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.
