Christmas Lake is 276 acres with a maximum depth of 87 feet. The water clarity is great and phosphorus is low. According to the Minnehaha Creek Watershed District, Christmas Lake has some of the best water quality in the district and the metro area. They also state that the sport fishery in Christmas Lake is excellent and its one of the few lakes in the metro area that is managed as a two story (both warm and cold water) fishery because of its depth and excellent water quality. Common aquatic plants include flat stem pondweed, curly leaf pondweed, large leaf pondweed, Eurasian watermill foil, and northern watermill foil. Rainbow trout are stocked in this lake and there is a boat ramp. Minnehaha Creek Watershed District initiated a Milfoil Weevil Study in 2012, but has been put on hold.
