Description of information presented in the current 30-day hydrograph at IMPERIAL RIVER (02291500)
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)
