DRAINAGE AREA.--3,810 mi2, approximately, including 26.2 mi2 in closed basin of Crater Lake.
PERIOD OF RECORD.--May 1904 to September 1922 (gage heights only), October 1922 to current 
   year. Monthend contents only October 1923 to September 1927, published in WSP 1315-B.
GAGE.--Water-stage recorder. Datum of gage is 4,098.22 ft above NGVD of 1929, or 4,100.00 ft 
   above Bureau of Reclamation datum. Gage readings have been reduced to elevations above Bureau 
   of Reclamation datum. See WSP 1735 for history of changes prior to Nov. 10, 1923. Since 
   Oct. 1, 1974, supplementary water-stage recorders at sites 7 mi north and 21 mi northwest at 
   same datum (water-surface transfer by Pacific Power and Light Co.).
REMARKS.--Reservoir is formed by concrete dam at outlet of natural lake, completed in 
   1921, replacing a temporary dam built in 1919; controlled storage began Apr. 15, 1919. 
   Capacity, 523,700 acre-ft between elevations 4,136.0 ft and 4,143.3 ft. Dead storage below 
   elevation 4,136.0 ft is 211,300 acre-ft. Stored water may be diverted through "A" Canal for

   for last 3 days of month and first 3 days of following month to compensate for wind effect. 
   Since Oct. 1, 1974, daily elevations are weighted mean of elevations at base and supplementary 
   gages; contents at end of month are obtained from weighted midnight elevations of base and 
   supplementary gages.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 4,144.98 ft about Apr. 20, 1904, from
