Inlet Control Structure dam
Inlet Control Structure
The Inlet Control Structure in Pinal, Arizona, serves a crucial role in flood risk reduction along the Powers Gulch stream. Completed in 2008, this private-owned structure stands at a height of 116 feet with a dam length of 735 feet. With a primary purpose of flood risk reduction, it plays a significant role in managing water flow and ensuring the safety of the surrounding area. The structure's condition assessment in 2018 deemed it satisfactory, with a hazard potential marked as significant, highlighting its importance in the region's water resource management.
Managed by the Arizona Department of Water Resources, the Inlet Control Structure is regulated, permitted, inspected, and enforced by the state. This ensures that the structure meets safety standards and continues to effectively mitigate flood risks in the area. With a storage capacity of 154 acre-feet and a drainage area of 0.74 square miles, the structure plays a vital role in managing water levels during extreme weather events. Located in a strategic position within the Powers Gulch stream, it serves as a key asset in the region's water infrastructure.
Despite its moderate risk assessment, the Inlet Control Structure remains a crucial component of the water resource management system in Pinal, Arizona. With a spillway width of 120 feet and a stone core structure, it is designed to handle significant water flow and protect the surrounding community from potential flooding. As climate change continues to impact water resources, structures like these play an essential role in safeguarding communities and mitigating the risks associated with extreme weather events.

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 Inlet Control Structure
Where does the data for Inlet Control Structure 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 Significant 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.
