About this dam

Waterman-Spring Subwtrshd Site 1

Waterman-Spring Subwtrshd Site 1, located in O'Brien County, Iowa, is a vital water resource managed by the local government with regulatory oversight from the Iowa Department of Natural Resources. Designed by the USDA NRCS in 1961, this earth dam serves multiple purposes including fire protection, stock watering, small fish pond, and flood risk reduction. With a dam height of 29 feet and a length of 502 feet, the reservoir has a storage capacity of 127 acre-feet and covers an area of 10 acres.

Managed by the Natural Resources Conservation Service, this low-hazard dam on TR-DOG CREEK in Cherokee plays a crucial role in water management for the surrounding area. While the condition assessment is not rated, the risk assessment indicates a moderate level of risk. The dam is equipped with an uncontrolled spillway and is inspected regularly to ensure its structural integrity and functionality. Despite its modest size, Waterman-Spring Subwtrshd Site 1 serves as a valuable asset for water supply, agriculture, and environmental protection in the region.

Water enthusiasts and climate advocates can appreciate the importance of Waterman-Spring Subwtrshd Site 1 as a key component of the local water infrastructure. With a focus on sustainable water management and flood risk reduction, this dam exemplifies the intersection of human intervention and natural resources. By maintaining and monitoring this critical structure, the community can ensure the long-term viability of the water resources in O'Brien County, Iowa, and beyond.

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.

FAQ

About Waterman-Spring Subwtrshd Site 1

Where does the data for Waterman-Spring Subwtrshd Site 1 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.
