I paddled from the McArthur Island Boat Launch into the Thompson River and continued upriver.
When I had gone past (and above) the east end of Rabbit Island, I crossed the river and swept down the south side of the island, gaining speed for the downriver journey.
Below Rabbit Island I crossed the river again to the channel on the west end of McArthur Island and then turned into the channel.
There were lots of ducks and geese in the brackish water of the island lagoons, including quite a few goslings.
It is not possible to paddle around McArthur Island. I had to turn around at 12th Street, but out and back is 2.5 km. Back at the river, I knew the current was too swift on the shoreline of McArthur Island, so I crossed back to the north side of Rabbit Island and continued upstream until I could cross back over where the river does not move as quickly. The whole route is about 8 km with some energetic upstream paddling during freshet.
