The Murchison Bay Watershed in Uganda covers an area of 40.9 km2. The bay is a part of Lake Victoria and its watershed is located between latitudes 00° 10′ 00″ N and 00° 30′ 00″ N and longitudes 32° 35′ 00″ E and 32° 50′ 00″E. The average elevation is 1,224 m above sea level. The average annual rainfall in the watershed is 1,290 mm. The Murchison Bay Watershed supports a variety of human activities. Core changes in the watershed include: urban expansion (29%); and, decreases in agricultural areas (18%), forests (6%), and wetlands (7%). Anthropogenic perturbations particularly land use/land cover change are primary threats in the watershed and watershed water quality and quantity in the bay are impacted by a combination of urban and agricultural pollutants.
