Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
