Site 140 dam
Site 140
Site 140, located in Cowley, Kansas, along Stewart Creek, is a local government-owned earth dam with a height of 23 feet and a length of 1760 feet. This dam has a storage capacity of 551 acre-feet and serves the primary purpose of water resource management. With a normal storage capacity of 65 acre-feet and a drainage area of 1.39 square miles, Site 140 plays a crucial role in regulating the flow of water in the region.
Managed by the Kansas Department of Agriculture, Site 140 has a low hazard potential and a moderate risk assessment rating. Although the condition of the dam is currently not rated, it meets state regulatory standards for inspection, permitting, and enforcement. The dam features an uncontrolled spillway with a width of 60 feet, allowing for the safe release of excess water during periods of high discharge. Overall, Site 140 serves as a vital infrastructure for water resource management in the area, ensuring the safety and sustainability of the surrounding ecosystem.
Despite its simple design and construction, Site 140 plays a significant role in maintaining water quality and quantity in Cowley, Kansas. With its strategic location along Stewart Creek and its capacity to store and regulate water flow, this dam contributes to the overall resilience of the region's water resources. As climate change continues to impact water availability and distribution, Site 140 serves as a key asset in adapting to and mitigating the effects of changing climate patterns on water resources in the area.

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 Site 140
Where does the data for Site 140 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.
