a. Bathing is not advised downstream of the swing bridge at any time:
The water is continually contaminated by faecal coliform bacteria from the treated effluent outfall and frequently contaminated by storm overflow discharge. We recommend signage to that effect.
b. Bathing is not advised at the Burley Weir:
Coliform bacteria are likely always to be in relatively high concentration predominantly from inputs from Ben Rhydding.
c. Upstream of the swing bridge:
Whilst we as yet do not know all the conditions under which it is safe to bathe at the beaches, we are fairly confident that in dry weather, low flow conditions, risk from coliform bacteria and associated viruses and bacteria is low.
d. Upstream of the swing bridge and Old Bridge (tennis club/ Ilkley beach): :We are confident in our conclusion that in wet weather and when river levels are high, the risk is high .
e. Upstream of Addingham Weir:
Risk from coliform bacteria is low in all conditions. Downstream is NOT safe in rain see data.
Please note; the responsibility for the water quality lies with the Environment Agency (EA) / Yorkshire Water (YW) and our findings are entirely advisory. The public swims, paddles and plays in the river at their own risk. If you get ill then you should take it up by contacting the EA 0800 807060.
