Brock Dam dam
Brock Dam
Located in Adams County, Iowa, Brock Dam is a privately owned earth dam primarily used for fire protection and as a stock or small fish pond. Built in 1993 by the Soil Conservation Service, this dam stands at a height of 23 feet and stretches 587 feet in length, with a storage capacity of 130 acre-feet. The dam is situated on TR-Kemp Creek in the city of Lake Icaria, serving as a vital resource for the local community.
Managed and regulated by the Iowa Department of Natural Resources, Brock Dam is classified as having a low hazard potential and a moderate risk level. While its condition remains unrated, the dam is regularly inspected and meets state permitting and enforcement requirements. The dam's purpose, along with its design and construction by the SCS, highlights its significance in providing essential water resources for fire protection and recreational activities in the region.
With its strategic location and function, Brock Dam plays a crucial role in maintaining water security and environmental sustainability in the area. As a key feature in the landscape, the dam not only serves practical purposes but also contributes to the overall ecosystem health and climate resilience of Adams County. Water resource and climate enthusiasts can appreciate the unique characteristics and importance of Brock Dam in safeguarding water quality and promoting biodiversity within 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 Brock Dam
Where does the data for Brock 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.
