Description
Summary:Maninjau Lake can be found in West Sumatra province, specifically in the Tanjung Raya District of the Agam Regency. The Government and the nearsocieties utilize the lake catchment area aimed at agriculture, refreshment, settlement and floating net cages. Increased anthropogenic activity can affect the quality of the lake. This investigation’s goal is to assess Lake Maninjau’s water quality using the Pollution Index (PI) and the Storage and Retrieval (STORET) method. The research was showed at five sampling stations in the Maninjau Lake area from November 2021. The water quality in Maninjau Lake is classified as moderately polluted by the STORET method. Nonetheless, the Maninjau Lake’s water quality falls under different categories according to the PI. From Good condition to Moderately polluted is the range for Class I (in use as a water source for drinking). Lightly to Moderately polluted is Class II (outdoor recreation assets and facilities, fishery, livestock farming, and agricultural uses). Class III, on the other hand (meant for breeding freshwater fish, raising livestock, and watering crops) and Class IV irrigation systems are categorized as Good condition and lightly polluted, respectively.
