Pittsfield Sediment Trap Dam dam
Pittsfield Sediment Trap Dam
The Pittsfield Sediment Trap Dam, also known as Lake Pittsfield Rock Dam, is a local government-owned structure designed by the USDA NRCS in Illinois. Constructed in 1997 on Blue Creek in Pike County, this Earth-type dam stands at 11 feet high and spans 548 feet in length. Its primary purpose is debris control, with a storage capacity of 254 acre-feet. While the dam's hazard potential is classified as low, it is regulated, permitted, inspected, and enforced by the Illinois Department of Natural Resources (IDNR).
Situated within the St. Louis District of the US Army Corps of Engineers, the Pittsfield Sediment Trap Dam features an uncontrolled spillway with a width of 1100 feet. Despite its moderate risk rating, the dam's condition assessment is not available, and there is no Emergency Action Plan (EAP) prepared as of the latest data update in May 2021. With a drainage area of 7.9 square miles, the dam serves as a vital structure for managing debris and sediment in the region. Its location at coordinates 39.65013° N, -90.75865° W contributes to water resource and climate management efforts in the area.
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 Pittsfield Sediment Trap Dam
Where does the data for Pittsfield Sediment Trap 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.
