LOCATION.--Lat 44° 54'13", long 116° 02'29"(Rev.)(NAD83), in NW1/4 NW1/4 sec.13, T.18 N., R.3 E., Valley County, McCall quad., Hydrologic Unit 17050123, at outlet gate near center of dam on Lake Fork Payette River, 3 mi east of McCall, and at mile 18.0.

DRAINAGE AREA.--59.0 mi², revised.

PERIOD OF RECORD.--April 1926 to September 1973 (fragmentary) (discontinued).

GAGE.--Nonrecording gage on concrete gate-control structure of dam. Datum of gage is at mean sea level (levels by Lake Irrigation District).

REMARKS.--Reservoir is formed by earth- and rock-fill dam completed in 1926. Capacity, 16,940 acre-ft between elevations 5,101.0 ft (lower limit of capacity table, 4.0 ft above gate sill of outlet) and 5,117.0 ft (top of flashboards, 5.0 ft above spillway crest). Dead storage unknown. Water is used for irrigation of about 6,800 acres of land near McCall and Norwood. There is some usable storage below elevation 5,101.0 ft, but natural flow passing through reservoir when outlet gates are open prevents withdrawal of storage to elevation of sill of gates. No observations were reported below 5,101.0 ft during the reporting period.

EXTREMES FOR PERIOD OF RECORD.--Maximum contents observed, 21,060 acre-ft, June 21, 1961, elevation 5,119.56 ft; no storage above elevation 5,101.0 ft for long periods during fall and winter of most years. Minimum elevation observed below 5,101.0 ft, 5,099.04 ft, Dec. 9, 1936.
