About this dam

Mill Creek Water Reclamation District Dam

The Mill Creek Water Reclamation District Dam, located in Geneva, Kane County, Illinois, stands as a crucial structure designed by SHEAFFER & ROLAND and completed in 1995. This Earth-type dam, with a height of 9 feet and a length of 5250 feet, serves a primary purpose of "Other" and holds a maximum storage capacity of 401 acre-feet. The dam is state-regulated by the Illinois Department of Natural Resources, ensuring that it meets the necessary safety and operational standards.

With a high hazard potential and a moderate risk assessment rating, the Mill Creek Dam plays a vital role in managing water resources in the area. It is equipped with an uncontrolled spillway and has a surface area of 25.4 acres. Despite its condition assessment not being available, the dam undergoes regular inspections, with the last one conducted in October 2019. The dam's location on the Mill Creek - Offstream enhances its significance in water management and climate resilience efforts.

As a key infrastructure owned by a Public Utility, the Mill Creek Water Reclamation District Dam represents a critical component in the water management system of Kane County, Illinois. Its importance in flood control, water storage, and environmental protection highlights its role in safeguarding the local ecosystem and communities against water-related risks. Climate enthusiasts and water resource experts value the dam for its contributions to sustainable water management practices and its positive impact on the region's resilience to climate change.

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.

FAQ

About Mill Creek Water Reclamation District Dam

Where does the data for Mill Creek Water Reclamation District 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 High 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.
