The Site

Sinking Creek runs past Drey Land camp and forms one of the camp's boundaries. Water enters the creek continuously from numerous springs located throughout the region, or as runoff, following periods of rainfall. Maps of the Ozarks show that the creek collects water from a drainage basin of approximately 160 square miles. Fall along the main channel averages five feet per mile. Studies have been conducted along much of the creek's main channel but the data reported here are from a site just below the main lodge of the camp. At this location the surrounding bedrock is composed of limestone and dolomitewhile the river bed consists mainly of medium sized chert fragments. Because of this structure much underground flow beneath the channel is to be expected. The Sinking Creek drainage basin is relatively undisturbed by man. Limited lumbering, some cattle grazing and seasonal recreational use appear to be the primary human activities in the surrounding area.
