Bear Lake dam
Bear Lake
Bear Lake, also known as Little Kaw Creek Detention Dam, is a private water resource in Kansas, specifically located in Leavenworth County. Managed by the USDA NRCS, this Earth dam stands at a height of 41 feet and serves the primary purpose of flood risk reduction along the Kaw Creek-TR river or stream. With a normal storage capacity of 610.7 acre-feet and a maximum discharge of 4620 cubic feet per second, Bear Lake plays a crucial role in managing water flow in the region.
This dam, with a structural height of 48 feet and a length of 900 feet, has a high hazard potential but is currently assessed to be in fair condition. Despite being privately owned, it is subject to state regulation and inspection by the Kansas Department of Agriculture. The last inspection date was in December 2017, with a frequency of every 3 years. While the dam does not have outlet gates or associated structures, it serves as a vital asset for flood control and water management in the area, contributing to the overall resilience of the local water resources and climate.
Bear Lake's strategic location in Mahon, Kansas, and its significant storage capacity of 1738.1 acre-feet make it a key infrastructure for mitigating flood risks and ensuring water security in the region. With its hydraulic height of 39 feet and surface area of 63.1 acres, the dam plays a critical role in regulating water levels and protecting downstream communities. As climate change continues to impact water resources, Bear Lake stands as a vital asset for maintaining the balance between water supply, flood control, and environmental sustainability in Leavenworth County.

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 Bear Lake
Where does the data for Bear 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 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.
