2 Lower and middle shutters have been installed for cold water pool conservation; upper shutters will go in once storage is high enough for the shutters to be safely installed Temperature Management: Isothermal conditions in Folsom Lake CORRECTION: Under the 90% runoff exceedance outlook, MRR for February should read 1750, not % runoff exceedance outlook slightly ahead of of the 50% forecast due to last storm event Current 50% and 90% forecasts are currently only benchmarks on potential operations Discussion Presentation Jose Setka from EBMUD Mokelumne Fish Hatchery o Jose to send powerpoint presentation The next meeting is scheduled to take place on Thursday, February 21st, 2019 at Central Valley Operations Office, 3310 El Camino Ave., Sacramento, CA 95821, in Room 302, at 1:30pm.

4 American River Summary Conditions January (On-going): Precipitation season has officially begun. We have just had the largest storm so far of the season. While we are still below average for the water year, January precipitation has gone far to bring us back to a much better position than we were in in December Storage/Release Management Conditions Releases to maintain spawning/incubation habitat for fall and winter. Beginning water storage for next years operational needs. Will be operating to new Army Corps flood control diagram on an interim basis until new Water Control Manual is signed, per letter from USACE. MRR for January is 1,750 cfs. Anticipate February MRR being 1,750 cfs also. Temperature Management: Temperature management is concluded for the season.

5 CDFW FISHERIES UPDATE FOR THE AMERICAN RIVER GROUP January 17, 2019 Presented by Jeanine Phillips (916) SALMON ESCAPEMENT SURVEY Duration: 13 weeks, ended on January 9 > 12,000 carcasses processed o 66% of carcasses encountered on and above the weir o Stray rate of hatchery fish is ~70%, the majority from the Mokelumne River Hatchery Other hatcheries/rivers: Merced, Feather, Coleman, San Joaquin R. ROTARY SCREW TRAPS (update provided by Kassie Hickey, PSMFC via ) Fin clips of fish designated as winter-run with LAD criteria will be genetically analyzed at the end of the sampling season to verify winter-run designation NIMBUS HATCHERY Salmon spawning ended on December 14 th, the week the weir was removed o 8 million egg-take goal was reached Steelhead spawning began on December 17 th o The run appears to be good Spawning occurs once per week through approx. end of February, or when spawnable pairs stop arriving at the hatchery ~1/2 of the egg-take goal has been achieved

6 Lower American River RST Catch Summary Pacific States Marine Fisheries Commission Sampling start date: 1/10/2019 Thus far we have captured a total of 14 length-at-date (LAD) fall-run and 4 LAD winter-run Chinook salmon.

8 SMUD Upper American River Project Update Conditions 15 January 2019: January precipitation at Fresh Pond through 1/15/2019 7:00:00 AM is 4.06 in., which is 43% of the January average of Precip for the water year to date is which is 71% of average to date (23.93 ) and 30% of the entire water year average of Reservoir storage for Loon Lake, Union Valley and Ice House Reservoirs is currently at 53% capacity (199,628 acre feet), with Loon Lake at 36,580 af, Ice House at 14,593 af, and Union Valley at 148,454 af. Last year today, storage was at 63% (239,209 acre feet). Total capacity of the three reservoirs is 379,174 acre feet. The SMUD reservoirs are at 88% of historical average at this date (15 January historical average 227,112 acre feet / 60% capacity). The reservoirs have not decreased in volume since last week. During the month of December 2018 SMUD released from the Upper American River Project reservoirs approximately 38,000 acre feet of water, with average flows at 617 cfs below Chili Bar. So far in January (Jan 1-14), we have released 22,382 AF, at flows of ~806 cfs below Chili Bar on average. Runoff into the storage reservoir basins is 74% of median to date through Jan 14. The snowpack is 83% of average at selected snow sensors.
