3 HYDROLOGICAL ACTIVITIES The Hydrologic and Meteorological phenomena operating within any given sub-catchment dictate the water balance within the area and particularly the success of all water-based projects therein. Since inception of the Authority in December 1976, emphasis has been geared towards the collection, analysis and publication of the Hydro-meteorological data within its operational area. The planning, design and management phases of water resources infrastructure depend to a large extent, on the availability of hydro-meteorological data. However, because the hydro-meteorological processes are stochastic, each of these phases is characterized by uncertainties. The net effects of these uncertainties are economic penalties resulting from imperfect planning, over or under-design and wrong management decision. A way to reduce such penalties is through more comprehensive data records. It is generally acknowledged that in Nigeria, basic planning data are scarce, and the collation efforts are still at their infant stages. In an effort to bridge the existing data gap, the Authority has established a network of hydro-meteorological stations within its operational area. Although the present density of stations does not meet the required international standards; valuable information has been obtained dating back to 1978. A summary of the spatial distribution of the various stations maintained by the Authority is presented below: In addition, the Authority is cooperating with other organizations in the maintenance of Hydro-meteorological Stations established by them.

Yola Irrigation Project (Lake Gerio), Kiri dam Project, Shelleng L.G.A.

• The project was established as a pilot scheme in 1978 The dam primary function is to Irrigate 12,000ha presently irrigating 347ha by pumping from the Benue of sugar plantation for Savannah Sugar Company Ltd (SSCL), Numan, commissioned in 1982. River and Lake Geriyo. • The Farm has a potential irrigable land of1200ha. The Authority generates revenue from the sale of raw water to SSC Ltd. The project is providing gainful employment to about 1500 • farming families and employment to about 6,000 casual The reservoir has a storage capacity of 615 Mm3 workers. • The Dam has potential for mechanized fish When fully developed up to 5000 farmers will benefit from farming, and also mitigate flood during rainy dry season cultivation employing about 18,000 casual season through reservoir regulation downstream into Benue river. workers. • A prefeasibility study conducted in 2006 by UBRBDA, and UNIDO-RC-SHP Abuja, confirmed the possibility for hydroelectric potential of Rice farm at Geriyo Irrigation project Yola North LGA, Adamawa State 16MW installed capacity, • In December, 2009 Adamawa State Government signed an MoU with USTDA for feasibility study to upgrade previous studies to generate up to 35MW. • The study was awarded to M/S Princeton Energy Resources International of USA ,with active participation of the Authority. • The study confirmed the possibility of 20-30MW installed capacity with the help of Dadinkowa turbine releases during dry season.

3 Proposed Dasin Hausa Multipurpose Dam, Adamawa State

In 1981 UBRBDA commissioned M/S Hydroservice Sao-Paulo Brazil to conduct prefeasibility study for construction of a multipurpose dam about 30Km upstream of Yola on the Benue River. The reservoir design storage capacity is 16*109m3, will mitigate the negative effect of perennial flooding along the Benue river flood plains, about 150,000ha downstream, can be used for cultivation twice a year. About 1,200,000.00tons of grains equivalent/per annum can be produced from irrigation, the study identified the irrigable area as highly suitable for sugar production. The dam can generate 150MW of hydroelectricity at designed installed capacity of 780GWh/year. Provide navigation throughout the year upstream of the dam to the inland port of Garoua in Cameroun Republic, and increase inland navigation period of about two months downstream to Lokoja.

Inspection of power house by officials from UNIDO- RC-SHP 7 Dadinkowa Multipurpose Dam, Yamaltu/Deba L.G.A, Gombe State. The Construction of the dam started in 1981 and completed in 1987. The Dam has a reservoir capacity of 2.8*109m3, live storage 1.77*109m3, made of earth rock-fill embankment, crest length about 520m, maximum height 47m, Ogee Crested Spillway equipped with radial gates and Power house. The H.E.P has a design installed capacity of 34MW, electricity generation output 224.74GWh/annum that can generate revenue about N2.25 billion gross, at N10.00/kwh The Dam has a potential to irrigate about 25,000ha net downstream which can produce about 200,000tons of grains equivalent twice a year that can generate about N6billion gross. Through mechanized fish farming, about 20,000tons of fish can be harvested annually from the reservoir that can generate about N10b at N500.00 per kg. Presently only 100ha is under irrigation, by abstraction of water from the river, due to non completion of the irrigation scheme. Under the FY 2009 the contract for the continuation of work on main canal (1.3km) is in appreciable progress.
