Some of the prose is a bit "clunky". For example these two sentences could be combined, - "Shortly afterwards, it exits Sugarloaf Township.[3] Upon leaving Sugarloaf Township ..."
"The bridge was moved to South Branch Roaring Creek when it was sold to H. H. Knoebel in 1936." - Was the bridge sold or the land sold?
The bridge was sold. Should be evident to the reader since the previous sentence is about the bridge being moved to another location. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
"Approximately 60% of the taxa are Ephemeroptera, 10% each are Plecoptera, and approximately 5% are Trichoptera." - You might like to add the common names for these taxa.
The lead is supposed to be a summary of the article and only contain information mentioned elsewhere. In the lead you mention the length of the creek but do not mention this in the body of the text.
