Reservoirs have been found to
provide a convenient source of water for different purposes to rural
communities and this makes them indispensable, and they are quite important in
improvement of livelihoods of rural community. The study applied Geospatial
techniques in assessing the Dadin Kowa Dam Water level in Gombe State, Nigeria.
To achieve the objectives of this study, two major data were acquired. The
water reservoir level recorded from 1987 till 2013 was collected from Upper
Benue River Basin Development Authority also Landsat satellite imagery from
1987, 2000 and 2015 were acquired. Supervised image based classification was
applied to assess the class of land use land cover in the area of study. The
extents (surface areas) of the Dadin Kowa Dam were delineated from Landsat
satellite images using the Normalized Difference Water Index (NDWI). the water
level record was arranged in Microsoft Excel and the mean of the water level
for 1987, 2000, and 2015 were used to assess the change both in extent and
volume. The result shows that from 1987 to 2000 the water level increased and
decreased from 2000 to 2015 due to the climate change condition and the high
rate consummation of water due to population growth of the area from 266844 in
1991 to 367500 in 2016. Dadin Kowa reservoir may completely dry up by the year
2029 if the climatic condition remains as it is.
