Lake 40 & 8 Dam dam
Lake 40 & 8 Dam
Lake 40 & 8 Dam, located in Sedgwick County, Kansas, is a private earth dam primarily used for recreation purposes. Standing at a height of 20 feet and stretching for 625 feet in length, this dam boasts a NID storage capacity of 110 acre-feet, with a normal storage level of 80 acre-feet. The structure is situated on Spring Creek-TR, offering a serene and picturesque setting for water resource and climate enthusiasts to explore.
Despite its low hazard potential and not having been state-regulated or inspected since 1997, Lake 40 & 8 Dam remains a popular spot for outdoor activities in the region. With its buttress core type and unknown foundation, the dam provides a safe recreational space for visitors to enjoy fishing, boating, and other water-based activities. While the dam's risk assessment and emergency preparedness measures are currently not rated or specified, the tranquil surroundings and ample storage capacity make it an ideal destination for those seeking a peaceful escape.
In the absence of federal funding, design, construction, regulation, or operations, Lake 40 & 8 Dam stands as a testament to private ownership and stewardship in maintaining water resources for recreational use. Whether you're a local resident or a traveler passing through Oxford, Kansas, this dam offers a unique opportunity to appreciate the beauty of nature while supporting sustainable water management practices.
Dam data reference
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.
Plan around the weather

About Lake 40 & 8 Dam
Where does the data for Lake 40 & 8 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.
