Godfrey Dam dam
Godfrey Dam
Godfrey Dam, located in Marshall County, Iowa, is a privately owned structure designed by the Soil Conservation Service (SCS) with a primary purpose of providing fire protection, stock, or serving as a small fish pond. Completed in 1992, this earth dam stands at a height of 22 feet and spans 565 feet in length, holding a maximum storage capacity of 161 acre-feet. The dam is regulated by the Iowa Department of Natural Resources (DNR) and is subject to state permitting, inspection, and enforcement.
The dam, situated on TR-Snipe Creek, has a low hazard potential and a moderate risk assessment rating of 3. Despite its low hazard potential, the condition assessment of the dam is currently unrated. The dam does not have an Emergency Action Plan (EAP) in place, and there is no information available regarding the last inspection date or inspection frequency. Considering the critical role of water resources in the face of climate change, the maintenance and management of Godfrey Dam will be crucial to ensuring the safety and sustainability of the surrounding area.
As climate change continues to impact water resources and infrastructure, the importance of maintaining and monitoring dams like Godfrey Dam cannot be understated. With its key role in fire protection and water storage, the dam serves as a vital resource for the community of Kellogg, Iowa. It is imperative that regular inspections, risk assessments, and emergency preparedness measures are implemented to mitigate any potential threats and ensure the long-term resilience of Godfrey Dam in the face of a changing climate.

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 Godfrey Dam
Where does the data for Godfrey 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.
