Crystal Lake Dam dam
Crystal Lake Dam
Crystal Lake Dam, located in Excelsior Springs, Missouri, is a private-owned structure that serves as a recreational spot for water resource and climate enthusiasts. Built in 1968, this earth dam stands at a height of 54 feet and stretches 1200 feet in length. It holds a maximum storage capacity of 2846 acre-feet and covers a surface area of 100 acres, drawing water from the Fishing River.
Despite being regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, Crystal Lake Dam is classified as having a high hazard potential but is currently in satisfactory condition according to a 2007 assessment. The dam's spillway, with a width of 320 feet, is uncontrolled, and it has a moderate risk assessment rating of 3. With a drainage area of 9900 acres, the dam plays a crucial role in managing water resources in the region and provides a haven for outdoor recreational activities.
Water enthusiasts interested in exploring the intersection of water resource management and climate resilience will find Crystal Lake Dam a fascinating case study. Its strategic location, impressive design, and critical role in water storage and flood control make it a valuable asset for the community. As a privately-owned facility, the dam's maintenance and safety measures are of utmost importance to ensure its continued contribution to the region's water resource management efforts.

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 Crystal Lake Dam
Where does the data for Crystal 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.
