Milkmaids (Cardamine californica) are among the first flowers to bloom in the Santa Monica Mountains in the early Winter. The plant prefers the the coast live oak understory, and the four-petaled white blossoms stand out brightly in the shade of the trees.
These are along the Serrano Canyon Trail in Pt. Mugu State Park. This photo was taken February 4, 2017, but milkmaids were blooming on this trail as early as January 1, 2017.
As of yesterday Downtown Los Angeles (USC) has recorded 8.80 inches of rainfall for both the Rainfall Year (July 1 – June 30) and Water Year (October 1 – September 30). By either measure Los Angeles rainfall is well above normal, and with three well-advertised storms in the forecast it looks like Los Angeles rainfall could remain above normal for at least a few weeks.
Even if it has been a bit wet — and muddy — it’s been great to have a more normal rain season. The rain has been very beneficial and has impacted the drought, at least in the short term. Just how much a continued wet rain season would impact the drought in the long term is a question that has to wait for future analysis.
There has been a five year precipitation deficit of nearly 36 inches at Downtown Los Angeles (USC). It’s hard to appreciate the size of this deficit while running in the rain, splashing through puddles, and trying not to slip in the mud. One tangible indicator of this deficit is that despite above average rainfall, many creeks in the Santa Monica Mountains and Simi Hills have remained dry or are barely flowing. Some have been dry for years.
Update Wednesday, March 1, 2017. The atmospheric river event on February 17 produced high flows on many local streams and many of these streams continue to flow. Rainfall totals in Los Angeles, Ventura and Santa Barbara Counties for the storm generally ranged from 4 to 8 inches with some higher totals recorded. On subsequent trail runs flooding, debris flows and erosion were noted in Upper Sycamore and Blue Canyons in Pt. Mugu State Park. Remarkably, some groundwater monitoring stations in Santa Barbara and San Bernardino Counties remain well below normal.
As of February 28, 2017, Downtown Los Angeles (USC) had recorded 18.50 inches of rain for the Rain Year and Water Year. This is 165% of the normal amount of 11.24 inches for the date, and 124% of the normal amount of rainfall for an entire year. This is the wettest Rain Year (July 1 – June 30) and Water Year (October 1 to September 30) to date since the very wet year of 2004-2005.
Update Tuesday, January 24, 2017. From Wednesday, January 18 through Monday, January 23, Downtown Los Angeles (USC) recorded 5.53 inches of rain, bringing the Rain Year and Water Year precipitation totals to 14.33 inches. This is 217% of the normal amount of 6.65 inches for the date, and 97% of the normal amount of rainfall for the entire Rain Year. It has been the wettest start to the Rain Year (July 1 – June 30) and Water Year (October 1 to September 30) since the very wet year of 2004-2005. There were high rain rates on Sunday, January 22, and Upper Las Virgenes Creek did finally flow for a period of time.
Update Saturday, January 21, 2017. From Wednesday, January 18 through Friday, January 20, Downtown Los Angeles (USC) recorded 2.53 inches of rain, bringing the Rain Year and Water Year precipitation totals to 11.33 inches. The average annual rainfall for Downtown Los Angeles is 14.93 inches. The rain, which was heavy at times on Friday, produced some flooding, rockslides and debris flows. Both branches of upper Garapito Creek are flowing as a result, but Saturday afternoon Upper Las Virgenes Creek was still not flowing.
Upper Las Virgenes Creek – February 22 the flow on Upper Las Virgenes Creek near the Cheeseboro connector and the two downstream crossings was enough that you couldn’t cross without getting your shoes wet. Previously, on January 24, there was no flow near the connector and only a slight trickle downstream. On January 21 the creek was not flowing and there was no evidence it had flowed during a recent storm.
Garapito Creek – On Saturday, January 21, 2017, both branches of upper Garapito Creek were nice burbling brooks. Previously, on January 15, the north branch was just starting to flow, but the south branch was dry.
Upper Sycamore Creek – Flash flooding, debris flows and erosion occurred on this creek following the heavy rain on February 17-18. Nearly 6 inches of rain was recorded at Circle X Ranch, which is also in the western Santa Monica Mountains. Previously, was flowing on February 4, but not on January 1, 2017.
Serrano Creek – Was flowing on February 4, but not on January 1, 2017.
If the wet forecast holds will these streams start to flow? We’ll see!
From today’s New Year’s Day run over Boney Mountain to Sandstone Peak and Serrano Valley from Wendy Drive.

From this morning’s out and back run from Satwiwa (Wendy Drive) to Mugu Peak.
A few wildflower photos from a recent run to Serrano Valley and La Jolla Valley in Pt. Mugu State Park.
The title photo is Padre’s shooting star (Primula clevelandii, formerly Dodecatheon clevelandii) along the Old Boney Trail. Click an image below for more info and to display the image full-size.
Illuminated by the rising sun and partially enveloped in cloud, Boney Mountain’s Western Ridge looked so inviting I thought about abandoning my planned run and climbing the ridge instead.
Pt. Mugu State Park is a great place for long, self-supported trail runs. The scenery is superb, the trails are generally in good condition, and water is usually available in several locations.
Today’s run took me to two of the most scenic areas in the Park — Serrano Valley and La Jolla Valley. This archived PDF map shows many of the trails in the area. The Wendy Drive trailhead is in the upper right corner of the map. La Jolla Valley is marked and Serrano Valley is near the “PARK” in the label “POINT MUGU STATE PARK.” Also see the Pt. Mugu State Park maps on VenturaCountyTrails.org
The marine layer kept the temperature cool for most of the run, but the sun finally broke through as I ran up Sycamore Canyon on the Two Foxes trail, on the way back to the Wendy Drive trailhead.
Although much of the run was overcast, a good selection of wildflowers added some bright color to the cloudy day.
