Low rainfall accounts for some of the drop in water levels on Lake Victoria. For this reason, the lake is very sensitive to rainfall, its water levels jumping depending on how much rain falls in a particular year. But Lake Victoria does not get water from a broad land region most of its water comes from rain that falls directly over the huge lake. For most lakes, the rain that falls over a broad region flows into the lake through rivers, streams, and ground water. “Lake Victoria is unique because the lake is a large majority of its rain basin,” Reynolds explains. The leaps and plunges in water levels happen because of Lake Victoria’s hydrology.
