Its a oxbow cutoff from Bayou Macon. There are 3 that run from below i-20 south of Delhi, down to Gilbert
The first is called Bakers cut-off, the second is just out of Crowville, and I forget what its called, and the 3rd is Lyles cut-off just east of Gilbert. they are fishing lakes, no ski boats ( to many stumps) . they have Bass tournaments from time to time.
My wife and I have a small camp on the lake and we enjoy drinking our coffee and fishing a little while in the mornings and evenings. The lake is from 100 yards to 150 yards wide and I dont now how many miles from one end to the other, but its a ways.
