According to Amanda Parsons at LADWP, 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.
Emergency Runoff Management Activities undertaken by LADWP as of April 11, 2017, include:

According to Lt. Bill Dailey at the CDFW law enforcement division, on Feb 24 2017 at approximately 1500 hours a hunter who had been hunting near the north
shore of Mono Lake for coyotes had a mountain lion encounter. The hunter was wearing
camouflage clothing lying on his stomach on top of a small knoll blowing on a distressed rabbit
call when he heard a noise behind him. As the hunter looked over his shoulder he saw a
mountain lion had jumped in the air and was coming toward his head. While lying on the
ground the hunter threw up his arms in order to protect his head. The lion landed on the
hunter’s head, sprung free and ran towards the north. The hunter, being in fear for his life fired
two shots striking the lion. He then returned to his vehicle and notified DFW Officers.
The hunter sustained a minor injury to the back left side of his head that did not break skin.
The hunter sought medical treatment from Mammoth Lakes Hospital and initiated the rabies
shot series. Evidence from the scene was collected and sent to DFW’s Wildlife Investigations
Lab in Sacramento. The lion will be necropsied and tested for zoological diseases including
An analysis of the tracks found at the scene of the incident left a very clear picture of the event
and how it unfolded. It appeared the lion was responding to the distressed rabbit call and the
encounter resulted in the hunter possibly being mistaken for prey by the lion. Given the
circumstances, the lion likely mistook the hunter for an injured rabbit and given the suddenness
of the attack the hunter responded in fear for his life.
The Department will not be filing any charges for the take of the mountain lion.
Cash will no longer be accepted at many California Department of Fish and Wildlife branches. As of January 1st, 2017 the California Department of Fish and Wildlife’s License and Revenue branch, and regional license counters will no longer accept cash as payment for new CDFW issued licenses. Payments may still be made by check, money order, or any credit or debit card with the Visa or Mastercard logo. Cash transactions will, however, continue to be accepted through authorized local sales agents.
Also, according to CDFW, the deadline for deer tag reporting will pass with the start of the new year. Tag holders who fail to report will be charged a non-reporting fee of $21.60, which will be added to their first deer application or tag purchase for the 2017-2018 season. To submit a harvest report go to the website at https://www.wildlife.ca.gov/Licensing. Next, select the appropriate item to report. Submission of your harvest report may require a document number which is located under the bar code on your tag or report card. To avoid errors, answer the questions in the order that they appear on the page. After you submit the report you must record the confirmation number and retain it as proof of reporting.
Mountain lion seen roaming near Line Street in Bishop.

California Department of Fish and Wildlife and Inyo Count Sheriff’s Office have recently been notified of mountain lion sightings in the West Bishop Area located near Line Street. According to calls received by CDFW and Inyo Sheriff’s Department the mountain lion has not yet displayed aggressive behavior. Mountain lions are native to the region and are sighted periodically in and around the Bishop area. CDFW Biologists and Game Wardens are monitoring the mountain lions activities.
An estimated 4 to 6 thousand mountain lions live in California. Typically they avoid interaction with humans and will move from the area in a couple of weeks. CDFW has a non-lethal policy concerning mountain lions whenever possible and in some rare occasions will relocate the animal. But public safety is the main priority in the event of an attack or any threat to humans.
CDFW is advising residence in the area not to take matters in their own hands. To report a mountain lion sighting call Bishop CDFW at 760 872 1171 or Inyo County Sheriff’s office at 760 878 0383.

The California Highway Patrol and the California Department of Fish and Wildlife (CDFW) will be holding checkpoints this weekend. The CHP sobriety checkpoint is Saturday, April 25th on highway 395 at the south end of Bishop. The DFW checkpoint is scheduled for Monday, April 27th on highway 108, north of Bridgeport.
In recent years, Fish and Wildlife has conducted a similar checkpoint south of Bishop, however this year they are shifting their focus to Mono County. According to CDFW officials their checkpoint will, “Promote safety, education and compliance with laws and regulations. The wildlife checkpoint is being conducted to protect and conserve fish and wildlife, and to encourage safety and sportsmanship by promoting voluntary compliance with laws, rules and regulations through education, preventative patrol and enforcement. All anglers and hunters will be required to stop and submit to an inspection. CDFW officers will also be providing informative literature about the invasive quagga mussel and New Zealand Mudsnail.”
The Saturday CHP checkpoint will be staffed by officers who are trained in the detection of alcohol and or drug impaired drivers. Officers will be on site providing on the spot assessments of drivers suspected of drug use. Officers will be equipped with state of the art hand held breath testing devices with provide an accurate measure of blood alcohol concentrations of suspected drunk drivers.
Funding for the CHP checkpoint is provided to the CHP by a grant from the California Office of Traffic Safety, through the national highway traffic safety administration.
