Clark Subwatershed Gully 7 Sta70+00 dam
Clark Subwatershed Gully 7 Sta70+00
Located in Quimby, Iowa, the Clark Subwatershed Gully 7 Sta70+00 is a vital structure managed by the local government for fire protection, stock, and small fish pond purposes. Built in 1956 by the USDA NRCS, this earth dam stands at a height of 37 feet and has a storage capacity of 62 acre-feet, serving as a key component in flood risk reduction efforts in the area. With a low hazard potential and moderate risk assessment rating, the dam plays a crucial role in water resource management along the TR-Little Sioux River.
The Clark Subwatershed Gully 7 Sta70+00 dam, with a surface area of 1.1 acres and a drainage area of 0.25 square miles, is regulated by the state of Iowa through the Iowa DNR. Despite not being currently rated for condition assessment, the dam's structural integrity is regularly inspected, meeting state permitting and enforcement requirements. Additionally, the dam is not under the jurisdiction of the USACE but falls under the responsibility of the local government for operations and maintenance.
As part of the larger Rock Island District, the Clark Subwatershed Gully 7 Sta70+00 dam contributes to the overall water management strategy in Cherokee, Iowa. Its strategic location and design by the USDA NRCS highlight the collaborative efforts between federal and local agencies to ensure the safety and sustainability of water resources in the region. Climate and water resource enthusiasts will find this structure an intriguing example of integrated watershed management practices in action.
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.

About Clark Subwatershed Gully 7 Sta70+00
Where does the data for Clark Subwatershed Gully 7 Sta70+00 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.
