Rolling Hills Estate Dam - Jones County dam
Rolling Hills Estate Dam - Jones County
Located in Jones County, Iowa, the Rolling Hills Estate Dam is a private-owned earth dam that was completed in 2006 by MMS Consultants. Situated in Anamosa, the dam serves as a recreational spot along a tributary to the Wapsipinicon River, offering a serene getaway for water resource and climate enthusiasts. With a height of 30 feet and a length of 430 feet, the dam has a storage capacity of 90 acre-feet and covers a surface area of 5.9 acres.
Managed by the Iowa Department of Natural Resources, the Rolling Hills Estate Dam is deemed to have a low hazard potential and is currently in a not rated condition. The dam's primary purpose is for recreation, providing locals and visitors with a tranquil environment to enjoy outdoor activities. While the dam is regularly inspected and permitted by the state regulatory agency, emergency preparedness measures such as an Emergency Action Plan are not yet in place.
Jones County residents can appreciate the beauty and functionality of the Rolling Hills Estate Dam, knowing that it enhances the local landscape and offers a safe recreational space for all to enjoy. With its strategic location and modest size, the dam stands as a testament to the importance of water resource management and the positive impact it can have on communities and ecosystems.

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 Rolling Hills Estate Dam - Jones County
Where does the data for Rolling Hills Estate Dam - Jones County 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.
