These are the design values. In practice, the runoff from the catchment is largely insufficient to fill the reservoir, which serves only as shallow drinking pond for livestock.
Environment.

Land use is strongly dependent on lithology: soils on metamorphic black limestone are used for cropping, while those on the schist and slate formations are under savannah woodland. Lands on the green-reddish-gray metamorphic banded marl formation are used for settlements. Most common soil types are:
