Mount Vernon Creek
A textbook small Dane/Green County limestone spring run, tight and heavily weeded in summer with abundant watercress and a strong scud/sowbug forage base.
Weed growth concentrates fish into narrow lanes by mid-summer — read the seams.
Scuds, sowbugs, midges, ants, beetles and small BWOs are core patterns.
