Madawaska at Ottawa rivers

Mouth of Madawaska River

Arnprior, Ontario, Canada

Water is fairly fast moving along shore of town of Arnprior and running alongside town effluence pipe. Town pipe dumps contents into Ottawa approximately 300 meters from the north west land point. Town filtration centre, manicured land, boat launch (with gas pumps), town marina and walking path run along northwest side of river (above pipe line). A supervised town beach runs along the curve and shoreline on Ottawa River. Shoreline on south east side of River includes a mix of natural shoreline, docks, yacht club and housing. Some rocky areas but all well marked. Busy boating area.
