Photograph by Leo Shapovalov "Spawning was also going on at the same time in Middle Creek at the State Highway 29 crossing (on the Upper Lake-Lakeport Highway). At the temperatures in degrees Fahrenheit in Middle Creek at the above bridge were air degrees, water degrees. The weather was clear. The water was slightly murky. The flow of the stream was esti- mated to be 75 second-feet or more. The average width was about 35 feet and the average depth about 10 inches. "Observations were continued only until , at which time spawning was still going on at the above bridge over Middle Creek. Tem- peratures had then risen to air 73 degrees, water degrees. "In spawning, the males kept close to and slightly behind the females, with their snouts near the vents of the females. Often four and five or more males attended one female, crowding over and next to one another. However, they were not observed fighting. "The deposited eggs were not covered by the fish. On the day of observation the stream flow was receding, and as a result many thousands of eggs were exposed on gravel bars. Under such conditions, mortality among newly laid eggs must be ; The run of fish studied by the writer entered Scotts Creek on April 17, 1947, and remained in the stream until April 26th. Roily waters at the time of the run prevented direct observation of the spawning fish. Most of the observations were made at a riffle just below the mouth of Middle Creek.
