Tat Momolikot dam
Tat Momolikot
Tat Momolikot, also known as Lake St Clair, is a federal-owned reservoir located in Stanfield, Arizona. Constructed in 1974 by the Bureau of Indian Affairs, this Earth type dam serves primarily for irrigation purposes along the Santa Rosa Wash. With a structural height of 76 feet and a dam length of 12,500 feet, the reservoir has a storage capacity of 375,000 acre-feet, making it a crucial water resource in the region.
Despite its importance in supporting agricultural activities, Tat Momolikot poses a high hazard potential and is categorized as a very high-risk structure. Emergency protocols and risk management measures are in place, although the condition assessment is currently not available. The reservoir is under the jurisdiction of the Bureau of Indian Affairs, with regular inspections scheduled every 5 years to ensure the safety and stability of the dam.
Water resource and climate enthusiasts will find Tat Momolikot an intriguing case study of water management in arid regions. Situated in Pinal County, the reservoir plays a vital role in sustaining local agriculture and serves as a critical asset for the community. With ongoing concerns about its hazard potential and high-risk classification, there is a need for continued monitoring and assessment to safeguard this essential water source for future generations.

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 Tat Momolikot
Where does the data for Tat Momolikot 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.
