In many ways, the river ecosystem has made a remarkable recovery. Trout, many invertebrates, and some plant species have done well. Ospreys have continued to increase in number and the 1999 surveys show a much improved rate of reproductive success. In contrast, species such as molluscs, salamanders, and some riparian trees will take many years to reach pre-spill populations.

The Council's Annual Reports contain updated information on recovery status. For further details of the spill event, please refer to the 1996 Annual Report.
