Effective planning for water resources infrastructures requires accurate and up to date data of the water source. The aim of the research is the optimization of the number of rain gauges required for planning for the volume of water in a watershed which is an absolute necessity for the economic development of the nation. To achieve this, the statistical tolerable error method of non-weighted approach was used to determine the optimum number of rain gauges required for an area that efficiently estimates the rainfall of the watershed. The result obtained indicates that Nigeria require a minimum of 1057 rain gauges to cover its land area of 923300 Km2 and meet the World Meteorological Organisation (WMO) requirement for the Tropical, Mediterranean and Temperate zone. However, Nigeria has 87 existing and operating rain gauge stations presently. This number is grossly inadequate and need to be increased substantially by the opening up of extra 970 stations to meet the minimum requirement of WMO and hence enhance national development through proper water resources planning.
