PERIOD OF RECORD.--October 1913 to March 1936, October 1938 to current year.  Monthly discharge only for some
   periods, published in WSP 1305.  Monthly figures adjusted for storage and diversion for October 1918 to
   September 1921, published in WSP 503, 523, have been found in error and should not be used.  Published as "at
   Johnstown" 1914-36, and as "Stony Creek at Ferndale" 1938-79.  Gage-height records collected in this vicinity
   since 1885 are contained in reports of U.S. Weather Bureau.

REVISED RECORDS.--WSP 743:   Drainage area.  WSP 1305:   1915, 1918, 1923-26.  WSP 1435:   1920-21, 1932,
   1941 (M), 1943 (M), 1945-46 (M).  WDR PA-78-3:   1977 (M).  See also PERIOD OF RECORD.

GAGE.--Water-stage recorder.  Datum of gage is 1,184.06 ft above sea level.  Prior to Mar. 19, 1936, nonrecording
   gage at site 3.5 mi downstream at different datum.  Dec. 8, 1938 to Jan. 30, 1940, nonrecording gage at site
   50 ft downstream at present datum.

REMARKS.--Records good except for estimated daily discharges, which are fair.  Regulation by mine pumpage and
   reservoirs and diversion above station; the four largest reservoirs have a combined capacity of 42,360 acre-ft.
   Figures of daily discharge do not include diversion from Stonycreek River and Quemahoning Creek Reservoir to
   plants of Bethlehem Steel Co., and from Mill Creek, Dalton Run, and North Fork Bens Creek Reservoirs for water
   supply of city of Johnstown.  Several measurements of water temperature were made during the year.  U.S. Army
   Corps of Engineers satellite telemeter at station.
