Limestone is a good ramp, just doesnt have a dock or anything. It has a pretty good spot blown out from the prop wash so loading and unloading isnt a problem even when the water is low.. if you are looking for stumpy, limestone is the right place. From the ramp looking to the north all the way around to the South west is a huge flat that is full of stumps. There are a few dips and ditches. From the ramp looking east, if you draw a line, to the south of that line I would say the water averages 2.5-4 FOW range. There is a channel that runs from the ramp out to the river then there is another channel that Y's off the creek channel if you were coming from the river back to the ramp runs NE ish. There are several stumps that are marked with PVC pipe so you know they are there but there are 1000's of them that are not marked. Just go out there one Saturday when there hasnt been 4-5 inches of rain and you will see where everyone is fishing. 99% of the boats out there are crappie fishing. I idle from the ramp out to the middle where I start fishing, just leave the motor trimmed up. I definitely would not just jump it up on plane and take off across there until you got familiar with the area.
From Triana boat ramp it would be a pretty good ride to Limestone of Flint creek.
If you left limestone creek out into the main river its a short run to Flint, which is the next creek on the south side of the river if you are running back towards Decatur.
