1969 Summary
General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
Zinc Spur Levee is a non-federal, primary levee on the left bank of the Big Wood River, Idaho. Flood Control District No. 9 of Idaho is the sponsor and responsible for operation and maintenance of the levee. The Initial Eligibility Inspection (IEI) Report was completed in February 1988 and subsequently instated into USACE’s Rehabilitation and Inspection Program. The original construction date is unknown. It is about 900 feet long; has an average crown width of about 10 feet; riverside and landside slopes are about 2H:1V; and has an average embankment height of 6 feet.
Performance & Condition
General text description of the historical and anticipated performance of the levee, the people and property benefitting from the levee and who may be at risk of flooding, and actions to address areas of concern.
PLEASE NOTE: The following Risk Characterization is a description of risk associated with this levee system. It is currently undergoing review and may be updated in the future.
The LSOG considers the risk associated with the Zinc Spur levee (LST ID 5218) to be Low (LSAC 4). The embankment has been loaded to a maximum of 80%. The levee is expected to have a high likelihood of poor performance under future flood loads with regard to embankment erosion based on past performance and the current condition of the levee. There is some displaced riprap and levee was damaged in mid-2000. Threatened population is anticipated to be very low. The leveed area would experience shallow inundation allowing for shelter in place; additionally, very short egress out of the leveed area is available.
Flooding Hazard
Historic Loading by Percentage of Height
Representative loading associated with historical flood information as a percentage of the levee height or overtopping.
