A contractor has recently installed automatic gauging stations around the Mara River Basin. The stations will automatically record water depth so that the water authorities can more accurately track changes in water discharge.
The contractor appears to have made a minor mistake at this station. I'm not sure, but I think the pipe that you can see in the picture (the one coming out from the bank) is that pipe that is supposed to transport water to the stilling well where the water depth measurement is actually taken. The contractor installed the station under high flows so the station will probably not be capable of taking readings of any of the low flows.
