Walker Creek Dam #2 dam
Walker Creek Dam #2
Located in Weidman, Michigan, Walker Creek Dam #2, also known as Manitonka Lake Dam, is a privately owned structure with a primary purpose of recreation. Built in 1968, this earth-type dam stands at a height of 18 feet and spans a length of 700 feet, creating a reservoir with a maximum storage capacity of 900 acre-feet and a normal storage of 301 acre-feet. The dam, situated on Walker Creek, covers a surface area of 42 acres and has a drainage area of 2.8 square miles.
Despite its recreational significance, Walker Creek Dam #2 poses a significant hazard potential with a poor condition assessment and a very high risk rating. The dam's last inspection in 2009 revealed its poor condition, highlighting the need for regular maintenance and potential upgrades to ensure public safety. With a controlled spillway type and a spillway width of 14 feet, the dam has a maximum discharge capacity of 115 cubic feet per second. The dam is regulated by the Michigan DEGLE and undergoes regular state inspections and enforcement.
Enthusiasts of water resources and climate in Isabella County, Michigan, may find Walker Creek Dam #2 an intriguing subject for further study and monitoring. As a key recreational asset in the area, the dam's structural integrity and risk management measures are critical considerations for local authorities and residents. With its historical significance dating back to the late 1960s, the dam serves as a vital component of the local water infrastructure and warrants ongoing attention to ensure its continued safe operation amidst evolving environmental conditions and regulatory standards.

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 Walker Creek Dam #2
Where does the data for Walker Creek Dam #2 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.
