Osun ( pronounced ; /ˈōSHo͞on/ ) is an inland state in south-western Nigeria . Its capital is Osogbo . It is bounded in the north by Kwara State , in the east partly by Ekiti State and partly by Ondo State , in the south by Ogun State and in the west by Oyo State . The state 's current governor is Adegboyega Oyetola , who was declared winner of the September 2018 governorship elections . He was declared winner of the 27 September 2018 rerun elections after the initial 22 September 2018 gubernatorial election was declared inconclusive by the Independent National Electoral Commission . Osun is home to several of Nigeria 's most famous landmarks , including the campus of Obafemi Awolowo University , Nigeria 's pre-eminent institution of higher learning . The university is also located in the ancient town of Ile-Ifẹ , an important early center of political and religious development for Yoruba culture . Other important cities and towns include the ancient kingdom-capitals of Oke-Ila Orangun , Ikirun , Ila Orangun , Ijebu-Jesa , Ede , Iwo , Ejigbo , Ibokun , Ode-Omu , Ifetedo , Esa-Oke , Ilesa and Igbajo .
The Erinle River is a river in Osun State , Nigeria , a right tributary of the Osun River , which it enters from the north near Ede just below the Ede Dam . Another reservoir , the new Erinle Dam , lies higher up the river . Water from the two dams supplies Osogbo , the state capital . There are significant health issues with the untreated and treated water .
Oyo , usually referred to as Oyo State to distinguish it from the city of Oyo , is an inland state in south-western Nigeria , with its capital at Ibadan . It is bounded in the north by Kwara State , in the east by Osun State , in the south by Ogun State and in the west partly by Ogun State and partly by the Republic of Benin .
The Asejire Reservoir is in Oyo State in the south west of Nigeria on the Osun River , about 30 kilometers east of Ibadan . The reservoir was built in the late 1960s . Farming is totally banned in the catchment area , and trees have been planted on the banks , so erosion and silting are not issues . With plentiful water supply , the reservoir remains full throughout the year . The reservoir provides raw water to the Asejire and Osegere water treatment plants in Ibadan . The water supply project was completed in 1972 , and has a capacity of about 80 million liters per day , of which 80% is used for domestic purposes .
Sokoto , usually referred to as Sokoto State to distinguish it from the city of Sokoto , is located in the extreme northwest of Nigeria , near to the confluence of the Sokoto River and the Rima River . As of 2005 it has an estimated population of more than 4.2 million . Sokoto City is the modern-day capital of Sokoto State ( and its predecessor , the Northwestern State ) . The name Sokoto ( which is the modern/anglicised version of the local name , Sakkwato ) is of Arabic origin , representing suk , market . It is also known as Sakkwato , Birnin Shaihu da Bello or Sokoto , Capital of Shaihu and Bello ) . Being the seat of the former Sokoto Caliphate , the city is predominantly Muslim and an important seat of Islamic learning in Nigeria . The Sultan who heads the caliphate is effectively the spiritual leader of Nigerian Muslims .
The Bakolori Dam is in Sokoto State in the Northwest of Nigeria , completed in 1978 and its reservoir filled by 1981 . It is a major reservoir on the Sokoto River , a tributary of the Rima River , which in turn feeds the Niger River . Water from the dam supplies the Bakolori Irrigation Project . The dam has a capacity of 450 million cubic meters , with a reservoir covering 8,000 hectares extending 19 km ( 12 mi ) upstream . The dam construction project displaced many peasant farmers without providing alternative land or financial compensation . Many people died in protests over their loss of livelihood . The project has become known as a classic example of development failure .
Kano State is a state in Northern Nigeria . Created on May 27 , 1967 from part of the Northern Region , Kano state borders Katsina State to the north-west , Jigawa State to the north-east , Bauchi State to the south-east and Kaduna State to the south-west . The capital of Kano State is Kano . The state originally included Jigawa State which was made a separate state in 1991 .
The Challawa Gorge Dam is in Karaye Local Government Area of Kano State in the Northwest of Nigeria , about 90 km southwest of Kano city . It is a major reservoir on the Challawa River , a tributary of the Kano River , which is the main tributary of the Hadejia River .
Gombe , usually referred to as Gombe State to distinguish it from the city of Gombe , is located in the northeastern part of Nigeria , is one of the country 's 36 states ; its capital is Gombe . The boundaries of the state roughly correspond to those of the Tangale-Waja Chiefdom and Gombe Emirate , a traditional state .
The Dadin Kowa Dam is in Yamaltu local government area of Gombe State in the north east of Nigeria . The dam is located about 35 kilometers to the east of Gombe town , and provides drinking water for the town . The dam was completed by the federal government in 1984 , with the goal of providing irrigation and electricity for the planned Gongola sugar plantation project .
The Goronyo Dam impounds the Rima River in Goronyo local government area of Sokoto State in the north of Nigeria . It was completed in 1984 and commissioned in 1992 . The dam is a sand-fill structure with a height of 21 m and a total length of 12.5 km . It has a storage capacity of 976 million cubic meters . The dam will be important in controlling floods and releasing water in the dry season for the planned Zauro polder project downstream in Kebbi State . In August 2009 Governor Aliyu Magatakarda Wamakko urged the Federal Government to hasten completion of the irrigation project . The Minority Leader of the Sokoto State House of Assembly , Alhaji Bello Goronyo , said that N4 billion was needed to complete canalisation , but only about N600 million was provided in the 2009 budget . In late August 2010 rainstorms caused the dam to fill to dangerous levels . In an attempt to reduce the risk of failure , the gates were opened on 1 September 2010 , causing major flooding in the downstream village of Kagara . On 8 September the spillway from the dam completely failed , causing much more widespread flooding . The storm that caused the flooding may be part of a climate change pattern , with rising temperatures and more intense rainfall in the rainy season .
The Ikere Gorge Dam is a major earth-fill dam in Iseyin local government area of Oyo State in the south west of Nigeria on the Ogun River . Reservoir capacity is 690 million m3 . The dam was initiated by the military regime of General Olusegun Obasanjo and started in 1983 by the administration of Shehu Shagari . The dam was planned to generate 37.5 MW of electricity , to supply water to local communities and to Lagos and to irrigate 12,000 hectares of land . Built in 1982/1983 , work on the dam was abandoned by subsequent military governments . A report for the UN in 2004 said that no irrigation had taken place so far , but efforts were being made to implement one of the five planned irrigation projects . The project was based on the sprinkler system which is difficult to manage and requires that the farmers be trained .
Niger or Niger State is a state in Central Nigeria and the largest state in the country . The state capital is Minna , and other major cities are Bida , Kontagora , and Suleja . It was formed in 1976 when the then North-Western State was bifurcated into Niger State and Sokoto State . It is home to Ibrahim Babangida and Abdulsalami Abubakar , two of Nigeria 's former military rulers . The Nupe , Gbagyi , Kamuku , Kambari , Dukawa , Hausa and Koro form the majority of numerous indigenous tribes of Niger State . The state is named after the River Niger . Two of Nigeria 's major hydroelectric power stations , the Kainji Dam and Shiroro Dam , are located in Niger State , and the newly Zungeru Dam is also located there , the Jebba Dam is half Niger state and Kwara Sharing bounderies . The famous Gurara Falls is in Niger State , and Gurara Local Government Area is named after the Gurara River , on whose course the fall is situated .

Katsina , usually referred to as Katsina State to distinguish it from the city of Katsina , is a state in North West zone of Nigeria . Its capital is Katsina , and its Governor is Aminu Bello Masari , a member of the All Progressives Congress . Katsina State was carved out of old Kaduna State in 1987 .
The Jibiya Dam is in Jibiya local government area of Katsina State in the north of Nigeria . It is an earth-fill structure with a geomembrane liner , with a height of 23.5 m and a total length of 3,660 m , and has a capacity of 142 million m3 . The dam was designed in 1987 and completed in 1989 , and was built to support irrigation and water supply . The landscape at the dam site is sub-desertic except in the rainy season . The Gada river flows for only about four months each year , with a catchment area at Jibiya of over 400 km2 . Due to the loose sandy nature of the surface soil , a flexible impervious liner was used that could adapt to settling or deformation of the embankment . An assessment of the dam in 2004 rated its condition good but noted that no instrument readings had been made since 1994 due to lack of training of the operators . As of 2007 , the dam was not being used for irrigation due to lack of fuel to run the pumps . The Gada River flows from Nigeria into Niger and then back into Nigeria . In the past , it was dry for eight months of the year . There is now a regulated flow throughout the year , which has improved the water supply in Niger .
