Little Waverly Lake dam
Little Waverly Lake
Little Waverly Lake in Wright, Minnesota is a state-owned reservoir with a gravity dam completed in 1938 by the Works Progress Administration - Civil (WPA-C). The dam stands at 7 feet tall and has a hydraulic height of 4.7 feet, creating a storage capacity of 2,780 acre-feet and a surface area of 330 acres. The reservoir is situated on the Twelvemile Creek and serves various purposes, with a maximum discharge capacity of 3,080 cubic feet per second.
Managed by the Minnesota Department of Natural Resources, Little Waverly Lake has been regulated, permitted, inspected, and enforced for safety and environmental compliance. The dam is classified as low hazard potential and was deemed to be in satisfactory condition as of the last assessment in October 2015. The surrounding area is protected by state jurisdiction, ensuring proper management and emergency preparedness, although specific details on risk assessment and management measures are yet to be documented.
With its picturesque location and vital role in water resource management, Little Waverly Lake offers a glimpse into Minnesota's commitment to sustainable infrastructure. Whether exploring the historic dam or enjoying the recreational opportunities provided by the reservoir, water resource and climate enthusiasts can appreciate the careful planning and maintenance that go into preserving this essential piece of the state's natural landscape.

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 Little Waverly Lake
Where does the data for Little Waverly Lake 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.
