The Gainsborough Creek forms most of the southern boundary of the town, while the rest of the community is bordered by open fields and pasture. A tributary of the Souris River, the creek is prone to flooding during the spring thaw. Though several nearby communities made national headlines as disaster areas during severe flooding in 2011, most buildings in Gainsborough did not require unusual extraordinary protection measures or sandbagging. In 2014, extended heavy rainfall in the region resulted in severe flash flooding that forced the complete evacuation of residents to neighbouring communities and made national headlines. Provincial premier Brad Wall did an aerial survey of the flood area that allowed images and video of the flooded village to be recorded near the maximum height of the waters.
