Water Data for the Nation inventory

Monitoring location 01462000 is associated with a Stream in Hunterdon County, New Jersey. Current conditions of Temperature are available. Water data back to 1786 are available online.

The air temperature data for this station are temporary and will only be displayed for 120 days. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
