Lake Mottram Upground Reservoir dam
Lake Mottram Upground Reservoir
Lake Mottram Upground Reservoir, also known as Fostoria Reservoir No. 2, is a vital water resource located in Hancock County, Ohio. Managed by the local government, this reservoir has been serving as a water supply source since it was completed in 1891. With a storage capacity of 297 acre-feet and a surface area of 15 acres, the reservoir plays a crucial role in meeting the water needs of the surrounding area.
Designed by Charles Latshaw, Lake Mottram Upground Reservoir is regulated by the Ohio Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality. The reservoir, situated along the East Branch Portage River, features an earth dam with a height of 19.6 feet and a length of 3880 feet. Despite being classified as having a high hazard potential, the reservoir is currently assessed to be in fair condition, as of the last inspection in May 2016.
Water resource and climate enthusiasts would be fascinated by the history and engineering of Lake Mottram Upground Reservoir, as well as its importance in providing water supply for the region. With its picturesque setting and crucial role in water management, this reservoir stands as a testament to the ingenuity and foresight of its designers and serves as a vital asset in sustaining the local ecosystem and community.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lake Mottram Upground Reservoir
Where does the data for Lake Mottram Upground Reservoir 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.
