Pemberton Lake Dam-Sec 22 Dam
Pemberton Lake Dam-Sec 22
Pemberton Lake Dam-Sec 22, located in Cape Girardeau, Missouri, was completed in 1971 with a primary purpose of flood risk reduction. This private dam stands at a height of 30 feet and has a storage capacity of 80 acre-feet, with a normal storage level of 50 acre-feet. The dam is classified as an earth dam with a buttress core type, designed to control debris and reduce flood risks in the area.
The dam's hazard potential is rated as high, although its condition assessment is listed as "Not Rated". Despite not being regulated or inspected by the state, Pemberton Lake Dam-Sec 22 plays a crucial role in managing water resources in the region. It serves as a vital structure for protecting downstream areas and controlling the flow of the TR-Headwater Diversion Channel, highlighting its importance for both flood control and water management in the area.
While some details such as inspection frequency and emergency preparedness measures are not specified for Pemberton Lake Dam-Sec 22, its significance in mitigating flood risks and managing water resources cannot be understated. As a key element in the region's water infrastructure, this dam stands as a testament to the ongoing efforts to safeguard communities and the environment from the impacts of extreme weather events and changing climate patterns.

About Pemberton Lake Dam-Sec 22
Where does the data for Pemberton Lake Dam-Sec 22 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 High 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 below 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.
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.
