Middle Fork Of Anderson River - No. 2 dam
Middle Fork Of Anderson River - No. 2
Middle Fork of Anderson River - No. 2, also known as Mill Lake, is a key flood risk reduction structure located in Perry, Indiana. Owned by the federal government and designed by USDA NRCS, this earth dam stands at a height of 28 feet and spans 1200 feet in length. Completed in 1969, it serves the primary purpose of flood risk reduction for the surrounding area, with a normal storage capacity of 108 acre-feet and a maximum storage capacity of 2026 acre-feet.
Situated on the TR-Little Sulpher Creek, this dam has a low hazard potential but is currently assessed to be in poor condition as of 2000. Despite its moderate risk level, the structure has not been modified in recent years and lacks updated emergency action plans and inundation maps. With a last inspection date in 2005 and a scheduled inspection frequency of 5 years, there is a need for further risk assessment and management measures to ensure the safety and effectiveness of this important water resource infrastructure.
As climate change and extreme weather events continue to impact water resources, the Middle Fork of Anderson River - No. 2 plays a crucial role in mitigating flood risks in the region. With its outdated condition assessment and lack of modern emergency preparedness measures, there is a pressing need for investment and maintenance to ensure the long-term resilience of this vital structure in the face of evolving climate challenges.
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. 2
Where does the data for Middle Fork Of Anderson River - No. 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 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.
