This is NOT B-IBI

At Dosewallips we found a Dragonfly for a score of 2, potentially poor water quality.

At Trident cove we found a water penny to get a score of 4, potentally poor water quality.

At Duckabush we found stoneflies, mayflies, caddisflys, leaches, and dragonflies. That gives us a score of 16. For a potentially fairwater quality.

 

 

 

This is the sheet we use to get our scores for that river or stream. We used this method for Dosewallips, Trident Cove and Duckabush, but not Chimacum Creek. We used B-IBI for that.

 

What we did was if we found one of these bugs on the score sheet, we would make an X on the line next to the bug. Even if we find more than one of the same bug, we only count it once. Then we multiply the number of checks we got in that column by the score and that is the total for that column. Then we add up all the columns and that is the rive or streams score. For example, if we found a Mayfly and a Scud, in the first column we would multiple one times 4 to get 4. Then, in the next column over, we would multiply one times 3 to get 3. Then you add 4 plus 3 which is 7. So that river or stream has potentially poor water quality.
