Tommy L. Mccraw Dam dam
Tommy L. Mccraw Dam
Tommy L. Mccraw Dam, located in Bedford, Virginia, is a privately owned structure regulated by the Department of Conservation and Recreation. This earth dam stands at a height of 29 feet and has a storage capacity of 56.38 acre-feet, with a normal storage level of 26.1 acre-feet. The dam's primary purpose and specific design features are not specified, but its hazard potential is labeled as undetermined and its condition assessment is listed as "Not Rated".
Despite limited information on its construction year and specific purposes, Tommy L. Mccraw Dam serves as an essential component of water resource management in the region. The dam's proximity to the Norfolk District and Congressional District 05 of Virginia highlights its importance in regulating water flow and storage in the area. While the dam's risk assessment and emergency preparedness details are currently unspecified, its presence underscores the critical role of infrastructure in mitigating flood risks and ensuring sustainable water supply in the face of changing climate patterns.
Enthusiasts of water resources and climate resilience will find Tommy L. Mccraw Dam an intriguing subject for further exploration, as its operational and regulatory aspects provide valuable insights into the management of water infrastructure in Virginia. The dam's location, storage capacity, and regulatory framework offer a glimpse into the complexities of balancing water resource needs with environmental considerations, making it a focal point for discussions on sustainable water management practices and climate adaptation strategies in the region.

About Tommy L. Mccraw Dam
Where does the data for Tommy L. Mccraw 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 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.

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.
