From the Abstract: "Up to 19.19 inches of rain were recorded in southern Maine from October 20-22, 1996. This rainfall caused severe flooding that resulted in one death, damage to more than 2,100 homes and businesses, and the destruction of bridges and dams in 8 communities. Peak flows, with estimated recurrence intervals of greater than 500 years, were recorded on 3 streams. The peak flow on the Presumpscot River in Westbrook, Maine was 68 percent larger than any other flow at that location in the last 102 years. This report provides a detailed description of the October 1996 flood in southern Maine. It presents peak streamflows for 13 sites, peak-flow recurrence intervals for 12 of these 13 sites, and peak water-surface elevations for 74 sites; describes hydrologic conditions prior to the October 20-22 storm; provides a method for estimating the recurrence intervals of peak flows at sites where peak flows were not determined (for this flood); and reports a significant amount of historical flood data for the Presumpscot River."
