Parker No.1 dam
Parker No.1
Parker No.1 is a privately owned earth dam located in Ellis, Oklahoma, along the TR-RED BLUFF CR river stream. Constructed in 1962 by the USDA NRCS, this dam stands at a height of 31 feet with a hydraulic height of 27 feet, serving primarily for flood risk reduction purposes. With a storage capacity of 80 acre-feet, the dam covers a surface area of 2 acres and has a controlled spillway width of 1 foot. Despite its low hazard potential, the dam is under state regulation and inspection by the Oklahoma Water Resources Board.
Managed by the Natural Resources Conservation Service, Parker No.1 has a very high risk assessment rating of 1 due to its location and potential impact in the event of a failure. Although the dam's condition has not been rated, regular inspections are conducted every five years to ensure its structural integrity. With a single valve outlet gate, the dam has not been modified in recent years and does not have an Emergency Action Plan prepared. It is crucial for water resource and climate enthusiasts to monitor Parker No.1 closely to mitigate potential risks and ensure the safety of surrounding communities.
Parker No.1's presence in the Tulsa District and its role in flood risk reduction make it a critical infrastructure in Ellis, Oklahoma. As water resource and climate enthusiasts, it is essential to stay informed about the dam's condition, state regulation, and risk assessment to support effective management and maintenance practices. By understanding the dam's design, purpose, and associated risks, enthusiasts can contribute to the preservation of this vital water resource structure and safeguard the local environment from potential hazards.

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 Parker No.1
Where does the data for Parker No.1 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.
