Why are some locations reporting hundreds of feet for their river gauge and others not?

You may have noticed above some locations like Toad Suck Lock and Dam report a level in the hundreds of feet. The reason for that is because this gauge is based on the elevation of that location.

If you look at the Little Rock gauge, that site is based on the depth of the water from the floor of the river.
