| Datum Gage + Stage Level = Water Elevation Today | 770.00 Datum Gage + 5.42 Sample Stage Level ——————————————- 775.42 Water Elevation Today |
|
| The Datum Gage is always 770.00. The Stage level varies with water elevations. | ||
| Summer Operating Orders 776.55 Maximum 776.20 Target Level 775.73 Minimum |
Winter Operating Orders 776.00 Maximum 775.27 Crest of Dam 775.50 Minimum |
776.20 Summer Target – 775.95 Water Elevation Today ——————————————– .25 feet Below Target .25 feet = 3 inches |
