Reservoirs and stagnant streams created by dams can be conducive for mosquito breeding.
People living less than one kilometer of the Koka Dam in central Ethiopia are nearly three times more likely to get malaria than people living one to two km away, and nearly 20 times more likely to contract the disease than people living more than five km away, according to research by the Sri Lanka-based International Water Management Institute.
The study also found that better management of the water releases from the reservoir can reduce mosquito breeding grounds and decrease malaria transmission.
