Guilford Reservoir Storage Tanks dam
Guilford Reservoir Storage Tanks
The Guilford Reservoir Storage Tanks in Baltimore City, Maryland, were completed in 1893 and serve as a vital water supply source for the area. Managed by the local government, these tanks have a primary purpose of water supply and are regulated by the Maryland Dam Safety agency. With a normal storage capacity of 104 acre-feet and a maximum storage capacity of 134 acre-feet, the reservoirs play a crucial role in ensuring a stable water supply for the surrounding community.
Constructed with a core type of Multi-Arch and built on a foundation of rock and soil, the Guilford Reservoir Storage Tanks stand at a height of 35 feet with a length of 2375 feet. Despite being classified as a high hazard potential structure, the condition assessment has deemed them to be satisfactory. Regular inspections and maintenance ensure the safety and reliability of these storage tanks, which have no spillway and utilize needle outlet gates for water release. As climate change impacts water resources, the Guilford Reservoir Storage Tanks remain a critical infrastructure for water management in the region.
Located near the Offstream-Stoney Run water source, the Guilford Reservoir Storage Tanks play a crucial role in the water supply system of Baltimore City. With a high risk assessment rating of 2, it is essential for local authorities to continue monitoring and implementing risk management measures to ensure the resilience of this key infrastructure. As water resource and climate enthusiasts, understanding the importance of such structures in maintaining water security and adapting to changing environmental conditions is paramount for sustainable water management practices.

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 Guilford Reservoir Storage Tanks
Where does the data for Guilford Reservoir Storage Tanks 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.
