Gard Lake Dam dam
Gard Lake Dam
Located in Hannibal, Missouri, Gard Lake Dam is a private structure primarily designed for recreation purposes. Completed in 1966, this Earth-type dam stands at a height of 10 feet and has a storage capacity of 112 acre-feet. With a normal storage level of 70 acre-feet and a surface area of 21 acres, Gard Lake Dam serves as a popular spot for water enthusiasts seeking leisure activities in the area.
Managed by the Rock Island District of the US Army Corps of Engineers, Gard Lake Dam poses a low hazard potential and has not been rated for its condition assessment. While it is not regulated by the state and does not require permitting or inspections, the dam continues to be a key feature in the local landscape, offering opportunities for boating, fishing, and other recreational activities along the TR-North River. Despite its simple design and limited structural features, Gard Lake Dam remains a cherished destination for water resource and climate enthusiasts in Marion County, Missouri.
Although lacking detailed information on its spillway type, inspection frequency, and emergency preparedness measures, Gard Lake Dam stands as a testament to the enduring appeal of water resources for leisure and relaxation. As an unassuming yet essential part of the local ecosystem, this dam provides a tranquil setting for residents and visitors alike to enjoy the natural beauty of the region while also serving as a reminder of the importance of sustainable water management practices in the face of climate change challenges.

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 Gard Lake Dam
Where does the data for Gard 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 Low 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.
