Ohio environmental and wildlife officials could fill an encyclopedia with what they know about the state's major rivers and creeks. When it comes to Ohio's inland lakes, including Antrim and Alum Creek in central Ohio, the state is left holding a mostly blank piece of paper. Pushed by funding cuts and its own emphasis on stream pollution, the Ohio Environmental Protection Agency abandoned routine inland-lake testing in 1995. Though the state's monitoring program was resurrected last year, there are more questions than answers concerning the 400 public lakes in Ohio.
