A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration and divert stormwater from city sewers. These input data were collected from a rain gage ((USGS site 413611087201301, City Hall Weather Station at Gary, IN.) and five monitoring wells with installed pressure transducers at different locations (see site description). The Episodic Master Recession (EMR) method is applied using these data as the singular input to estimate the amount of groundwater recharge at each of the five sites during the indicated period of time.
