Mike Conkey, from Tahosa Lodge #383, on 5/3/2019 posted on Patch-L that Western Colorado Council has merged into the Denver Area Council. He also explained that its lodge, Mic-O-Say 541, probably merged at the same time, and was referred to as a lodge chapter soon after:
"The first real big fall-out of the LDS pulling from the BSA. WCC had 2,000 Scouts and over half are LDS. With only 1,000 Scouts left scattered over half the state, the WCC was financially unable to continue as a separate Council.
The DAC has 32,000 Scouts, of which 5,000 are LDS. So we will feel the hit of the LDS pulling as well. The Council is hopeful to retain 10-20 percent initially, as some will continue their trail to Eagle. But in the long run, few LDS youth will have a go at Scouting."
From the Denver Area Council's blog:
"On May 1, 2019, the Denver Area Council (DAC) expanded the communities it serves to include 14 additional counties in western Colorado. The change will allow youth in these communities to continue their Scouting journey with additional programs, financial support, and access to dedicated volunteers and staff who help make Scouting possible.
"The Denver Area Council now serves more than 34,000 youth and the following 24 counties: Adams, Arapahoe, Broomfield, Clear Creek, Denver, Douglas, Elbert, Gilpin, Jefferson, Park, Delta, Eagle, Garfield, Gunnison, Hinsdale, Mesa, Moffat, Montrose, Ouray, Pitkin, Rio Blanco, Routt, San Miguel, and Summit.
The Denver Post provided more background to this development, that includes the loss of support from the LDS Church:
"The church-- widely known as the Mormon church-- holds conservative social stances and will end its partnership with the organization Jan. 1,  which is expected to draw away church members.
An official says the anticipated split with the church was not the sole reason for the merger, which will give western Scouts access to more programs and funding."
