Middle Fork Of Anderson River - No. 11 dam
Middle Fork Of Anderson River - No. 11
Middle Fork of Anderson River - No. 11 is a flood risk reduction dam located in Perry, Indiana, designed by the USDA NRCS and completed in 1992. The dam is owned by the local government and regulated by the Indiana Department of Natural Resources. It serves the primary purpose of flood risk reduction and is classified as an earth dam with a height of 31.6 feet and a storage capacity of 154 acre-feet.
This dam, situated on an unnamed tributary of the Anderson River, has a low hazard potential and is in fair condition as of the last assessment in 2015. With a drainage area of 0.48 square miles and a normal storage capacity of 7 acre-feet, it plays a crucial role in managing water flow and reducing the risk of flooding in the surrounding area. Despite its high risk assessment due to its location, the dam has not undergone significant modifications over the years and is not operated by the US Army Corps of Engineers.
Water resource and climate enthusiasts will find Middle Fork of Anderson River - No. 11 to be a vital infrastructure for flood control in the region, showcasing the collaboration between local government agencies and federal designers to address environmental challenges. Its presence highlights the importance of sustainable water management practices in safeguarding communities against potential hazards, while also serving as a reminder of the ongoing efforts required to maintain and inspect critical infrastructure to ensure public safety and environmental resilience.
Dam data reference
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 Middle Fork Of Anderson River - No. 11
Where does the data for Middle Fork Of Anderson River - No. 11 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.
