Columbia Heights is trying to figure out what to do about the approximately 45 deer that have made themselves at home in the Twin Cities suburb. The herd resides on a 76-acre enclosed area owned by the Minneapolis Water Works. The land houses one of the state's largest water treatment plants and doesn't provide enough space or food for the dozens of deer that occupy it. Yesterday a task force recommended that the deer population be reduced by bow hunters. City Manager Walt Fehst says it's not uncommon to hear about deer popping up in the metro area. But he says the situation in Columbia Heights is unique.
