Floods of May-July 1975 Along the Continental Divide in Montana

Extensive flooding occurred along both sides of the Continental Divide in Montana from May through July 1975. Runoff from above average snowpack at low altitudes combined with runoff from rainfall to cause floods in May. Snowmelt from high altitudes and above average rain in June caused flooding and sustained high flows into July. Federal and State agencies estimated flood damage at about $53,000,000. Peak stages, flow rates, and estimated frequencies were determined for 124 sites.

Annual peak discharges from small drainage areas in Montana through September 1980

Annual peak stage and discharge data have been collected and tabulated for crest-stage gaging sites in Montana. The crest-stage program was begun in July 1955 to investigate the magnitude and frequency of floods from small drainage areas. The program has expanded from 45 crest-stage gaging stations initially to 172 stations maintained in 1980. Data in the report are tabulated for the period of record. (USGS)
