Platte River Site 8-B dam
Platte River Site 8-B
Platte River Site 8-B, also known as Platte River Trib Wtrsd Dam 8-B, is a local government-owned structure located in PARNELL, Missouri, along the TR-PLATTE RIVER. Built in 1963 by the USDA NRCS, this earth dam stands at a height of 36 feet and stretches 500 feet in length, serving primarily for flood risk reduction. With a storage capacity of 76 acre-feet and a drainage area of 204 square miles, the dam has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in 2007.
Despite its relatively modest size, Platte River Site 8-B plays a crucial role in reducing flood risks and providing recreational opportunities in the Worth County area. The dam, regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, has a maximum discharge capacity of 792 cfs and a spillway width of 7 feet. While the structure has not been modified in recent years, it undergoes inspections every five years to ensure its continued safety and functionality. Additionally, the presence of associated locks or outlet gates at the site is currently non-existent, further emphasizing its simplicity and effectiveness in flood control.
Overall, Platte River Site 8-B stands as a reliable and essential component of the local water resource management system, contributing to the overall resilience of the region against potential flooding events. With its low hazard potential, satisfactory condition, and consistent regulatory oversight, this earth dam serves as a testament to the successful collaboration between local government agencies and the USDA NRCS in safeguarding communities and enhancing the quality of life for residents in Worth County, Missouri.

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 Platte River Site 8-B
Where does the data for Platte River Site 8-B 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.
