I was lucky enough to spend the day with two scientists from California that are working on putting together a Key to Lamprey on the Olympic Peninsula. I took them to Deep Creek, East Twin, West Twin Rivers where Larry and I have had so much luck in finding macrophalmia, the transformed stage of lamprey that are about 5 years old and the size of a pencil. These macrophalmia are leaving the fresh water systems and going out to the ocean where they will be a parasite on a fish for about 2 years (no on is really sure about the time they spend out to sea). Of course we didn't have the success today finding them that we have had in the past couple of weeks. We were able to capture only a small fraction of what we have caught in the previous 2 weeks. We were going off of two main reasons for this: 1) they have moved out to sea and we were too late 2) the stream flows were up because of recent rains, or maybe it is a combination of the two. Because there isn't much known about the movement of these little guys we can't be sure about why we were so unsuccessful. The more time I spend learning about these lamprey the more questions I have.
The other awesome thing that happened today was that we got to experience a thunder and lightning storm out at Deep Creek! Thunder storms are one of the things I miss about the East Coast and this was the first storm I have witnessed this year. It was totally exciting :)
