluestem made seed in fall of 1957. Small grass plants are seedlings of above grasses. Deferred grazing has made it possible for rapid range improvement following spray jobs."

Photograph of Arnold Snowden holding a carp that attempted to enter the lake from the creek, though the emergency spillway but was trapped by receding discharge. The flood storage with drawdown pipe reduces the number and duration of emergency spillway flows, thus reducing the hazards of wild fish infestation.
