This information contains historical data that may be very old, but it does give a pretty complete picture of what has gone on in the basin over the years. Not all established. Many records based on one-time occurrences. Stockings are listed even if they failed.  Extirpated populations are also in the database.  Introductions have occurred due to gamefish stocking, bait bucket, aquariums, pet releases, ballast water (zms, mitten crab) and incidently with plants.
