I returned to Dyke Creek last Saturday with my wife so I could finish sampling in one day. We had to wake up early and we did not return home until almost midnight, but we did manage to finish the entire site. Unfortunately, we did not capture any transformers, but since Cait was with me there are pictures of me. We stopped taking pictures relatively soon after arriving as we were trying to get through samples as quickly as possible so we would finish before the sun went down.
This picture was taken just to the right of the first pool and looking downriver. The stream actually braids into two separate channels just above this point, so this is about half of the stream.
Route 417 as it passes over the site. We set up our first sample processing station just under neath. Cait moved it slightly so she could sit in the sun.
Working up an animal with the syringes used to inject the color in the foreground.
Brought a chair this time so I (or Cait) did not have to sit on the cold rocks. Temperatures started off in the 50's and rose into the high 60's low 70's by the end of the day. Water temps held steady around 58
°F.
A nice picture, taken by Cait, from the shore.
Setting up the blocking net before starting to shock to prevent lampreys from escaping while I worked.
Pictures of me sampling further upriver. The pool here had quite a bit of algae growth so my ability to catch the lampreys here (where Brooker lives) was low. That is not a problem for the models I use, but means that the total number of animals we needed to work up on this sampling occasion was not as high as in the past.
I am trying to go out again this weekend. If I succeed I will update the blog again. Until next time, happy lamprey hunting.
