The largest lake (Basikoma) normally has muddy water prior to the rainy season. The lake if dredged may store enough water for irrigation (Vegetable, etc.) during the dry season.
The Dry Season
In the dry season, agricultural operation is impossible without irrigation. Farmers move to cities, creating population density and poverty. The dry season is one of two seasons in semi-arid Africa. The dry season is characterized by low humidity, lack of water and depletion of subsistence crops between November to April yearly.
The Rainy-Wet Season
The rainy or wet season occurs during a warm season, or summer, precipitation takes place. In the wet season, air quality improves, fresh water quality improves, and vegetation grows substantially, leading to crop yields late in the season. Rivers overflow their banks and drains into lakes along the white Volta river networks.
Dredging Existing Lakes
UTAP proposes expanding five (5) midsize lakes spreading along the White Volta, dredged or dug-up to regain lost storage, improve water supply reservoirs, improve fish habitat, and use nutrient-rich sediments for planting of fruits and vegetables. None of the lakes sediments are considered contaminated in any form.
