Collecting Event Remarks Water temp. = 17 C. Many males in nuptial coloration, 25-50% of large fish. A trout about 7 cm was observed eating a stickleback which was about 1/3 its size. We observed it for about 2 minutes during which it held the stickleback in its mouth head in, up to about the pelvic spines. It swam about slowly repositioning it, spat it out 3 times, and the recaptured it. When stickleback was spat out, it swam away, weakly about 10 cm from the trout which easily recaptured it. Garter snake from downstream most area was a Santa Cruz garter snake. Also numerous red legged frogs. Most sticklebacks caught in downstream area. Numerous Taricha seen. A man whose family owns this land came along and told us that he expected this part of the creek to go dry at the end of the summer, although his father had never seen it go dry in 65 years. His grandfather had seen it go dry in the 1880s. He also mentioned that Cal. Fish and Game had planted trout in the 1950s. We checked the creek about 1 mile upstream and sticklebacks were absent. Also caught Oncorhynchus mykiss.
