Comment:  Reduce flows for Memorial Day weekend

American River Group Temperature Plan & Handouts

Posted on Tuesday, May 23rd, 2017

 

 

Reclamation aims to fill the reservoir by late June, with a possible lowering to 5,000 – 6,000 cfs for Memorial Day weekend for boater & rafter safety.

Initial iCPMM modeling suggests that ATSP schedule 23 (64 degrees with one-degree buffer at Watt Avenue) can be achieved. This is based on all upper shutters being lowered. Currently only the lower and middle shutters are lowered units 1 and 2 (unit 3 is our for maintenance). The upper shutters are not in place because of a large amount of debris. This will impact the cold water pool if not resolved. Divers may be able to clear the debris, but that is not known.

Mulch Mayhem!

Posted on Wednesday, May 3rd, 2017

Get ready for MULCH MAYHEM!

Free water-conserving mulch will be available to local residents during Mulch Mayhem events throughout the Sacramento region on Saturdays May 6 and 20. These free events are designed to help local residents get their landscapes and yards ready for the hot days of summer. Mulch slows evaporation, moderates soil temperature and even controls weeds. As it breaks down, mulch also adds helpful nutrients to the soil.
“Mulch might be one of the most under-appreciated water conservation tools at our disposal,” said Amy Talbot, Regional Water Authority Water Efficiency Program Manager. “Mulch is like icing on a cake because it keeps the soil moist the way icing keeps a cake moist.” Water managers estimate that residents can save 30 gallons of water for every 1,000 square feet just by adding two to three inches of organic mulch (e.g., leaves and wood chips) around trees and plants.
Sponsored by the Regional Water Authority and local water providers, Mulch Mayhem will take place at the following locations, days and times (until supplies last):

Saturday, May 6

Antelope Gardens | 9 am – 12 pm
7800 Antelope North Rd. in Antelope
Hosted by Sacramento Suburban Water District

Carmichael Water District | 9 am – 12 pm
7837 Fair Oaks Blvd. in Carmichael
Hosted by Carmichael Water District

Sierra College, Overflow Lot | 8 am – 12 pm
Corner of Rocklin Rd. and El Don Dr. (opposite the campus)
Hosted by Placer County Water Agency
and the City of Lincoln

Saturday, May 20

Placer County Fair Grounds, Lot B | 9 am – 12 pm

Hosted by the City of Sacramento

San Juan Water District | 9 am – 12 pm
9935 Auburn Folsom Rd. in Granite Bay
Hosted by the San Juan Water District

Free mulch is limited to one yard per customer (enough to fill a pickup truck), must be for personal use only (not for resale or commercial use) and will be offered on a first come, first-served basis until supplies are gone. Customers are encouraged to bring their own shovels, containers, tarps or other items to cover the mulch and must provide their own way to haul it away.

American River Group Handouts

Posted on Monday, April 24th, 2017

Reclamation released flow projections for April through September for the lower American River at the monthly ARG meeting 4/20/17.  Peggy noted that the lower two shutters are in place for the two working penstocks. The third penstock is out for maintenance and is expected to be back online soon with the lower two shutters. They are having difficulties with the upper shutter because of debris.

Five water monitoring stations were damaged during the high water.  They are expected to be repaired/relocated by the end of April.
