Flood disaster is not a recent phenomenon in Makurdi people in the town have been experiencing its destructive tendencies which are sometimes enormous. Using information sourced from questionnaire, personal observation, and archival records of National Inland Waterways Authority (NIWA) and newspaper reports; this paper examines flood events and its impacts on the people of Makurdi Town. A sample size of 400 respondents was drawn from flood prone areas of the town and the data was analyzed using descriptive statistics and a modified 4-point Likert Scale Rating System. The results of the analyses show that floods in Makurdi occur at the event of high rainfall intensity and mostly between September and October. When flooded, it takes 2-3 days for the flood water to recede depending on the magnitude of event. Apart from rainfall, other factors that influence flooding in the study area included lack of and poor drainage networks, dumping of wastes/refuse in drainage and water channels, and degree of built up areas leading to and increased runoffs. Although, personal properties and public infrastructure suffer all forms of flood damages, residents in the flood prone areas have remained on the basis of having no alternative, cultural ethnic affinity, family home where parent were buried and cheaper houses to rent. Identified flood mitigation measures include river dredging, raising house foundations and building of levees and embankment.
