In the summer of 2003, there was a lengthy drought and water levels remained very low through September.
Heavy rain began in early October, resulting in very high water in the creeks. There was some bank and trail wash-out on Mosquito Creek at the Griffin Channel confluence, and leaves and gravel began to block the Fell Channel intake due to stream channel changes.
Fell Channel remained free flowing, thanks to volunteers who cleared the intake daily.
Dry weather returned for the last week or so of October through the first week of November.
Chum were first seen spawning in Mosquito Creek on October 21 - one pair.

Thain Creek
Fish baffles and a ladder were installed at the Queens culvert in the summer of 2003, increasing the amount of habitat accessible to salmon.

November 5 was the first day the entire length of Thain Creek was checked, including the newly opened section from Queens to Windsor.
Passage was improved in a few areas by removing branches and leaf debris.
Some areas showed evidence of the very high water flows in early October, but all in all, things looked pretty good.
The water level was moderate-low throughout, but fish passable. A few juvenile trout or coho and one adult coho were seen.
On November 22 water levels were good.
One newly fallen small tree had blocked one side of the creek, and so we opened up that side.
Several juvenile fish and one adult coho were seen.
There may have been one or two redds. (Redds are easily identified when freshly made because the gravel is consistent and the mound is high relative to the stream bed. However, as water flows over, the redds wear down and blend in.)
Although there is now more stream accessible to salmon, there is still very little instream cover for spawners. In fact there is probably less now than there was a few years ago, due to alterations to man-made structures which had previously provided shelter.
