There are too many short or even single sentence paragraphs.
The majority have been fixed. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
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 ..."
Better now? --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
You could mention which side the tributaries flow in from.
What is the significance of the level of aluminium in the water?
High enough levels can cause fish kills. I've explained this. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
The paragraph starting "In 1799" contains a large number of short sentences, some of which could be joined together for better flow of prose.
Wow, my old prose is really choppy. I've merged several of the sentences. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
"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.
It would be helpful to explain what the Shannon Diversity Index and the Hilsenhoff Biotic Index are, and the significance of the figures.
I've given a rough explanation of both. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
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.
The length such a basic fact that I think it's fine in the lead and doesn't need to be repeated. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
You could explain what "riparian buffering" means.
That's already done by means of a wikilink. --Jakob (talk) 14:31, 5 March 2015 (UTC)[reply]
