Ice jams are accumulations of ice in rivers that restrict water flow. Ice jams can cause destructive floods that are costly to riverine communities. Areas below the ice jam can also be affected when the jam releases, sending water and ice downstream. The rapid increase in water levels associated wit...

Description
Summary:Ice jams are accumulations of ice in rivers that restrict water flow. Ice jams can cause destructive floods that are costly to riverine communities. Areas below the ice jam can also be affected when the jam releases, sending water and ice downstream. The rapid increase in water levels associated with jams often leaves little time to prepare for flooding. Damages caused by ice jams can be great, affecting roads, bridges, buildings, and homes. Accurate and reliable ice jam data are essential to the work of engineers in preventing and alleviating the damages caused by ice jams. The Cold Regions Research and Engineering Laboratory (CRREL) Ice Jam Database is a compilation of freezeup and breakup ice jam events in the United States. Currently there are nearly 12,000 records in the database, with the earliest account dating from 1780. For each ice jam event, the database provides the river name, city, state, jam date, jam type, damages, a short description, a listing of publications, latitude and longitude, U.S. Geological Survey hydrological unit code, and USGS gage number, if available. Many entries rely on annual USGS Water Resources reports (USGS 1999) and other USGS gaging station data. Information also comes from newspapers, books, historical records, trip reports, and other historical accounts of ice jams. The Ice Jam Database is a useful tool in characterizing ice jams for specific areas and for providing information during emergency ice jam flood situations.
