Deer Run Lake Dam dam
Deer Run Lake Dam
Deer Run Lake Dam, located in Macoupin, Illinois, was completed in 1971 and is managed by a private entity. The dam, designed by USDA NRCS, stands at a height of 32 feet and has a primary purpose of recreation. With a storage capacity of 485 acre-feet, the dam serves as a popular spot for outdoor enthusiasts to enjoy activities such as fishing and boating on Deer Run Lake.
The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level. With an uncontrolled spillway and outlet gates, the dam's risk management measures are not currently specified. Although the condition assessment is not available, the dam is deemed safe for recreation and is a picturesque location for water resource and climate enthusiasts to appreciate.
Given its tranquil setting along the Tributary of Honey Creek, Deer Run Lake Dam offers a serene escape for those seeking to immerse themselves in nature while also serving as a critical water resource for the surrounding area. As a private entity-owned structure, the dam stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions.

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 Deer Run Lake Dam
Where does the data for Deer Run Lake 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.
