Grundy Canyon, Birch of a Tributary Traditional Cache

Cache is located on a very small tributary that feeds Rock Creek Trout Stream. There are many tributaries and springs above this cache making rock creek have a much better flow and I did see fish in the waters here where there is a constant flow of water. I believe current regulations for this stream is 5 trout over 7 inches but as is trout and walleye fishing in Wisconsin that always seems to change.
