New Zealand Mud Snail
As of early 2014, there are no known locations of New Zealand mud snails in the Upper Sacramento or McCloud Rivers. But this invasive snail is now known to occur at many locations used by fishermen in N. California. Human recreational activities are clearly an important factor in the spread of this species.

New Zealand Mud Snail infestations in California and the Western U.S. are clearly associated with recreational access points.
