Rend Lake Facts & Figures
The Corps of Engineers
Builds Rend Lake
Construction of the sixty million dollar Rend
Lake project began in June 1965. The
initial filling of the reservoir was complete in May 1972. Located on the Big Muddy River. Rend
Dam is 103.7 river miles from the
Mississippi River. The dam creates a
lake with a surface area of 18,900 acres at the top of the joint-use pool,
which is elevation 405 ft. NGVD (National
Geodetic Vertical Datum). Subimpoundment dams were constructed on both
of the major tributaries to the lake, approximately 10 miles upstream of Rend
Dam. These structures help create an
approximately 5,000 acre wildlife management area on the northern end of the
lake.
