Little Sioux River Bedgrade Control dam
Little Sioux River Bedgrade Control
Located in Harrison County, Iowa, the Little Sioux River Bedgrade Control structure serves as a crucial tool for grade stabilization along the Little Sioux River. Constructed in 1985, this structure stands at a height of 8 feet and spans 170 feet in length, with a storage capacity of 125 acre-feet. With a drainage area of 3538 acres, this structure plays a vital role in managing water flow and preventing erosion in the surrounding area.
Managed by the Iowa Department of Natural Resources, the Little Sioux River Bedgrade Control is regulated and inspected by state authorities to ensure its functionality and safety. Despite being rated as having a low hazard potential and not yet assessed for condition, this structure remains a key component in water resource management in the region. With its primary purpose being grade stabilization, this structure showcases a commitment to sustainable water management practices in Iowa.
Enthusiasts of water resources and climate will appreciate the significance of the Little Sioux River Bedgrade Control in maintaining the ecological balance along the Little Sioux River. As a local government-owned structure, this grade stabilization system exemplifies the collaborative efforts between state agencies and communities to protect water resources and prevent environmental degradation. With its strategic location and design, this structure stands as a testament to the importance of proactive measures in managing water flow and safeguarding against potential hazards in the region.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Little Sioux River Bedgrade Control
Where does the data for Little Sioux River Bedgrade Control come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
