yea its a tricky thing to figure out. Wheeler level is measured at wheeler dam. Anything under 50,000 I consider good. Also if fishing east of the RR bridge in Decatur it is tricky when they are pulling a ton of water. All of that water has to go under the RR bridge with is pretty narrow considering the rivers width in some spots then the inflow from limestone and flint creeks. If it has came a big rain and they are pulling 100K plus you can expect Decatur area, flint, and limestone to be around 2 ft higher than what the app is saying wheeler is.
