From December 2nd 2020, Anyone from a Tier 3 Area must not travel into a Tier 1 or 2 area regarding fishing. Which evidently means that nobody should be fishing our waters in England from those areas, which the links below feature more information and guidance.
Please respect the rules, any individuals fishing our waters from Tier 3 areas will be asked to leave by any of our Baliffs or Water Keeper.
