Pulse Flows. Short term elevated levels of release from Project dams in 13 amounts and durations specified in Appendix A, Section 1, 14 Paragraph 3(A). 15 Ramping Rate: The rate of change in a flow release or Controlled Spill 16 from a dam expressed as an increase or decrease in discharge (in cfs) 17 over a period of time. See Appendix A, Section 1, Paragraph 6. 18 Reconstruction: Replacing or rebuilding a majority of a structure or 19 recreation site, which has reached the end of its useful life or has 20 been destroyed or damaged as a result of a natural event such as a 21 landslide, storm or wildfire. Reconstruction also includes 22 improvements aimed at expanding the capacity of an asset or 23 otherwise upgrading it to serve needs different from, or significantly 24 greater than those originally planned.

Pulse Flows. Licensee shall provide one Pulse Flow release from both Canyon 22 Dam (Seneca Reach) and Xxxxxx Forebay Dam (Xxxxxx Reach) in each of January, 23 February and March if the forecasted Water Year Type for that month, as defined in 24 Section 4, indicates that the water year is anticipated to be either Normal or Wet. No 25 Pulse Flows are required in months where the Water Year Type forecast for that 26 month indicates that the water year will be either Dry or CD. No Pulse Flows will be 27 required in March in the respective reach if two successive days of mean daily water 28 temperature greater than 10 degrees C are measured at gages NF-2 (Seneca Reach) or 29 NF-70 (Xxxxxx Reach), or if rainbow trout spawning in the Seneca or Xxxxxx Reaches 30 is observed and reported to Licensee by CDFG or FS. In both the Seneca and Xxxxxx 31 Reaches, the total volume of water released for each Pulse Flow event (including the 32 water released during the ramp up and ramp down periods) shall not exceed 1,800

In both the Seneca and Xxxxxx Reaches, the total volume of water released for each Pulse Flow event (including the water released during the ramp up and ramp down periods) shall not exceed 1,800 AF. Initially, the typical schedule will be to increase the streamflow at the Basic Ramping Rate to reach the peak streamflow, and hold the peak streamflow for 12 hours. The peak streamflow is variable by month and Water Year Type as follows: 675 cfs in January of Wet and Normal water years; 1,000 cfs in February and March of Normal water years, and 1,200 cfs in February and March of Wet water years. In the Seneca Reach during March of Normal and Wet years, streamflow will be reduced at the Basic Ramping Rate until 400 cfs is reached, held at that streamflow for 6 hours, and then reduced at the Basic Ramping Rate until the Minimum Streamflow specified in Table A-1 above is reached. The 6-hour period of constant streamflow during the ramp down shall occur between 9 AM and 3 PM of a weekend to allow recreational boating opportunities. In the Xxxxxx Reach, the peak streamflow will be reduced using the Basic Ramping Rate until the Minimum Streamflow specified in Table A-2 above is reached, but no period of constant flow during the ramp down will be required in any month.
