As the water level in the Columbia River climbs, here is what you can expect.
- 12-feet: Bank Full Level
Water flows along its normal banks and is well below the top of the levee.
- 13.5-feet: Flood Stage
The water level is still below the levee but CDID #1 begins to monitor the river more closely. Expect minor flooding of farmland and low-lying areas not protected by levees
- 15-feet: Moderate Flood Stage
The risk of flood potential is increasing and CDID #1 increases its effort to monitor both the river and the levee conditions.
- 18-feet: Major Flood Stage
Expect major and widespread flowing of unleveed lowlands in and near Longview.
The lowest elevation on CDID #1’s Columbia River levee is approximately 28-feet in the area of Barlow Point.
