Another ramp is located on the eastern side of the lake which allows fishermen to go to the deeper part of the lake or to the flooded timber just to the south of the dock.

In this sentence, the "which" clause is confusing because it at first appears to refer to "lake." [Note that it also emphasizes the location of the ramp and relegates its function to the subordinate clause.]

1 Rewrite the sentence, making "allows" the main verb and subordinating "is located."

2. Rewrite your response to (1) as a gerundive.
