Shoemaker River # 4c dam
Shoemaker River # 4c
Shoemaker River # 4c, also known as Slate Lick Dam, is a vital piece of infrastructure located in Rockingham, Virginia. This local government-owned structure plays a crucial role in flood risk reduction along Slate Lick Creek, with a dam height of 86 feet and a storage capacity of 2159 acre-feet. The dam, primarily constructed of earth material, serves as a key defense against potential hazards, as indicated by its high hazard potential rating.
Managed by the Department of Conservation and Recreation in Virginia, Shoemaker River # 4c has undergone regular inspections to ensure its structural integrity and functionality. The dam's condition assessment in March 2020 deemed it satisfactory, highlighting its continued effectiveness in mitigating flood risks in the region. With a drainage area of 6.07 square miles and a maximum discharge capacity of 25202 cubic feet per second, this dam stands as a crucial safeguard for the surrounding community.
As climate change continues to impact water resources and increase the frequency of extreme weather events, structures like Shoemaker River # 4c play a vital role in protecting communities from potential flooding and related hazards. With its strategic location and high hazard potential designation, this dam serves as a key component of the region's resilience against the growing threats posed by a changing climate.

About Shoemaker River # 4c
Where does the data for Shoemaker River # 4c 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.

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.
