LADWP: Emergency Runoff Management Activities

April 12, 2017

BISHOP, CA – The Los Angeles Department of Water and Power (LADWP) is working proactively to prepare for the arrival of anticipated massive runoff water resulting from this year’s near record snowpack in the Eastern Sierra Nevada Mountains. These efforts are in partnership with Inyo County, the Inyo Sheriff’s Department, Bishop Police Department, Cal-Trans, Southern California Edison and others, as a member of the Inyo County Interagency Emergency Preparation team.

Work to prepare for the anticipated high water flows began in late February. The efforts have been assisted by an Emergency Declaration from the Mayor of the City of Los Angeles to allow LADWP to take immediate steps to protect infrastructure and aid in managing flood waters while also protecting public safety. Inyo County issued a similar declaration.

To maximize the beneficial use of runoff water to the fullest extent, LADWP is spreading water throughout the aqueduct system to replenish local groundwater aquifers. Current spreading is moderate and will increase as runoff occurs in larger quantities later this spring and summer. LADWP is also maximizing flows in the LA Aqueduct by lowering reservoirs to create more storage space for runoff water and supplying the City of Los Angeles with aqueduct water in place of purchased water and groundwater wherever possible to manage excess flows. Further, LADWP crews are hard at work preparing, cleaning, and repairing water conveyance ditches, spreading basins, sand traps, and other facilities located on City of Los Angeles property, areas controlled by LADWP, and along the Los Angeles Aqueduct, in order to manage the anticipated runoff. 

Water that exceeds what can be spread to recharge local aquifers and which does not make it into the LA Aqueduct system will end up on the Owens Lakebed, the natural terminus point for waters flowing down the Owens River. Once there, it will add to the existing 30 sq. miles of saline brine pools and is expected to cause significant flood damage to dust control infrastructure managed and constructed by LADWP over the past 17 years. These measures, spread over nearly 50 sq. miles of dried lake, have effectively reduced dust pollution in the area by 96 percent. Damage to these dust control areas may result in increased air pollution that could threaten the health of the public after the runoff evaporates in 12 to 18 months.

LADWP is also concerned by the potential of water overflow in and around the towns and communities of the Eastern Sierra and is actively providing assistance in preventing and controlling runoff that could impact the public. Emergency assistance will be provided on lands throughout the valley should flooding threaten the property of a partner agency or the public.

“Inyo County is no stranger to emergencies and disasters,” Inyo County Sheriff Bill Lutze said. “Our resilience comes from a strong unified command made up of local, state and federal agencies as well as a public that is proactive in emergency preparedness. We continue to be grateful for our strong working relationships with our allied agencies, including Department of Water and Power, as well as with our residents.”

In order to keep the public informed of the steps being taken to manage runoff to the greatest extent possible and minimize the impact to dust control measures, LADWP will issue regular updates of its runoff management efforts.

New Bands Confirmed!
We're pleased to announce two more confirmed acts for Millpond 2017:

Thomas Mapfumo & the Blacks Unlimited
Thomas Mapfumo was born in Marondera, Zimbabwe in 1945. His early childhood moments, saw him exploring an interest in traditional music and instruments (ngoma, hosho, and mbira) which came from his grandparents who were avid musicians in the village. His growing interest in music coincided with a growing awareness of the social and political inequalities of colonial Zimbabwe. Mapfumo founded the Blacks Unlimited in 1978, pioneering their own genre of music known as "Chimurenga." Chimurenga music became a symbol for the struggle against injustice as it assumed a distinct and threatening presence in war-torn Rhodesia.

  When Zimbabwe became independent in 1980, Mapfumo shared the celebrations stage with the Jamaican reggae legend Bob Marley, opening the doors to international fame. However, to the surprise of many, the same censorship and repression of colonial Rhodesia also visited Mapfumo in independent Zimbabwe. In 2000, he relocated to the USA and continued with his music.

  In October 2012, Mapfumo, also known as the "Lion of Zimbabwe," entered the Afro-Pop Hall of Fame, getting the chance of a lifetime to perform at Carnegie Hall. We are excited to be bringing Thomas Mapfumo and the Blacks Unlimited to the Millpond Stage for the 2017 festival.

Caltrans: Annual Litter Pickup Day

Caltrans Annual Litter Pickup Day

Bishop – The California Department of Transportation (Caltrans) is joining forces with California Highway Patrol, City of Bishop, County of Inyo and volunteers Thursday, April 13th for the annual California Statewide Litter Collection, Enforcement and Beautification Day in an effort to increase public awareness on the volume and cost associated with removing trash along state highways.

Litter in California is an ongoing problem, which results in significant economic, social, and environmental costs.  Litter is aesthetically displeasing, presents a range of threats to human and ecologic health, and affects the quality of life for the citizens throughout California.  Litter increases the risk of personal injury to our employees, the threat of fire by discarded cigarettes along the State Highway System, the spread of diseases in our communities, and can threaten wildlife and pollute California’s waterways.  These impacts are real.

Last year, Caltrans spent $76.5 million on litter removal throughout the State Highway System.  Almost 153,000 cubic yards of litter (about 9,562 garbage trucks) were collected and disposed.

Maintenance crews will be picking up litter in counties serviced by Caltrans District 9 on Thursday, April 13th and also on Thursday, April 20th. Residents in Inyo, Mono and eastern Kern counties will see crews working on highways and freeways throughout the day removing litter and debris discarded by the public. Highway message boards will remind motorists "Don't Trash California."  Please be attentive of extra workers on the highway picking up trash and remember to "Slow for the Cone Zone.”

The public can help by participating in the Caltrans Adopt-A-Highway (AAH) Program.   The Adopt-A-Highway Program provides an avenue for individuals, organizations, or businesses to help maintain sections of roadside within California’s State Highway System.  More than 120,000 Californians have cleaned and enhanced over 15,000 shoulder-miles of roadside.  Participation allows the public to adopt sections of highway for beautification projects, such as litter removal, vegetation control, graffiti removal, and tree and shrub planting. 

For more information on the Caltrans Adopt-A-Highway Program, please visit or call Tom Scott, District 9 Adopt-A-Highway coordinator, at (760) 872-5202.

Inyo 350: Earth Day March Planned

‘March for the Earth’ to be Held on Earth Day – April 22

Earth Day will be celebrated around the globe on Saturday April 22. This marks the 47 th anniversary of a day set aside to raise awareness and to educate ourselves about our planet, our environment and all the challenges and opportunities that come along with taking care of it. It is always a day to come together to celebrate our amazing planet Earth.

This Earth Day the newly formed local group INYO350, in conjunction with its sister organization 350 MONO and the Sierra Club, will be sponsoring a ‘March for the Earth’ in Bishop. The March will be sponsored in solidarity with the international ‘March for Science’ and the ‘People’s Climate March’ in which people all around the globe will be gathering and marching to celebrate science and to promote an awareness of climate, jobs and justice.

All are welcome to join in this celebratory ‘March for the Earth.’ The event will start at 9:00 a.m. with a Gathering in the back of the Bishop City Park in the picnic pavilion across from the Senior Center. The Gathering will include songs, a blessing, speakers and acknowledgement of the amazing scientists working here in the Eastern Sierra. The March will take place from 9:30 – 10:30 along Main Street in downtown Bishop. The March is being planned to end in time for people to join in on other Earth Day events taking place in the Bishop City Park and at the Paiute Shoshone Cultural Center.

INYO350 is part of which is currently active in 188 countries. As an international organization dedicated to promoting environmental protection and climate awareness, has worked to build a global climate movement from the grassroots up. The science behind “350” is that if we wish to maintain our planet in a condition similar to how it has existed since the development of human civilization then we need to decrease carbon dioxide in our atmosphere to 350 parts per million (ppm.) We are currently at 400 ppm. The time is now to do all within our power to reduce carbon emissions and reduce our carbon footprint.

Locally INYO350’s work revolves around action groups that are focused on the Environment, Social &; Economic Justice, and Healthcare. Shawn Louth, President of INYO350, states, “There is much to be done right now. I encourage all who are interested and want to learn more to attend our monthly meetings and become involved. Working together we are taking concerns and transforming passions into meaningful actions.” The members of INYO350 are committed to devoting time and positive energy to the achievement of their mission which is “To promote environmental protection and social and economic justice through policy influence, education and direct action.”

The Sierra Club was founded by legendary conservationist John Muir in 1892 and is now the nation’s largest grassroots environmental organization – with more than two million members and supporters including nearly 1,000 in the Eastern Sierra. As local Sierra Club Eastern Sierra Organizer, Fran Hunt, notes, “The March for the Earth is a celebration of our planet; the clean air, water and healthy landscapes we treasure in the Eastern Sierra; and the scientists who study and help us safeguard these natural wonders. Our goal is to advance both social justice and environmental awareness.”

For more information on INYO350 or the March for the Earth please email them at and follow them on Facebook or contact the Sierra Club at or follow the local Range of Light group on Facebook.
