From The Mountain Mail (Joe Stone):
Addressing issues with a leaky Boss Lake dam in southwestern Chaffee County could cost as much as $2 million.
Terry Scanga, general manager of the Upper Arkansas Water Conservancy District, estimated the cost at $1.5-2 million during the Thursday district board of directors meeting.
Scanga said an environmental impact statement would need to be prepared in order to construct a road across national forest land to get equipment into the site.
Confronted with the cost of dam repairs and the cost of an environmental impact statement, Scanga would not recommend moving forward with repair work, saying the lake has “limited utility for the district’s uses.”
During the Upper Ark district’s March 2014 meeting, district officials mentioned the possibility that the dam could be breached.
Scanga said he was hopeful the state would take over the reservoir and fund the necessary repairs so Boss Lake could be used to help re-establish endangered greenback cutthroat trout, the Colorado state fish.
The Upper Ark district stores water in Boss Lake and manages the reservoir pursuant to a 1982 agreement with Chaffee County.
When the state built Boss Lake, it encompassed the Donnell 1 and 2 reservoirs, and the Donnell water rights include a storage right in what is now Boss Lake.
Salco Associates, essentially Wanda and Jim Treat and family, own the Donnell water rights, allowing the Treats to store water in Boss Lake.
In spite of efforts to engage Salco regarding dam repairs, Scanga said the district had received “no response” since the family attended the March 2014 district board meeting to protest maintenance charges billed by the district.
The board meeting also included:
