Management Challenges for Deer Creek in the Mississippi Delta

Author(s): Killebrew, R.

Rivers and central are paramount to surface water ecosystems. Many characteristics differentiate lake ecosystems from running water. Areas with flowing freshwater are called lotic (lotus, from lavo, to wash) and water moves along a slope in response to gravity. Lotic ecosystems are contrasted to lentic (lenis, to make calm) or lake ecosystems. Most lakes are open and have distinct flows into, through, and out of their basins. Throughflows, called water renewal rates, are often variable and slow in lakes but are continuous.

The distinction between running waters and lakes focuses on the relative residence times of the water. The importance of variable but continuous and rapid throughput of water and materials contained within is evident in the biology of most organisms living in running waters. When the energy of flowing water is dissipated, like it does in the transitional zone of reservoirs, the change to lentic characteristics is rapid.

How does one manage a water body that, for most of the year, is neither stream nor lake? Deer Creek in the Mississippi Delta is more like the Dead Sea in many respects. For much of the year it has no outflow and very little inflow. Deer Creek has a very small basin area because it is a perched water body.

This presentation will provide a glimpse into the many challenges of balancing the needs of the water body inhabitants with the needs or desires of the people who live along the water body.
