Mariano dam
Mariano
Mariano, also known as Boedecker Lake, is a private water resource located in Loveland, Colorado, nestled amidst the scenic Larimer County. This reservoir, primarily used for irrigation, also serves as a Fish and Wildlife Pond and a recreational spot. It was completed in 1889 and stands as a testament to early water management practices in the region. Mariano boasts a dam height of 30 feet and a storage capacity of 7680 acre-feet, with a normal storage level of 5550 acre-feet.
Managed by the Colorado Department of Water Resources, Mariano is subject to frequent inspections and regulatory oversight to ensure its structural integrity and operational efficiency. The dam, constructed with earth materials, has a high hazard potential but currently maintains a satisfactory condition assessment. The reservoir's spillway, a vital safety feature, is uncontrolled with a width of 40 feet. Despite its age, Mariano continues to play a crucial role in water supply and management in the area, demonstrating the enduring importance of historic water infrastructure in the face of climate challenges.
With a maximum discharge capacity of 1640 cubic feet per second, Mariano remains a key player in the region's water ecosystem, sustaining diverse wildlife and supporting agricultural activities. As climate change poses new challenges to water resources, the management and maintenance of structures like Mariano are essential to ensure sustainable water supply and mitigate risks of dam failures. Through ongoing risk assessments and management measures, Mariano stands as a resilient example of historic water infrastructure adapting to the evolving climate landscape, symbolizing the intersection of tradition and innovation in water resource management.
Dam data reference
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 Mariano
Where does the data for Mariano 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.
