Topic Flow: Annual Peaks - Kootenai River at Leonia, ID - 1929-2001
Caption:  This chart displays annual peak discharge measured at Leonia, ID between 1928 and 2001. Annual peak flows are observed between April and June prior to the construction of the Libby dam in 1992. After dam construction, annual peak flows decrease in magnitude and occur during late fall and in winter months. Flow mitigation after 1991 attempts to re-establish peak flow magnitudes and re-time annual peaks to the summer months (Paragamian, et al, 2001) show as a somewhat increased flow regime. Annual peaks were measures at USGS gage # 12305000. See Info Links for more Information.
