From the Boulder Daily Camera (John Aguilar):

The Baseline Land and Reservoir Co., which owns the reservoir at Cherryvale and Baseline roads, is slowly draining it in order to put $400,000 worth of work into two century-old, earthen dams.

“It wasn’t that it failed,” said Brad Dallam, assistant city engineer for Lafayette. “It’s just a new modern standard.”

Lafayette counts on the Baseline Reservoir for about half of its drinking water, and the city owns the majority — 68 percent — of the shares in the lake. Others that draw from the reservoir include Boulder, Louisville and the Boulder Valley School District.
