Current Stream Flow Conditions In New Hampshire

The United States Geological Survey (USGS) maintains gaging stations on many of the rivers, streams, creeks and lakes around New Hampshire. From these stations, current stream flow conditions are transmitted every few hours via satellite into USGS district computer systems and from there onto the Internet. This data should be considered PROVISIONAL in nature. What does this mean? Well, it means that this data may be significantly inaccurate due to any of the following causes: backwater from ice or debris such as log jams; algal and aquatic growth in the stream; sediment movement; or malfunction of recording equipment. All data will subsequently be reviewed and could possibly be changed by the USGS, usually within 6 months of the end of the water year.

The USGS strongly cautions any users of this information to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. You should always visually inspect a river, stream or creek for yourself, prior to beginning a float trip, to determine whether current stream flow conditions are adequete and safe.
