dc.description.abstractAn attempt was made to measure the remaining storage of Tagwai Impounding Reservoir using bathymetric mapping and remotely sensed surface area data. A field study on Tagwai reservoir was carried out in Tagwai drainage basin, Niger State, Nigeria. The depths of water accompanied with their corresponding coordinates were measured from which area and storage were calculated based on data acquired from the field and that from satellite images. The remaining storage was at the time of measurement, in year 2010, the same as the total storage of the reservoir presently because the dead storage has been already silted up. Remaining storage was in year 2010, 21,650,648 m3 i.e. 76.5 % of the original storage. Thus, rate at which the storage shrunk from 1978 and 2010 is 207,792 m3/ year. Losses to siltation are 6,649,352 m3 during a period of 32 years. This corresponds to the average annual loss to siltation of 0.73 %. The reservoir will be completely silted up in 136 years from the date of its impoundment i.e. in the year 2114, if the rate of siltation is not reduced by upgrading the environment in the drainage basin.en_US
