Lots of links to their work if you google ‘owens lake ch2m hill’, but nothing on their website about owens lake… hmm wonder why, or why not?
Ecosystem Sciences was been working since 1993 to develop and implement restoration plans for the Owens River and the Owens Valley from Mono Lake to Owens Lake, some 250 miles of river and over 350,000 acres valley watershed. The city of Los Angeles diverted surface and groundwater from the Owens River Valley in the 1930’s through an extensive aqueduct system. This resulted in the dewatering of the lower Owens River for over 60 miles and attenuated reductions in groundwater, riparian, and wetland habitat, as well as created losses in fish, wildlife, and other natural resource values throughout the watershed.

Wetland vegetation type inventory, Owens Delta, California. 2000. Conducted a very detailed inventory of wetland vegetation types for about 7,335 acres at the inlet to Owens Lake. Conducted for CH2MHILL, Los Angeles, CA.
Wetland vegetation associated with springs in Owens Valley, California. 1999. Mapped vegetation in the vicinities of over 100 springs in Owens Valley. Conducted for Ecosystems Sciences, Boise, ID.

Don Sada, Aquatic Ecologist,
Saltgrass (Distichlis spicada) was determined best for the dust control plan, and in 2000, seed was collected around the lake bed and aqueduct. 50 acres of saltgrass seed farms were established in the Owens Valley and at S&S Seeds’ test plots in Los Alamos.
By cultivating Owens Valley saltgrass, S&S teamed with Earthworks Construction & Design habitat consultant Margot Griswold and CH2M Hill project design engineers to assist the DWP in its efforts to turn Owens Lake into an area safe for humankind.

Phase 7 (in progress 2010)
Owens Lake Dust Mitigation Phase VII Design. For the Los Angeles
Department of Water & Power, Mr. Boyd is currently overseeing the Phase VII design of shallow flooding and moat and row dust mitigation measures as leader of the CDM Technical Review Committee for this project. He is providing technical guidance to the design team and oversight.
Barnard’s dust mitigation project on the dry lakebed at Southern California’s Owens Lake continued at a good pace this fall. On this Phase 7 project for the Los Angeles Department of Water and Power, we are mass grading, fusing and installing lateral irrigation
piping, and performing concrete work. In August, we met our project’s intermediate milestone. Crews finished the roads and berms in October; we will wrap up the laterals by year’s end. Work
on above-ground mechanical turnout piping continues through December, then leaving only the electrical, SCADA control, start-up and testing items. The extreme heat of summer at this remote location has now been replaced by rising water tables. And, in early October we experienced over 200 earthquakes near the office, the largest registering 5.2 on the Richter scale. In addition to the LADWP, we’re working with CDM (engineer) and subcontractors ESC on electrical; Double E Construction in concrete work; G&J and Archer trucking enterprises in hauling riprap and embankment material; Kleinfelder in QC testing; and Walker River Construction in surveying.
Owens Lake Dust Control Program, Shallow Flood Area Electrical Distribution System Design, Department of Water And Power, City of Los Angeles
As Principal Subconsultant to CDM, LEE & RO is responsible for the electrical distribution system design for five Moat Row areas of the $200 million Dust Control Program projects undertaken by LADWP. The LEE & RO scope of work includes electrical distribution systems, including both the North and South Sand Sheet 4,800 volt and 480 volt systems supporting existing and new dust control facilities. The design scope includes single line diagrams, panel board schedules, site plans/turnouts, wiring plans and details, pipe heat tracing, and miscellaneous electrical details. The project construction is scheduled to be complete in summer of 2010.

Is anyone aware that Sungro Minerals, Inc. is planning on opening an open gold mining operation on Conglomerate Mesa?
I can’t believe that a mining operation that involves blasting, digging, dumping ore in trucks, trucks hauling ore and ore crushing would be allowed so close to Owens Lake.
All this new dust could/would destroy all the efforts that have been done to control dust.
Conglomerate Mesa is the peak adjacent to the historic Cerro Gordo mining district.
Sungro’s press release is here: http://mwne.ws/nlrhey
I don’t have the time to chase after the EIR or permits on the project, that’s what google is for…
