J E Hopgood Dam dam
J E Hopgood Dam
J E Hopgood Dam, located in Grenada, Mississippi, is a private-owned structure regulated by the Mississippi Department of Environmental Quality. This Earth dam, with a height of 18 feet and a storage capacity of 115 acre-feet, serves primarily for recreational purposes. The dam, designed as a Buttress core type, has an undetermined hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Despite lacking certain details such as the completion year and inspection frequency, the dam presents a moderate risk level, according to the data provided. With an uncontrolled spillway and no locks associated with it, the dam remains a key feature for water resource enthusiasts interested in the dynamics of water management in the Vicksburg District. The presence of the structure also underscores the importance of monitoring and managing such infrastructure for both safety and environmental reasons in the region.
For water resource and climate enthusiasts, J E Hopgood Dam offers a fascinating case study in private ownership and state regulation of water structures. Its location in Mississippi, within the Grenada area, adds to the intrigue of understanding the interplay between human-built infrastructure and natural hydrological systems. The dam's moderate risk level and recreational purpose provide valuable insights into the complexities of managing water resources and infrastructure in a changing climate scenario.

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 J E Hopgood Dam
Where does the data for J E Hopgood 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 Undetermined 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.
