Alice Lake is located entirely within William O'Brien State Park and has been managed as part of the DNR Fishing in the Neighborhood Program since 2001. Prior to that it was managed as a children's fishing pond beginning in the 1960's. The lake is impounded and shallow, maximum depth 9.0 feet, but not prone to winterkill. The water source is groundwater and the lake is occasionally inundated during high water events on the St. Croix River which introduces riverine species to the lake. Regular stocking of bluegill and crappie have occurred since the 1960's. More recently, white bass were stocked in 2002 and from 2004-2007, northern pike and yellow perch were stocked in 2002 and walleye in 2003 and 2004.
Bluegill were the most abundant species of fish sampled in the 2011 netting survey as they have been in all netting surveys conducted on Alice Lake. The average size was small though, at 4.8 inches and a maximum length of 6.8 inches. Northern pike were moderately abundant and ranged in size from 20 to 29 inches. Other panfish species such as yellow perch, green sunfish, pumpkinseed sunfish and hybrid sunfish were all sampled in low numbers and were of a small size. Species that likely emigrated to Alice from the St. Croix River during high flows were spotted sucker and golden redhorse along with one walleye. Based on the results from the 2011 netting the fishery is Alice Lake is quite average for a small lake located in this area of the state. The northern pike and walleye provide a bonus fishery and excitement factor for the youth that are targeting fish in this lake.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
