Diamond Lake

Description

Diamond lake is located 30 miles northwest of Laramie off the Cooper Cove exit (279) on I-80 between I-80 and Medicine Bow. Diamond had been a great fishery for many years but then ran dry for a decade+. Around 2016 the Game and fish was able to secure water for the lake again and it has been getting better and better. If you are googleing directions use “Bosler Reservoir, Wyoming” and you’ll end up in the right place.
