Lake Massena dam
Lake Massena
Lake Massena, also known as George Horany, is a picturesque water resource nestled in Creek County, Oklahoma. Managed by the local government, this reservoir was completed in 1933 and serves primarily for recreational purposes. With a dam height of 31 feet and a surface area of 33 acres, this earth dam structures the TR-CATFISH CREEK, offering a serene setting for outdoor enthusiasts and nature lovers to enjoy.
Despite its tranquil appearance, Lake Massena poses a high hazard potential due to its location and structural characteristics, with a fair condition assessment as of the last inspection in December 2021. Maintained by the Oklahoma Water Resources Board, the dam features a controlled spillway and a valve outlet gate to manage water levels and ensure safety. The reservoir holds a maximum storage capacity of 1,130 acre-feet and a normal storage level of 865 acre-feet, making it an essential resource for the local community and surrounding areas.
Situated in the Tulsa District, Lake Massena provides a vital source of recreation and water supply for residents. With its historical significance dating back to the Works Progress Administration era, this reservoir continues to be a valuable asset for water resource and climate enthusiasts interested in the management and preservation of inland water bodies. As climate change impacts water availability and quality, the regulation and maintenance of Lake Massena highlight the importance of sustainable water resource management in the face of evolving environmental challenges.

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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lake Massena
Where does the data for Lake Massena 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 High 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.
