Here is a .PDF detailing the City of Longmont Master Plan. Page 17 shows the results of th DOW view on the lake... not very good. Shallow, and too many Carp. Don't let if deter you from fishing though, in the times I have been out there I did ok on S.M. nothing big but 10-12". BTW they forgot a comma between Sunfish and Walleye, leaving tired people like me wondering what in the world a Sunfish Walleye is.
