Harvey Dam dam
Harvey Dam
Harvey Dam, located in Lockridge, Iowa, is a privately owned structure designed by USDA NRCS for grade stabilization purposes. Completed in 2006, this earth dam stands at a height of 26 feet and spans a length of 310 feet, with a storage capacity of 40 acre-feet. Situated on a tributary to Wolf Creek, the dam plays a crucial role in managing water resources and preventing erosion in the area.
With a low hazard potential and not yet rated for condition assessment, Harvey Dam serves as a vital infrastructure for water management in Jefferson County, Iowa. Despite its modest size, the dam's impact on the local hydrology is significant, with a maximum discharge capacity of 131 cubic feet per second. As a key component of the local water resource system, the dam contributes to the overall sustainability and resilience of the region's water supply and climate adaptation efforts.
As water resource and climate enthusiasts, the intricate details of Harvey Dam's design, construction, and operational characteristics offer valuable insights into the complexities of managing water infrastructure. With its state permitting and inspection compliance, the dam exemplifies best practices in infrastructure governance and underscores the importance of effective water resource management in mitigating climate-related risks and ensuring long-term water security for the community.

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 Harvey Dam
Where does the data for Harvey 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.
