First of all, had Kathren Stevenson, our Restoration Director, not looked
into El Centro pool, we would not have known of this fish kill. Many thanks to
Kathren's alertness and the City's responsiveness. This underscores the value of
FOSC. We add immense value to the watershed.
The kill was evidently caused by a dumping of a painting solvent into the
gutter on Oakmore Ave. that drains into a side tributary at the turnaround area.
The fumes were noxious on the trail and worse at the drain. Craig Pons of the
City collected some white liquid for analysis and Kathren collected a fish for
EPA tissue analysis.
It is of interest to note that 11 trout died in the stretch of creek from the
turnaround area downstream to some point. The floaters drifted down and fell
into the El Centro Pool and sank. No trout were seen downstream by me of this
point. So that (was) a pretty healthy population in a small stretch of
restored streambank. While I was there, so was a Great Blue Heron perched in the
alders above the kill site probably looking for easy pickings. I hope a toxic
food chain doesn't develop.
The heron had easy access because of the downed trees at Benevides. The Tree
Service finished cutting up the Benevides oak branches, and took it all down
to the stumps, so the tree cannot resproat from any branches. (I'll refrain
from any further comment about this).
It occurred to me however, that the fallen oak have have been a victim of
wind throw. The previous removal of tall acacias were taken down and the next big
storm with high winds toppled the oak. The forest structure changed and may
have exposed the oak to more wind and with wet earth, it fell. We must consider
our role in its demise. And the hard-learned lesson here may be the value of
This area is across from the fish kill and looks like FOSC has work to do to
repair the areas. If we don't, then nobody will. And again that is the immense
value of FOSC and I wonder how many outside of this list really appreciate
this fact. "We all live downstream."
