Stopped off on the Arnold for a quick fish on the way home from work Thurs night, fishing with a spinner as the river was high. Hooked 3, kept one typical Arnold brown of a tad under 2 pounds. Stomach was absolutely chocka with toe biters (dobsonfly nymph). Have occasionally come across fish that have been feeding on these but never to this extent. Very interesting. Hopefully a sign the river is in good shape anyway.
