Landels-Hill Big Creek Reserve

24 Aug, 05 AM - 26 Aug, 05 AM

The primary research sites for this study of the Big Creek population of steelhead (Oncorhynchus mykiss) are 1-the first pool immediately upstream from the mouth of Big Creek, 2-the Big Creek pool immediately upstream from the confluence with Devil's Creek, 3-the "carriage bridge" pool downstream from the hot springs and 4-the pool at the bridge crossing Devil's Creek at Redwood Camp. Additional pools within the Devil's Creek and Big Creek drainages will also be studied on a secondary basis. Since 1999 I have been studying pigment variation of the steelhead populations here. I have collected census data for 2 morphological units: a 'normally pigmented form and a 'cream' or lightly pigmented form. Using wetsuit, mask, snorkel, underwater paper and camera, I make visual counts of the number and age distribution of normal and light pigmented steelhead in each pool. During this process the fish are not physically touched and care is taken to move slowly in each pool studied so as not to stress the fish. I use Redwood Camp as a base for this study.
