Mcdonald Marsh Dam dam
Mcdonald Marsh Dam
Mcdonald Marsh Dam, located in Jackson, Indiana, stands as a testament to the conservation efforts of the Department of Interior Fish and Wildlife Service. This 8-foot high dam, completed with a length of 550 feet, serves as a vital structure for water resource management in the area. With a maximum storage capacity of 66 acre-feet, the dam plays a crucial role in flood control and water supply management.
Despite its low hazard potential, Mcdonald Marsh Dam undergoes regular inspections to ensure its fair condition and overall safety. The last inspection in September 2019 revealed satisfactory results, with an inspection frequency of every 5 years. The dam's Emergency Action Plan (EAP) status and risk assessment measures are currently not updated, highlighting the need for continual monitoring and maintenance to mitigate any potential risks associated with the structure.
Water resource and climate enthusiasts will find Mcdonald Marsh Dam to be a fascinating example of sustainable infrastructure designed to balance the needs of water supply, flood control, and environmental conservation. The dam's location in a picturesque setting in Jackson County, Indiana, further underscores its importance in the region's water management efforts. With its low hazard potential and fair condition assessment, Mcdonald Marsh Dam stands as a reliable asset in safeguarding the local ecosystem and water resources for years to come.

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 Mcdonald Marsh Dam
Where does the data for Mcdonald Marsh 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 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.
