The study was conducted in lacustrine wetlands located in the Khalong-la-Lithunya catchment (KLC) in the Mountains AEZ of Lesotho, in Butha-Buthe district. Investigations were made between 2009 and 2012 on the soil characteristics, hydrochemistry of the surface waters and vegetation isotopic signatures in order to assess the extent to which conservation and rehabilitation practices have allowed the wetlands to return to its former status. Results of the hydrochemistry from the installed piezometers showed that across years and months the variables (pH, EC, Ca, Mg, Na, K & NO3-N) were within the normal range, while the phosphate concentrations were beyond the limits. It was concluded that more research is needed to identify sources and forms of phosphates in this wetland
