Dane Ridge Watershed Site D-6 dam
Dane Ridge Watershed Site D-6
Dane Ridge Watershed Site D-6 is a key water resource in Crawford, Iowa, managed by local government authorities with oversight from the Iowa Department of Natural Resources. Built in 1978 by the USDA NRCS, this earth dam stands at 31 feet tall and spans 450 feet, offering fire protection and stock watering facilities while also serving as a small fish pond. With a storage capacity of 240 acre-feet and a surface area of 6.8 acres, this dam plays a crucial role in flood risk reduction for the surrounding area.
The dam at Dane Ridge Watershed Site D-6 has a low hazard potential and a moderate risk level, according to assessments. While it is not currently rated for condition, regular state inspections and enforcement ensure its safety and integrity. The dam's uncontrolled spillway and soil foundation indicate a simple yet effective design for managing water flow. With its location along the TR-Welsh Creek Gully D-13, this site is a vital component in the local water management infrastructure, contributing to the overall health and sustainability of the watershed.
As a focal point for water resource and climate enthusiasts, Dane Ridge Watershed Site D-6 offers a glimpse into the intersection of human infrastructure and natural ecosystems. With its primary purpose of fire protection and stock watering, the dam provides essential services to the community while also supporting biodiversity through its role as a small fish pond. The site's history of construction and ongoing management by state and federal agencies underscores the importance of proactive stewardship in ensuring the long-term viability of water resources in the region.

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 Dane Ridge Watershed Site D-6
Where does the data for Dane Ridge Watershed Site D-6 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.
