This research is geared towards establishing the link between the need for Nigeria rain gauge network improvement and the low efficiency of the current operating system with their various challenges. Nigeria currently has 87 existing and operating rain gauges while it need extra 970 gauges for proper rainfall measurement and achievement of gauge density of 874 km2 per gauge. According to the World Meteorological Organization guideline, the required number of rain gauges to minimize cost and maximize efficiency for temperate Mediterranean and tropical flat area is in the range of 600-900 km2 per gauge. The impact of not increasing Nigeria existing rain gauges is a 10% increase in error of any design based on the current 87 gauges. The flood devastation of the country in September 2012 due to high rainfall and release of flood water from dams are examples of effect of improper planning arising from no or inaccurate records. Equally of great importance is the negative contribution of such error to our economic development as a nation with failure of existing infrastructure being recorded in our roads, rail lines, air ports, water ways and other water resources infrastructures. Finally, it is noteworthy to observe that these largely man-made problems can be overcome with leadership that is alive to its obligation to the society it governs as we face the challenges of globalization and global climate change.
