Scs-Maysville Laterals Site-H07 dam
Scs-Maysville Laterals Site-H07
Located in Garvin County, Oklahoma, the SCS-Maysville Laterals Site-H07 is a state-regulated earth dam with a primary purpose of flood risk reduction. Built in 1972 by the USDA NRCS, this structure stands at 30 feet high and spans 1690 feet in length, with a storage capacity of 285 acre-feet. The dam is situated on the TR-Happy Hollow Creek within the Tulsa District, providing essential protection to the surrounding community from potential flooding events.
Despite its low hazard potential, the SCS-Maysville Laterals Site-H07 remains a critical infrastructure for flood control in the region. With its controlled spillway and one outlet valve, the dam has a maximum discharge capacity of 410 cubic feet per second. Although last inspected in 1980, the structure is deemed to be in good condition and has not been rated for its current state. However, with a very high risk assessment ranking, it is essential for the regulatory agency, OWRB, to continue regular inspections and maintenance to ensure the dam's effectiveness in mitigating flood risks for the area.
For water resource and climate enthusiasts, the SCS-Maysville Laterals Site-H07 presents an intriguing case study in dam engineering and flood risk management. As a vital piece of infrastructure in Garvin County, Oklahoma, this earth dam serves as a key defense against potential inundation from the TR-Happy Hollow Creek. With its historical significance dating back to 1972, the dam's structural integrity and operational efficiency are crucial factors in safeguarding the local community and surrounding areas from the impacts of flooding.

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 Scs-Maysville Laterals Site-H07
Where does the data for Scs-Maysville Laterals Site-H07 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.
