New London dam
New London
New London, located in Kandiyohi County, Minnesota, is home to a significant water resource known as the Crow River Middle Fork. The New London dam, completed in 1864, stands at a height of 20 feet and serves various purposes, with a primary dam type of Earth and a hydraulic height of 5.5 feet. The dam has a high hazard potential but is deemed to be in satisfactory condition as of the last assessment in October 2017.
Managed by the Minnesota Department of Natural Resources, the New London dam is subject to state regulation, permitting, inspection, and enforcement. With a storage capacity of 13,371 acre-feet and a drainage area of 75 square miles, the dam plays a crucial role in water management and flood control in the region. The structure has a spillway width of 13 feet and a maximum discharge of 380 cubic feet per second, ensuring the safety and stability of the surrounding area.
New London's rich history and its vital water infrastructure make it a significant location for water resource and climate enthusiasts. The dam's role in managing the Crow River Middle Fork and its impact on the local ecosystem highlight the importance of sustainable water management practices in the face of changing climate conditions. As the community continues to prioritize water conservation and safety, the New London dam stands as a testament to the intersection of human infrastructure and natural resources in the fight against climate change.

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 New London
Where does the data for New London 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 High 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.
