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. In order to investigate the impacts of the installed SCMs, hydrologic data were collected prior to and following the installation to estimate site water budgets (Lampe and others, 2022). The Episodic Master Recession (EMR) method was used to estimate recharge rates at five different locations for inclusion in the site water budgets (Heppner and Nimmo, 2005; Nimmo and others, 2015). Input data for the EMR software package were collected from a rain gage and five monitoring wells with installed pressure transducers at different locations (see site description). The method output includes a descriptive text file, two hydrographs and a csv file for each site and year of data.
