Crawford Dam dam
Crawford Dam
Crawford Dam, located in Coppock, Iowa, is a privately owned earth dam completed in 2001 for grade stabilization purposes along Tr- Dutch Creek. Designed by the USDA NRCS, the dam stands at 27 feet high and spans 300 feet in length, with a storage capacity of 22 acre-feet. Despite its modest size, the dam plays a crucial role in managing the flow of water in the area, with a low hazard potential and a moderate risk assessment rating.
The dam features an uncontrolled spillway and is not regulated or inspected by the state, highlighting its private ownership and operation. While it has not been rated for its condition, the dam serves its purpose effectively in stabilizing grades and managing water levels in the surrounding areas. With a surface area of 2 acres and a drainage area of 0.09 square miles, Crawford Dam contributes to the overall water resource management in Washington County and provides important insights for water resource and climate enthusiasts interested in sustainable infrastructure development.
As a part of the Rock Island District, Crawford Dam is a testament to the collaborative efforts between private owners and federal agencies like the Natural Resources Conservation Service. With its strategic location and function, the dam not only serves practical purposes but also serves as a valuable case study for those interested in the intersection of water resource management, climate resilience, and infrastructure development.

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 Crawford Dam
Where does the data for Crawford Dam 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.
