What a shame, cause I am actually planning on going out on Sunday, but I he HIghwood is one river I only have a moderate experience with.
Can you go elsewhere or does it have to be the HIghwood. I am more familiar with rivers adn streams further south. More north I think will still be pretty high for a bit longer, but in the south the waters are looking not too bad, high but fairly clear.
Fish are starting to get more active now too.
if you can change location I might be able to help you out
