Katy's Lake Dam dam
Katy's Lake Dam
Katy's Lake Dam, located in Sheridan, Montana, is a federal-owned structure managed by the Fish and Wildlife Service. Built in 1990, the dam serves as a Fish and Wildlife Pond with a primary purpose of supporting conservation efforts. Designed by USFWS and Ducks Unlimited, this earth dam stands at a height of 10 feet and spans 350 feet in length, providing a storage capacity of 10,560 acre-feet.
Despite its low hazard potential, Katy's Lake Dam has been assessed to be in poor condition as of October 2016. The dam's inspection frequency is every five years, with the last assessment revealing a very high risk rating. While the dam features a controlled spillway and a maximum discharge capacity of 100 cubic feet per second, there are no outlet gates or associated structures mentioned in the data.
Water resource and climate enthusiasts monitoring Katy's Lake Dam should take note of its critical condition assessment and high-risk ranking. As a vital component in supporting wildlife conservation efforts in the area, ensuring the proper maintenance and monitoring of this dam is crucial for its long-term functionality and the protection of surrounding ecosystems. With its unique design and purpose, Katy's Lake Dam continues to play a significant role in the management of water resources in the region, highlighting the importance of sustainable infrastructure practices in the face of changing environmental conditions.

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 Katy's Lake Dam
Where does the data for Katy's Lake Dam 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.
