Figure 2. Timing of annual peak flow (by month) for selected rivers in Washington, Oregon, and California. If two peaks in flow occur, the indicated timing represents the timing of the first peak. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).

Figure 3. Duration of high flows (number of months when flow is equal to or exceeds 50% of peak monthly flow) for selected rivers in Washington, Oregon, and California. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).
Figure 4
Figure 4. Annual minimum monthly flow expressed as a percentage of annual maximum monthly flow for selected rivers in Washington, Oregon, and California. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).
Figure 5
Figure 5. Number of peaks of flow for selected rivers in Washington, Oregon, and California. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).
Figure 6
Figure 6. Average annual flow per area (m3s-1km-2) for selected rivers in Washington, Oregon, and California. Values were calculated as the average annual flow for each gauging station divided by the reported gauged area. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).
Figure 7
Figure 7. Annual maximum monthly stream temperatures (°C) for selected rivers in Washington, Oregon, and California. Maximum water temperatures primarily occured in July, occasionally in August. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).
Figure 8
Figure 8. Annual minimum monthly stream temperatures (°C) for selected rivers in Washington, Oregon, and California. Minimum water temperatures primarily occured in January, occasionally in February. Based on USGS streamflow data presented in Appendix Table B-1 (Hydrosphere Data Products, Inc. 1993).
