Lake Hayq is one of the highland lakes of Ethiopia that furnishes very important ecosystem services, fishing, tourism, transportation, drinking water, livestock watering, and irrigation. However, the lake ecosystem is being degraded by pollution, siltation, and excessive growth of macrophytes, buffer zone degradation, overfishing, and climate variability. Therefore, this study was conducted to assess the physicochemical, heavy metals, and biological water quality parameters of Lake Hayq. Physiochemical (pH, water temperature, conductivity, TDS, total alkalinity, dissolved oxygen, Ca2+ , Mg2+ , Na+ , K+ , NH4+ , NH3 , NO2 - , NO3 - , CO3 - , HCO3 - , SO4 2- , PO4 3- , SiO2 , and total phosphorus), heavy metals (Pb, Fe, Zn, Cr, Cu2+ , Mn2+ , and Ni), and biological (BOD5 and total coliforms) water quality parameters were analyzed both in situ and ex situ...
