The lake is used as a storage reservoir for the Yakima Project, an irrigation project run by the United States Bureau of Reclamation. Although a natural lake, Bumping Lake's capacity and discharge is controlled by '''Bumping Lake Dam''', a {{convert|60|ft|m|adj=on}} high earthfill structure built in 1910 and modified in the 1990s. As a storage reservoir, Bumping Lake's active capacity is {{convert|33,700|acre.ft|e6m3|abbr=unit}}.<ref>[http://www.usbr.gov/dataweb/html/yakima.html Yakima Project] {{webarchive|url=https://web.archive.org/web/20070430182621/http://www.usbr.gov/dataweb/html/yakima.html |date=2007-04-30 }}, United States Bureau of Reclamation.</ref>
