Talawanda No. 1 dam
Talawanda No. 1
Talawanda No. 1 is a historic dam in Pittsburg, Oklahoma, built in 1902 for the primary purpose of water supply. This stone dam stands at a height of 38 feet and spans 700 feet in length, with a storage capacity of 1578 acre-feet. Situated on the TR-COAL CR river, this dam has been under the regulatory jurisdiction of the Oklahoma Water Resources Board, ensuring state permitting, inspection, and enforcement for its operations.
Despite being rated as having low hazard potential, Talawanda No. 1 poses a very high risk due to its age and condition assessment being not rated. With a controlled spillway and only one outlet valve, emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps have not been prepared or updated. The dam's risk management measures remain unspecified, leaving room for improvement in mitigating potential risks and ensuring the safety of the surrounding community in Shady Grove.
Overall, Talawanda No. 1 serves as a vital water supply infrastructure in Oklahoma, but its risk assessment and management could benefit from further attention and updates to enhance its resilience and safety in the face of changing climate conditions. Water resource and climate enthusiasts may find interest in the historical significance and potential vulnerabilities of this dam, highlighting the importance of proactive risk assessment and emergency preparedness for critical infrastructure like Talawanda No. 1.

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 Talawanda No. 1
Where does the data for Talawanda 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.
