State Street Dam dam
State Street Dam
State Street Dam, also known as Alma Dam, is a gravity-type dam located on the Pine River in Alma, Michigan. Completed in 1938, this dam primarily serves the purpose of water supply, with a maximum storage capacity of 1500 acre-feet and a normal storage capacity of 600 acre-feet. The dam is regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
Standing at a height of 18 feet and a length of 355 feet, State Street Dam has a controlled spillway with a width of 97 feet to manage maximum discharge of 5000 cubic feet per second. Despite being assessed as having significant hazard potential, the dam's condition is deemed satisfactory as of the last inspection in May 2018. With a very high risk rating, measures for risk management and emergency preparedness are crucial for this structure, although details on emergency action plans and risk mitigation strategies are currently not specified.
Overall, State Street Dam plays a critical role in water resource management for the local community, highlighting the importance of maintaining its structural integrity and implementing effective risk management practices to ensure the safety of residents and the surrounding environment in the face of potential hazards and emergencies.

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 State Street Dam
Where does the data for State Street Dam 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.
