Every year there is a Mid-Columbia Earth month, during this month in Tri-Cities there is an Atomic Dive Club that conducts a river clean-up. Through talking to some friends, during this dive the participants dive to the bottom of the river and pick up trash. Anything they can remove from the river that is not supposed to be in the water will be removed. This helps with keeping fish healthy and not creating a flowing sewer. When the debris is found it is hauled to shore via a line or lifted to a floating barge. If you are able to help with this effort I recommend contacting the Atomic Dive Club in Pasco, WA for more information.
