Here are some pictures of where these were collected.
This first photo is where I collected the baby paddlefish, baby goldeyes, and 1 of the shortnose gars. My previous description may have over-exaggerated the size of this pool, but it always seems bigger when youre walking in foot deep mud trying to hold a net in the water without catching any of said mud. I imagine this pool will be dry within a week or two.

Here is the pool where I have caught most of the shortnose. It doesnt look very large, but it actually goes back into the trees where it gets deeper, and the actual water surface area is a few acres.
