USGS Water-Year Summary 2023

01567000 JUNIATA RIVER AT NEWPORT, PA

LOCATION - Lat 40°28'42", long 77°07'46" referenced to North American Datum of 1927, Perry County, PA, Hydrologic Unit 02050304, on right bank at downstream side of bridge on State Highway 34 at Newport, and 1,000 ft upstream from Little Buffalo Creek.

DRAINAGE AREA - 3,354 mi².

REVISIONS HISTORY - WSP 756: Drainage area. WSP 781: 1902(M). WSP 1302: 1915-17. WSP 1502: 1899-1908, 1914, 1924, 1936. WSP 1722: 1916.

SURFACE-WATER RECORDS

PERIOD OF RECORD - April 1899 to current year.

GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 363.93 ft above National Geodetic Vertical Datum of 1929. Prior to Jul 16, 1929, non-recording gage at same site and 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. Geological Survey.

REMARKS - Flow regulated since Oct 1972 by Raystown Dam (station 01563100) about 75 mi upstream. Since June 1969, water diverted upstream from station for municipal supply. Records for water years 2014-2016 are good except those for discharges less than 2,000 ft³/s, which are fair and those for estimated daily discharges, which are poor. Records for water years 2017-2019 are good except for discharges less than 2,000 ft³/s, which are fair and for estimated discharge, which is poor. Records for water years 2020-2023 are fair except for estimated discharge, which is poor.

EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Jun 1, 1889, reached a stage of 35.9 ft, from floodmarks, discharge, about 209,000 ft³/s, from rating curve extended above 100,000 ft³/s.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Water years 1944 to 1993, 2008 to current year.

PERIOD OF DAILY RECORD - WATER TEMPERATURE: October 1944 to June 1953, April 1958 to September 1962, October 1964 to September 1993, May 2008 to March 2015. SPECIFIC CONDUCTANCE: October 1964 to June 1993; May 2008 to March 2015. pH: October 1969 to September 1970, October 1972 to September 1973; May 2008 to March 2015. DISSOLVED OXYGEN: May 2008 to March 2015. SUSPENDED-SEDIMENT DISCHARGE: Jan 1951 to June 1993.

COOPERATION - Continuous daily water quality records were collected by the U.S. Geological Survey in cooperation with the Pennsylvania Department of Environmental Protection.

INSTRUMENTATION - Water quality monitor interfaced with a data collection platform with 30-minute recording interval May 2008 through March 2015.

REMARKS - Daily records may be affected at times by intense rainfall coupled with low river stage. At these times, the monitor may not represent general river conditions. Data collection discontinued during fall and winter months from October 2008 to April 2011. All parameters collected year-round since October 2011. Periods of missing record since October 2011 are due to equipment failure. Record qualified but rated according to probe performance. Records for 2014 water year for water temperature and pH are rated good. Dissolved oxygen records rated good except for period June 18 to July 22, which is rated fair. Specific conductance records rated fair. Records for 2015 water year for water temperature is rated good. Specific Conductance, pH, and Dissolved Oxygen are rated fair except for period December 26 to March 27, which are rated poor. As of October 2013, results from discrete water quality samples collected at this site are available through the U.S. Geological Survey National Water Information System web interface on the "Water Quality for the Nation" webpage. Analyses for pH, water temperature, specific conductance, and dissolved oxygen were performed on site. Inorganic sample analyses were performed at the Pennsylvania Department of Environmental Protection laboratory in Harrisburg, Pa. Occasionally, values for filtered parameters may exceed values for the corresponding unfiltered parameter. These results are within the limits of analytical precision and methods.

EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: (Water years 2008 to 2015) Maximum, 34.3°C, July 22, 2011; minimum, 0.0°C, many days. SPECIFIC CONDUCTANCE: (Water years 2008 to 2015) Maximum, 448 micromsiemens/cm, March 14, 2013; minimum, 61 microsiemens/cm, Sep 10, 2011. pH: (Water years 2008 to 2015) Maximum, 9.8, Apr 14, 2012; minimum, 6.7, Sep 28, 2008 and Sep 10, 2011. DISSOLVED OXYGEN: (Water years 2008 to 2015) Maximum, 16.9 mg/L, Nov 14, 2013; minimum 3.2 mg/L, Jul 24, 2011. Extreme daily values for for period of daily record prior to 1994 published in WRD PA-93-2 for the following parameters: SPECIFIC CONDUCTANCE, WATER TEMPERATURE, SUSPENDED-SEDIMENT CONCENTRATIONS, SUSPENDED-SEDIMENT DISCHARGE.
