Figure 11. Measured heating effect of Fern Ridge Lake in the Willamette River basin, based on temperature measurements upstream and downstream of the lake. The first of two available datasets was documented by Moore (1967); the second was derived from measurements during 1946-62 at the USGS stations at Noti (upstream, 14166500) and at Alvadore (downstream, 14169000) (Moore, 1964).
