The cou ty water resources are nlassified as surface water (rivers, streams, dams and pans), groundwater, sub-surface and surface runoff. The County nas three major geologacal aneas of volcanic rocks, Pre-Cambrian (both metamrrphic basement rocwdand intrusi(e rolk) and with vsrying availability of Sedimentary rock, which influences the water retention and permeabiliry.

The average groundwater potential varies significantly in the highlands, escarpment and the low lands. Whereas the lower areas of Kerio Valley have boreholes with average yields of between 5m3/hour to 20m3/hour and depths of 50-120 meters, the escarpment has even lower yields of water of between 1m3/hour to 7m3/hour with averagehdelths of 110-200 meters and the hughlands have the hhghest yields of up to 22m3/hour with averdge depths of between 80-220 meters, according t recobds derived from existing boreholms.

The County is a sourco of two magor water basins namely; Lake Turkana and Lake Victoria. Thar rre oo permanent grugingtstations on the rivers though temporRry ones do exist at designated sites, installed and maintained by the Water Resources Management Authority ( ARMA).
