Fires & Opperations

ARG members.  As you may be aware from recent news reports, the Carr fire in northern California is currently affecting operations of all our Northern facilities.  Shasta and Keswick were both evacuated last night.  Powerline transmissions have been impacted.  CVO is currently in emergency operations mode.  While Folsom Reservoir is obviously not in the direct line of fire, as a coordinated project, there may be some temporary operational changes at Folsom, mostly relating to power generation.  It is hoped that the situation will be stabilized by next week and we can reassess project operations across all projects at that time.

Thank you for your understanding, and I will update you as new information is available.

Managing Cordova Creek: Staying ahead of Star Thistle

A native to Mediterranean Europe, the yellow star thistle (Centaurea solstitialis) made its way to California during the mid-19th century, likely via Chile through contaminated alfalfa mixes. With the lack of natural herbivores, the star thistle has the ability to create monotypic stands along disturbed landscapes. Their voracious nature eliminates and prevents other plants from growing, which degrades ecosystems and acts as a physical barrier for animal and human movement in wild spaces. Currently, it is estimated that star thistle occupies over 15 million acres of California’s floristic zone, and Cordova Creek, along with the American River Parkway, is no exception.

An unseasonably wet winter ‘16-17, hot summer, and the recently disturbed soil from Cordova Creek’s construction, all aligned to create an ideal habitat for star thistle to thrive in. As a result, the population exploded to an unprecedented level that the Water Forum and our partners were unprepared to fully manage. However, we are using the knowledge that we learned from last year’s experience to guide our current management strategies.

Starting in April, work crews have diligently hand-pulled and removed thousands of young star thistle growing throughout Cordova Creek. Despite their hard work, star thistle persistently exists in a few problem areas. To help address these problem areas, the Cordova Recreation & Park District,  Soil Born Farms, and the American River Flood Control District kindly agreed to each donate a day of mowing at Cordova Creek. Mowing star thistle can be extremely effective as a removal technique if timed correctly – once the plants have matured, bolted, and are at ~10% flowering. Mowing during this critical period prevents seeds from developing, and, without rain, the plants will be unable to regrow and flower this season.

We appreciate the help of Cordova Parks and Recreation, Soil Born Farms, and the American River Flood Control District as we manage and control star thistle. We are confident that the combined efforts will ensure the success of Cordova Creek and the immense amount of ecosystem services that it provides to the community!

A Day on the Farm

Posted on Thursday, May 31st, 2018

A Rock-ing Day on the Farm

Over 1,000 visitors explored Soil Born Farms during what’s become a regional favorite event, “A Day on the Farm.” Soil Born annually coordinates this event to celebrate the seasonal opening

of their farm stand and allow visitors a chance to learn more about the farm and its surrounding environment, eat local food, play, and create.

The Water Forum hosted a booth at Farm Day, to highlight Cordova Creek and emphasize its abundant resources and unique history. As you might recall, from 2014-2017 the Water Forum collaborated with multiple organizations, including

 

Soil Born, to naturalize Cordova Creek which had previously been a cement-lined drain. Though only a year since completion, the native plants continue to grow and mature, and a charismatic beaver has built a dam and made Cordova Creek its home. Though the Water Forum and  Sacramento County Regional Parks are coordinating the maintenance in the early years, Soil Born Farms is poised to be the stewards of the creek.

In addition to raising awareness of the creek, the Fellows lead a children’s rock painting

booth. The perpetually crowded booth soon became enveloped in rocks of all colors and designs – unicorns, basketballs, marbleized, narwhals, and more! They were able to paint rocks to keep and to donate to Cordova Creek. Since Cordova Creek is only a year old, many of the plants are still quite young. To ensure that they grow big and strong, we want to make sure that they are visible. The rocks that the community helped decorate will be placed around the native plants as a border. The colorful, painted rocks will make them stand out so that they do not get accidentally stepped upon, pulled out, or mowed.

Next time you visit Cordova Creek, be on the lookout for colorful rocks sprinkled along the trail!
