Griffith Lake Dam dam
Griffith Lake Dam
Griffith Lake Dam, located in Kent, Delaware, serves as a critical structure for fish and wildlife conservation and recreational purposes. Managed by the state regulatory agency DNREC, this Gravity-type dam stands at a height of 12.82 feet and spans a length of 858 feet. With a storage capacity of 409 acre-feet, the dam plays a key role in regulating water flow in the Mispillion River, benefiting the local ecosystem and providing a serene setting for outdoor activities.
Despite its fair condition assessment, the dam's Hazard Potential is classified as high, indicating the need for ongoing monitoring and maintenance. The risk assessment ranks it as Very High (1), underscoring the importance of emergency preparedness and risk management measures. With a controlled spillway and outlet gates for water release, Griffith Lake Dam exemplifies the balance between human needs and environmental protection, highlighting the complexities of managing water resources in the face of climate variability and increasing water demands.
As climate change continues to impact water resources, Griffith Lake Dam stands as a testament to the intricate interplay between infrastructure development, environmental stewardship, and public safety. By recognizing the dam's dual role in supporting wildlife habitats and recreational activities, water resource and climate enthusiasts can appreciate the challenges and opportunities associated with managing and maintaining such vital structures in a changing world.

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 Griffith Lake Dam
Where does the data for Griffith Lake 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 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 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.
