Researcher Sacha Heath looks for insects on a "control" cottonwood.

Last week, I followed Sacha Heath down the Lee Vining Creek trail (and across the frigid stream, in my sneakers) to help count Lilliputians that live in trees. Sacha directed the Point Reyes Bird Observatory research in the MonoBasin for many years, but this season, for her Master’s thesis at Humboldt State University, she’s studying the impact foraging birds have on populations of herbivorous arthropods—i.e. plant-munching bugs—in cottonwoods. Bugs affect the growth of trees, of course, and Sacha picked the Mono Basin as her research location not only because she has an unparalleled knowledge of its riparian communities, but also because it’s a restoration setting—here, new growth is at a premium. The goal of the study is to assess ‘”the ecological service” birds likely provide. (more…)

After I finished my day’s data collections of stream flows for Mill Creek, I took the time to explore the Mill Creek bottomlands and the Black Point Marsh at the lakeshore. I eagerly hiked down the stream, bushwhacking through sagebrush, stopping to closely observe wildflowers, and frequently crossing the creek to observe curious Killdeer through my borrowed binoculars. Suddenly, completely out of the blue, I stepped onto the pumice sand of the beach and I was in a new world.

Where Mill Creek's water meets Mono Lake.

Not only had I had never seen Mono Lake from this angle, but following the trickle of Mill Creek water into the lake gave my weekly flow measurements and data collections new meaning. I am monitoring (more…)

It was hot and dry down at the Mill Creek culvert last Wednesday — perfect weather for a party! An invasive plant pulling party, that is.  Volunteers and interns enjoyed free snacks and sunshine as we worked, and whenever we needed a break the icy cold creek water invited us to wade right in.  After only two hours the four of us had uprooted sixty pounds of woolly mullein and sweet clover!

Defeating invasive weeds in the Mono Basin may seem like a lost cause, but even an hour or two of pulling can make a huge difference in (more…)

Undaunted by menacing storm clouds, a group of ten volunteers from Patagonia’s Reno store spent Friday afternoon uprooting invasive plants from sites along the Lee Vining Creek Trail. The task seemed pretty hopeless at first, but we removed a whopping sixty-six pounds of bouncing bet and cleared large sections of the trail. Thank you Patagonia!

There’s still a lot of work to be done, and we’ll be holding further “pulling parties” on three Wednesday mornings during the summer: July 28th, August 18th, and September 1st. Pulling Party Number 1 will take place from 9am to 12pm on Wednesday, July 28th at the Mill Creek culvert on Cemetery Road. Meet at the Mono Lake Committee at 9am to carpool to Mill Creek, or join us whenever you can at the culvert. Every little bit counts — stay for twenty minutes, an hour, or the whole morning! Email me with any questions. Watch out weeds!

Normally when the two of us head down to Rush Creek on Tuesday afternoons it’s an easy wade through ankle-deep water to reach the eastern bank. We hike through a willow thicket to a very old and overgrown utility road, and then the hunt begins for the six piezometers, or groundwater gauges, that hide in the brush on either side of the trail. At each piezometer we extend a tape measure deep into the throat of a PVC pipe until it hits water, and we record the depth. It’s often a struggle even to catch sight of the pool at the base of each pipe. But last week was different. (more…)

On Saturday July 3rd, Grant Lake Reservoir began spilling for the second time since the year 2000–it also spilled in 2006 after filling up in 2005.

Inflow is dropping as the melting snow runs out, although the warm weather is melting higher elevation snow, which could maintain high inflow for a few more days. Outflow is declining as well after peaking this morning at about 460 cfs (cubic feet per second). The spill peaked at 171 cfs on Thursday and Friday last week, but LADWP was still increasing the flow in the MGORD (Mono Gate One Return Ditch) until this morning. LADWP installed pumps at the spillway in order to ensure it would (more…)

I grabbed the flow meter and eagerly drove out to Lundy Canyon, where our beloved Mill Creek runs in its complicated course to Mono Lake. As the intern assigned to monitor Mill Creek this summer, I got to be one of the first people to see Lundy Lake Reservoir spill into the usually less-than-full creek bed.

Typically, Mill Creek is diverted at Lundy Lake to the SCE power plant. Some of that water is then diverted for delivery to water rights holders, but (more…)

For the last four days, Lee Vining residents and visitors strolling down the Lee Vining Creek Trail could hear boulders knocking against each other over the roar of the whitewater in Lee Vining Creek. The “clunking” sound is coming from the creek—it is the sound of large “bedload” moving—rocks moving along the bottom.

Yesterday Lee Vining Creek peaked at 512 cfs. This is the highest flow in the creek since 1998. Maximizing the peak flow below the DWP diversion dam is the primary tool used to restore the creek from damage done by (more…)

The Los Angeles Department of Water and Power submits annual compliance reports in May to the State Water Resources Control Board. The May 2010 report was recently distributed and we’ve posted each section on the Mono Basin Clearinghouse. You can download the cover letter, the status of compliance report, the operations plan, the fisheries report, the tributaries report (geomorphology, hydrology, and vegetation), and the waterfowl report.

The Final Synthesis Report was released this week! You can read it below. You can also download the 58 MB appendices, which contain the Stream Scientists’ responses to comments, on the State Water Board’s Website. You can find the draft reports and additional information and links in our Streamflow Center. (more…)
