Indonesia population is the fourth largest in the world and its growth will be followed by pressure on the environmental damage. Some of the problems of inland water in Indonesia are common, such as turbidity, water pollution, eutrophication and the loss of endemic species could be observed. Monitoring and management of land around the waters of a lake or reservoir are necessity to be studied. The objective of this study is to analyze the specific problems in the catchment area and sediment accumulation in the future those influenced the decreasing of fisheries productivity. In addition some local fishes were also decreased. Based on analysis on fisheries, the potential of fish production based on productivity waters of Lake Limboto ranged from 48.583 to 364.301 tons/year or lower than the level potentially based on catches of 746 tons. The high level of exploitation of fish production note to remember if this continues it will affect fish populations and the availability of existing resources. The area of the lake that continues to constrict also need to be considered to maintain the availability of habitat for fish that live in Lake Limboto. Next, spatial arrangement with respect to the impact of climate change needs to be analyzed based on the hydrodynamic characteristic of the area. The research activity is expected to produce an outcome study of lake management for fisheries productivity and can respond to the challenges of environmental problems in the future.
