Jewett Wma 1 dam
Jewett Wma 1
Jewett WMA 1 is a state-owned fish and wildlife pond located in Kimberly, Minnesota. The dam, completed in 1979, stands at a height of 9 feet with a length of 675 feet, providing a storage capacity of 700 acre-feet and a surface area of 20 acres. The primary purpose of the dam is to support fish and wildlife activities, with a low hazard potential and a satisfactory condition assessment as of the last inspection in October 2012.
Managed by the Minnesota Department of Natural Resources, Jewett WMA 1 is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. The dam is designed as a rockfill structure with a buttress core type, serving as a controlled spillway for the dam brook. Despite its low hazard potential, the risk assessment for Jewett WMA 1 is rated as very high, indicating the importance of ongoing monitoring and risk management measures to mitigate potential issues.
Located in Aitkin County, Jewett WMA 1 is situated in a scenic area with a drainage area of 11 square miles and a maximum discharge capacity of 100 cubic feet per second. With its important role in supporting local wildlife and recreational activities, Jewett WMA 1 serves as a valuable resource for water and climate enthusiasts interested in the management and conservation of natural habitats in Minnesota.

About Jewett Wma 1
Where does the data for Jewett Wma 1 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 below 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.

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.
