Mccann Lake Dam dam
Mccann Lake Dam
Mccann Lake Dam, located in Chana, Illinois, is a privately owned structure with a primary purpose of recreation. Constructed by ENGINEERING ENTERPRISES, INC., this earth dam spans 470 feet in length and stands at a height of 13 feet. Situated on the TRIB KYTE RIVER, the dam has a normal storage capacity of 110.2 acre-feet and a maximum storage capacity of 216.9 acre-feet, making it a significant water resource in the area.
Despite its low hazard potential, Mccann Lake Dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections every five years. The dam features an uncontrolled spillway type and has a moderate risk assessment level of 3. While the condition assessment is not available, the dam has not undergone any modifications since its completion. With a surface area of 15 acres and a drainage area of 1.38 square miles, the dam plays a crucial role in water management and recreation in Ogle County, Illinois.
Water and climate enthusiasts will appreciate the ecological significance of Mccann Lake Dam, as it serves as a vital habitat for local wildlife and contributes to the overall hydrological balance of the region. As part of the Rock Island District, the dam is a key feature in the watershed, providing essential water storage and flood control capabilities. With its picturesque location and recreational opportunities, Mccann Lake Dam is not only a functional infrastructure but also a cherished natural attraction for visitors and residents alike.

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 Mccann Lake Dam
Where does the data for Mccann 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.
