Continuously recorded gage heights for the past 30 days are compared to daily (mean) gage heights from last year, the FY2000 water level schedule for Lake Okeechobee, and daily levels for the 2001 drought year.

Description of information presented in the current 30-day hydrograph at HILLSBORO CA AT S6 (02281200)
The change in daily gage height elevations has not been mathematically correlated to time for the period of record based on operational considerations. Instead of a long-term trend line, the data are, therefore, compared to the zero-slope (flat, linear) regression curve for the existing period of record daily gage height elevations. This approximates, but may not equal, the period of record mean. (Description of statistical methods)

Continuously recorded gage heights for the past 90 days are compared to daily (mean) gage heights from last year, the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record, and daily levels for the 2001 drought year.
