[!] During cold weather, stage and discharge values may be affected by ice at some streamgages. Streamgages experiencing ice conditions will have the discharge record temporarily disabled to prevent the display of erroneous discharge values. Display of discharge record will resume when it is determined that ice conditions are no longer present. Adjustment of data affected by ice can only be done after detailed analysis.

Station gage imageSTATION.--01453000 LEHIGH RIVER AT BETHLEHEM, PA
LOCATION.--Lat 40`36'55", long 75`22'45", Lehigh County, Hydrologic Unit 02040106, on left bank 110 ft upstream from bridge on New Street at Bethlehem, and 1,800 ft upstream from Monocacy Creek. Records include flow of Monocacy Creek.
DRAINAGE AREA.--1,279 square miles (includes that of Monocacy Creek). At site used prior to Oct. 1, 1928, 1,229 square miles.
PERIOD OF RECORD.--October 1902 to January 1905, May 1909 to current year. Monthly discharge only for some periods, published in WSP 1302. Published as "at South Bethlehem" prior to October 1913.
GAGE.--Water-stage recorder, crest-stage gage, and heated tipping bucket precipitation gage. Datum of gage is 210.94 ft above National Geodetic Vertical Datum of 1929. Prior to October 1928, non-recording gage at New Street bridge 120 ft downstream at same datum. Oct. 1, 1928, to Sept. 30, 1962, water-stage recorder at site 4,250 ft downstream at datum 2.49 ft lower. Oct. 1, 1963, to Dec. 14, 1975, water-stage recorder at site 40 ft downstream at same datum. Satellite and landline telemetry at station.
COOPERATION.--Station established and maintained by the U.S. Geological Survey. Funding for the operation of this station is provided by the U.S. Army Corps of Engineers, Philadelphia District, the Pennsylvania Department of Environmental Protection and the U.S. Geological Survey.
The 15-minute precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a 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.

Supplied by USGS: Maximum recordable gage height (stage sensor operational limit) - 25.7 ft; Data transmitter operational limit - 26.5 ft;
Supplied by NWS: Action stage-12 ft, at 14 ft, flooding begins upstream in Allentown; backwater affects Little Lehigh and Jordan Creeks; Flood stage-16 ft, Wilson Avenue takes on water; Moderate flood stage-20 ft; Major flood stage-22 ft, at 25 ft, levees in Bethlehem are topped.
This station managed by the PAWSC New Cumberland Office.
