Commercial fishermen are back on Lake Sinissippi. Since the end of July, Steve and the crew have fished many areas of the lake and loaded fish from both OX-BO and Neider Park. Be aware of nets in the water.
LSA supports carp removal through your donations. Read an interesting article from the Watertown Daily News about commercial fishing on Lake Sinissippi.

Join LSA for the Rock River Sweep at Lions Park. The event has been postponed. A new date will be posted soon. Volunteer a morning to help clean up the river.
