Seney B-1 Pool Dam dam
Seney B-1 Pool Dam
Seney B-1 Pool Dam, located in Schoolcraft, Michigan, is a federal-owned structure designed by the U.S. Department of Agriculture for the primary purpose of creating a Fish and Wildlife Pond along Gray's Creek. Completed in 1937, this Earth-type dam stands at a height of 9 feet with a hydraulic height of 8 feet, and a structural height of 10 feet. It spans a length of 12,806 feet and has a normal storage capacity of 178 acre-feet, serving a drainage area of 43.8 square miles.
Despite its low hazard potential, the dam is currently in poor condition as of the last inspection in July 2018. It has a very high risk assessment rating, indicating a need for immediate attention and potential risk management measures. The dam has undergone structural modifications in 1950 and is under state regulation by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE). With a maximum discharge capacity of 852 cubic feet per second, the dam plays a crucial role in managing water resources and supporting wildlife in the area.
Enthusiasts of water resources and climate will find the Seney B-1 Pool Dam an intriguing structure that not only serves as a habitat for fish and wildlife but also poses a significant risk due to its poor condition and high-risk assessment. Located in a picturesque setting in Schoolcraft, Michigan, along Gray's Creek, this dam is a focal point for conservation efforts and regulatory oversight. As efforts continue to maintain and manage this vital water resource, the dam's significance in the region remains paramount for both environmental sustainability and public safety.

About Seney B-1 Pool Dam
Where does the data for Seney B-1 Pool 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 Low 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 below 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.

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.
