Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
16000 Or 13.3 feet, major flooding will occur near the river in Boise, Garden City, Eagle, Star, and Caldwell. Some residential areas in low lying areas near the river will be flooded with water entering some houses. A flood of this magnitude has not occurred on the Boise River since 1943. Most of the area within the 100 year flood plain, including many city parks near the river, will be underwater. Debris piling up on bridge crossings will cause additional flood damage.
12000 Or 12.5 feet, flooding will occur in low areas and parkland adjacent to the river in Boise, Garden City, Eagle, Star, and Caldwell. Flooding of low lying residential streets in areas adjacent to the river is likely, especially on portions of Eagle Island. Debris damming on bridges crossing the river will occur and may cause water to spill over the road surfaces leading up to the bridge. Park Center Boulevard in southeast Boise will be flooded near the Park Center Pond.
10500 Or 12.0 feet, flooding over Park Center Boulevard in southeast Boise near the Park Center Pond will occur. Flooding near the river will occur in low areas of Boise, Garden City, Eagle, Star and Caldwell. Portions of Eagle Island will be submerged with flooding of residential property in low lying areas near the river likely. The water should remain below the level of most residential structures, but access in and out of some neighborhoods may be limited by high water.
9500 Or 11.5 feet, moderate flooding of low areas near the river in Boise, Garden City, Eagle, Star, and Caldwell will occur. Debris in the river will collect on bridges crossing the river. Water will cover portions of Warm Springs Golf Course and Municipal Park in east Boise. The water may affect some residential property near the river, but should stay below the level of most residential structures.
8900 Or 11.2 feet, large sections of the green belt will be submerged and severe bank erosion will occur. Flooding will occur in low areas close to the river in Boise, Garden City, Eagle and Caldwell, but the water should remain below the level of most residential areas. The river will spill over its banks between 45th and 46th Street in Garden City into the warehouse district.
7000 Or 10.2 feet, large sections of the greenbelt path adjacent to the river will be submerged. Erosion of river banks will also become a significant problem. Debris in the river including small trees and logs may begin piling up at bridge crossings. Minor flooding will be observed on sections of Eagle Island and in other low spots near the river. Minor flooding will spread downstream to low areas near the river in Star and Caldwell.
6500 Or 9.9 feet, large sections of the greenbelt path adjacent to the river will be submerged. Minor flooding may affect portions of Eagle Island.
4000 Or 8.5 feet, water will begin seeping onto low spots on the greenbelt path next to the river especially near bridge underpasses.
