In October of 2002, an upstream blanket was placed along the reservoir
bottom just south of Horsetooth Dam.
The blanket is composed of clay and impermeable plastic layers.
The blanket covers the portion of the reservoir bed where the Forelle
limestone surfaces, helping water "escape" through the limestone, under the
In 2002, Reclamation engineers decided the upstream blanket was a more
effective treatment for the seepage underneath the dam than the originally
proposed cut-off wall.
By installing the blanket instead of a cut-off wall, Reclamation was
also able to shave time and money off the overall project.
The blanket is 800 feet long and 300 feet wide. It is covered with
clay and designed to last more than 50 years.

Once the downstream face is excavated, the contractor begins placing the filter at Horsetooth Dam.
Looking east to west across the downstream face of Horsetooth Dam, filter placement is well under way. The filter is composed of fine sand and gravel, all sorted by size and then placed in layers.
Looking down from the top of the dam shows the varying elevations and layers of the filter on the excavated face.
Looking from the the top of the dam down and slightly west, the stockpiles of materials are visible. Material used to replace the face and install the filter are sorted by size and then stored in stockpiles until they are used.
