Lake Miami Sediment Basin - Middle Site dam
Lake Miami Sediment Basin - Middle Site
Lake Miami Sediment Basin - Middle Site is a Grade Stabilization structure located in Eddyville, Iowa, along Tr-Bluff Creek. Built in 2000 by the USDA NRCS, this Earth dam stands at 33 feet high and spans 300 feet in length, with a storage capacity of 27 acre-feet. Serving as a key control point for sediment runoff, the basin covers a surface area of 2 acres and drains a small watershed of 0.09 square miles.
Despite its low hazard potential and moderate risk assessment, Lake Miami Sediment Basin has not been rated for its condition. The uncontrolled spillway design suggests a minimal risk of overflow, with no outlet gates or locks reported. While the structure is not under state regulation or inspection, its primary purpose of Grade Stabilization remains crucial for maintaining water quality in the area. For water resource and climate enthusiasts, this site offers a fascinating case study in sediment management and erosion control within the context of agricultural landscapes in Iowa.
With its strategic location and significant impact on local water quality, Lake Miami Sediment Basin - Middle Site represents a vital piece of infrastructure in Monroe County, Iowa. As a State-owned facility, it plays a crucial role in preventing soil erosion and protecting downstream water resources. The absence of a designated Emergency Action Plan and lack of recent inspections raise questions about the long-term management and maintenance of this structure, highlighting the need for continued monitoring and oversight to ensure its continued effectiveness in sediment and erosion control efforts.

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 Lake Miami Sediment Basin - Middle Site
Where does the data for Lake Miami Sediment Basin - Middle Site 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.
