In undeveloped and less developed countries of arid zones, the easiest way for water supply is withdrawal of groundwater. The negative perception of this method of water discharge is clear. Floodwater Spreading is one of the water resources management strategies in arid and semi-arid zones that has positive impacts on groundwater resources. The aim of this research is to demonstrate the impact of floodwater spreading on quantity of groundwater in Hashtbandi Plain, minab, Hormozgan province, Iran. Annual changes of water level were determined by reviewing water level of monthly data (2003-2014) of five observation wells. Though the floodwater spreading may not stop the aquifer drop, it has reduced the drop intensity of groundwater level. Results show that the least drop is in observation wells 25 that is near floodwater spreading. The results have shown that before implementing the water spreading project, fluctuation of groundwater levels were proportional to the utilization of groundwater resources, showing a declining rate. After implementing the project, a turning point on groundwater level was observed. However, in the years 2011-2012 due to drought and lack of water filling utilization plan and increased ground water usage, water level has decreased sharply.
