At one time when the canal was built, it was lined for miles with industry. Now as far as I can tell, there is just Fiddlers Ferry Power Station.There are plenty of boats, all for pleasure these days. There is the Yacht Haven, where they are moored and repaired. Further up by Spike Island they are all moored ready to go to sea when the tide is in.
With all the mud flats when the tide is out, its a real haven for the birds. Although all I have seen are the usual, swans, ducks, canada geese, coots and moorhens.
