thumb|Trumpeter Swans on Christmas Lake before ice-in in 2006.Christmas Lake is home to a number of native and introduced species of fish, the most prevalent of which are largemouth bass, bluegill and pumpkinseed sunfish, crappie, northern pike, carp, and rainbow trout. However, due to the small size of the lake, the fish (with the exception of carp) do not generally grow to large sizes. Some fish consumption guideline restrictions have been placed on the lake's bluegill, carp, northern pike, and white sucker due to mercury contamination.
