PERIOD OF RECORD.--
March 1991 to April 1992, April 2003 to
Water-stage recorder--15 minute; periodic manual
measurements by USGS personnel.
Due to unknown causes, the water level dropped about 7
ft between September 23 and October 2, 2005, and then rose over 23 ft
between October 2 and November 23, 2005. After leveling off by January
1, 2006, there is an unexplainable 9 ft shift in water level. Extremes
are reported for the periods of record before and after this resulting
water-level shift. The period September 23 (1300) through December 31,
2005, was deemed questionable record and therefore disregarded.
Satellite water-level telemeter at station.
