Leche M dam
Leche M
Leche M is a privately owned earth dam located in Kay County, Oklahoma, specifically in the city of Kaw City. Built in 1950, this dam stands at a height of 32 feet and has a hydraulic height of 30 feet, with a total length of 400 feet. It serves the primary purpose of "Other" and has a maximum storage capacity of 160 acre-feet, with a normal storage capacity of 75 acre-feet. The dam is regulated, permitted, inspected, and enforced by the Oklahoma Water Resources Board (OWRB), ensuring its safety and compliance with state regulations.
The dam is situated on the TR-Coon Creek and is part of the Tulsa District of the US Army Corps of Engineers. It has a controlled spillway and one valve outlet gate. Despite its low hazard potential, Leche M is classified as having a very high risk due to its condition assessment being "Not Rated." The last inspection was conducted in May 2011, with an inspection frequency of every five years. The dam lacks an emergency action plan (EAP) and inundation maps, highlighting the need for improved risk management measures to address potential hazards.
For water resource and climate enthusiasts, Leche M presents an intriguing case study of a privately owned dam in Oklahoma with a unique design and purpose. Its location in a high-risk area underscores the importance of regular inspections and emergency preparedness measures. As the dam continues to be monitored by the OWRB and other regulatory agencies, there is an opportunity for stakeholders to collaborate on implementing risk management strategies to enhance the safety and resilience of this critical infrastructure.

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 Leche M
Where does the data for Leche M 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.
