Brocks Mill Dam dam
Brocks Mill Dam
Brocks Mill Dam, located in Albemarle, Virginia, is a privately owned earth dam that serves the primary purpose of flood risk reduction. Standing at a height of 30 feet and spanning a length of 180 feet, the dam has a storage capacity of 52 acre-feet and covers a surface area of 1.4 acres. Despite its important role in mitigating flood risks, the dam's hazard potential is currently labeled as undetermined, with a condition assessment that is not rated.
Managed by the Department of Conservation and Recreation in Virginia, Brocks Mill Dam is subject to state regulations, permitting, inspection, and enforcement. While the dam's emergency action plan status and risk assessment are not specified, the structure has not been modified in recent years. The dam does not have outlet gates or associated locks, and its spillway type and width are not provided in the available data. With its critical function in flood risk reduction, the condition and safety of Brocks Mill Dam are crucial considerations for water resource and climate enthusiasts in the region.
Although the specific construction date and last inspection details are missing, the presence of regulatory oversight and state jurisdiction suggest a commitment to maintaining the integrity of Brocks Mill Dam. With its strategic location in a flood-prone area and its importance in protecting surrounding communities from potential water hazards, the need for ongoing monitoring and assessment of the dam's structural integrity remains a priority. As water resource and climate enthusiasts continue to advocate for sustainable water management practices, the significance of structures like Brocks Mill Dam in safeguarding against flooding events cannot be understated.
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.

About Brocks Mill Dam
Where does the data for Brocks Mill 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.
