Prospect Lake Liner (52-Acre Liner) Colorado Springs, Colorado
Prospect Lake is located in Memorial Park in south-central Colorado Springs, Colorado. The high profile, 52-acre recreational lake has continually experienced seepage losses throughout its' 100-year history.
K+A was the principal designer responsible for the liner system and teamed with the civil engineering firm Associated Design Professionals (ADP) of Colorado Springs to complete the project.
Explored alternative liners for reducing seepage losses.
The lake is impounded by two jurisdictional dams; proposed modifications to the dams and reservoir required the approval of the State Engineer’s Office (SEO).
The greatest challenge was stabilizing the 2- to 4-foot thick highly plastic clay in the middle of the lake to support the liner and the equipment used to install it.
Approximately 224 tons of liner material, 8 miles of field seams, and 72 tons of geotextile separator fabric were placed.
