Sherrill Bill dam
Sherrill Bill
Sherrill Bill is a privately owned earth dam located in Vinson, Oklahoma, built in 1978 by the USDA NRCS. This dam is regulated by the Oklahoma Water Resources Board and is inspected, permitted, and enforced by state agencies. With a height of 25 feet and a length of 347 feet, Sherrill Bill serves a primary purpose of "Other" and has a maximum storage capacity of 50 acre-feet.
Despite its low hazard potential, Sherrill Bill is classified as having a very high risk level, indicating the need for careful monitoring and management. The dam features a controlled spillway and one valve outlet gate. The last inspection of Sherrill Bill was conducted in November 2010, with an inspection frequency of 5 years. The condition of the dam is currently rated as "Not Rated," and it does not have an Emergency Action Plan in place.
For water resource and climate enthusiasts, Sherrill Bill provides a fascinating case study of a privately owned earth dam in Oklahoma. With its unique design and regulatory oversight, this dam offers insight into the complexities of managing water resources in the face of climate change and increasing risk levels. Continued monitoring and maintenance of Sherrill Bill will be crucial to ensure its safety and functionality for years to come.

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 Sherrill Bill
Where does the data for Sherrill Bill 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.
