Historical dates of ice-affected flows for 18 rivers in New England were compiled and are presented in this report. The length of this record for the rivers ranges from 48 to 71 years, with an average of 62 years. The minimum number of days of ice-affected flow in a water year October 1 to September 30 ranged from zero on three rivers in south-coastal Maine and coastal New Hampshire to 110 on the Allagash River in northern Maine. The maximum number of days of ice-affected flow in a water year ranged from 106 on the Royal River in south-coastal Maine to 171 on the Allagash River in northern Maine. Six streamflow- gaging stations in Maine, New Hampshire, and Vermont had their latest days of ice-affected flow in the spring of 1939. Reports and their predecessor Water-Supply Papers, for States in New England and files. This report, prepared as part of the USGS Global Change Hydrology Program, makes these data easily available to researchers and other interested parties. This report would not have been possible without the collection, compilation, and archiving of river ice and flow data by many USGS hydrologic technicians and hydrologists over the past century, often under hazardous conditions. Glenn Smith and other USGS employees in Maine and New Hampshire compiled most of the data used in this report.
