Morrison Rockwood Siltation Pond Dam dam
Morrison Rockwood Siltation Pond Dam
The Morrison Rockwood Siltation Pond Dam, located in Whiteside County, Illinois, is a state-regulated structure designed for debris control on the TRIB ROCK CREEK. Completed in 1981, this earth dam stands at a height of 29 feet and spans 410 feet in length, with a maximum storage capacity of 140 acre-feet. Despite its uncontrolled spillway and outlet gates, the dam has a low hazard potential and a moderate risk assessment rating.
Owned and operated by the state with oversight from the Illinois Department of Natural Resources, the Morrison Rockwood Siltation Pond Dam serves a crucial role in managing water resources in the region. Although specific condition assessments are not available, inspections are conducted every five years to ensure the structure's integrity and safety. With its strategic location and purposeful design, this dam contributes to the overall environmental health and sustainability of the area.
For water resource and climate enthusiasts, the Morrison Rockwood Siltation Pond Dam offers a fascinating example of engineering ingenuity and environmental stewardship. As a key component in the management of debris and water flow on TRIB ROCK CREEK, this earth dam showcases the importance of maintaining and regulating such structures for the protection of surrounding communities and ecosystems. With a focus on risk assessment and hazard mitigation, the dam represents a harmonious balance between human intervention and natural processes, highlighting the complex interplay between water resources, infrastructure, and climate resilience.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Morrison Rockwood Siltation Pond Dam
Where does the data for Morrison Rockwood Siltation Pond 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.
