Myself, along with three other volunteers, began the scout at the Altadena Crest Trailhead in Altadena. We hiked for about two and a half miles on the Gabrieleno Trail along the Arroyo Seco to Gould Mesa Trail Camp, eventually turning around somewhere between Gould Mesa and Paul Little Picnic Area. The Arroyo is beautiful right now and as always, a very thriving ecosystem. We saw several California newts, who are mating right now and mountain yellow-legged frogs.
We stopped several times along the way making several notes about trout habitat and riverine conditions. We saw several things that made me confident of the existence of rainbow trout in the Arroyo. Here are some of the major habitat features that we discovered in several key habitat categories.
This central section of the stream currently possesses all of the necessary habitat requirements needed for native southern California trout to thrive; cool and clear water, stable undercut banks, clean gravel beds with little to no silt, overhanging vegetation, structural/habitat diversity and the food that trout eat.
The stream is flowing well about 5-10 cfs and the water temperature is cool. The banks along this section of the stream are undercut creating sufficient pool depth for trout to live in during the drier summer months.
Additionally, the roots of white alder trees which grow abundantly along the stream provide strong support along the banks. The gravel beds are clean and soft creating high quality habitat for trout to possibly spawn in the future. Canopy cover above the stream (overhanging vegetation) was almost always 50-to-75 percent, which keeps dissolved oxygen adequately high for native trout to thrive.
Lastly, many of the key components of trout dietary needs were present as well. These include terrestrial insects, spiders, midges, dragonflies and water boatman bugs.
Perhaps the most promising feature was the discovery of several two-to-four-foot-deep pools created by in-stream structural diversity, such as boulders and large woody debris. These pools are essential for trout survival and illustrate the important function that downed logs and boulders play in providing high quality for trout.
I will keep you all updated on the next “Trout Scout” and any possible trout sightings!

She was lying on her back on the bottom of a pool, pushed by the flow against a rock. Bruised, scales falling off, scrapes all over her body, she was barely breathing. Gently holding her face into the flow, she gasped for air and hung limply in my hands. I could feel her muscles twitch and contract, but she could not swim at all. When I let her go, she sank to the bottom on her back and rolled with the flow on her side, up against my feet, unable to orient herself.
At 23 inches, she was a full-grown anadromous steelhead that had fought her way upstream against the current in search of a place to spawn. The creek was wondrous after all the winter storms, with steady flows cascading over rocks, providing a background music calling her upstream to find a good place to lay her eggs.
For several minutes we stood and discussed what to do. She was clearly not going to recover and survive, but she was not quite dead yet. It was just heartbreaking to think of losing this fish, one of only four anadromous adults known to have returned to the creeks so far this year in all of Southern California.
What went wrong? How did she get so banged up? Was the flow too strong? Was she too old and tired, having waited too many years for the rains to come?
She died in my hands. I brought her battered body back to teach us and help us learn to tell her story. Her scales will tell us her age. Her DNA will give us insight into her ancestry. She was not one of our tagged fish, but from somewhere else. Only 18 eggs, an empty stomach. The promise of the future for southern steelhead took a big loss today.

Editor’s Note: Dagit and the RCDSMM have permits to monitor and handle these endangered fish. Only permitted biologists are allowed to handle them. There is a substantial fine per fish (around $25,000) for harassment or taking one from the water, if not permitted.
In a political time, it’s once again time to get political.
If you thought that suction dredging mining was banned for good from the East Fork of the San Gabriel River outside Los Angeles, and other once-pristine California waters, think again.
You can read my coverage from 2012. I thought it was a done deal that the California Department of Fish and Wildlife would be allowed to stop illegal activities even on federal lands, even within a national monument. But Pasadena Casting Club Conservation Chair John Tobin recently alerted me that, sadly, it might not be the case in the future.
As Tobin wrote in an email, “California Senate Bill 637, effective January 1, 2016, created a path for the statutory prohibition against suction dredge mining on our California streams to be lifted.”
Currently, there’s a case before the California Supreme Court challenging whether state environmental law that makes a particular mining claim on federal land commercially impractical preempted by the federal mining laws, according to the brief.
In other words, can California through its police power protect the environment, even on federal land?
For anglers, this means a choice between antiquated, destructive machinery disrupting the stream bed and scattering whatever trout may have thrived there for a largely recreational activity. Imagine trying to wet a line next to one of these contraptions. Imagine the downstream effect to the water.
You use our national lands to enjoy one of the best parts of your recreational life. Help make suction dredge mining a thing of the past.

Less than an hour’s drive from here, up in those dry and dusty San Gabriel Mountains, are three rare and precious wild trout streams, the West, North and East forks of the San Gabriel River.
Under arbors of alder, sycamore and oak, they run clear and cold all year long, despite drought, and harbor wild rainbow trout. Some of the rainbows are direct descendants of steelhead trout, which went to and from the sea for eons before the dams were built.
The streams are also home to some threatened and endangered creatures, including the Santa Ana speckled dace, that exists only in the Los Angeles basin. These flows are always under pressure, and not just from the lack of water. They frequently suffer from overuse by crowds of visitors, some of whom trash them and others who damage them with illegal gold mining and with what the forest service calls “recreational dam building.”
The forest service has long been hard pressed to protect them: not enough money, and not enough staff.
The many people who know and love these streams were naturally excited when President Obama designated the National Monument in the fall of 2014, anticipating that plans and resources would be developed to better protect these waters. And so the fishers, the hikers and the mountain bikers, together with professional fishery experts, weighed in during the requisite public comment period to tell the forest service what they thought should be done for these streams in the new San Gabriel Mountains National Monument Plan.
At the end of that process, the forest service produced a summary of the comments and an outline of the issues and concerns they determined should be the focus of the plan. Sadly, the outline for their management plan does not include any focus on these streams.
Consequently, in accordance with the forest service’s planning policies, all of the stream-specific comments and recommendations that were submitted by the public were ignored. They will not have an influence on the management plan for the national monument.
If this concerns you, let the forest service know:
Contact Justin Seastrand, Environmental Coordinator, Angeles National Forest, at firstname.lastname@example.org, or Superintendent Jeffrey Vail, at JVail@fs.fed.us.
Don’t have to wait for the next public comment period later this winter or spring, when part of the environmental assessment will be published. It may be too late by then.

“We’re hoping for the best, but we’re going to continue to prepare for the worst,” Los Angeles Mayor Eric Garcetti said. “… If [the river] floods, there is risk of significant damage, not to mention real and immediate danger to Angelenos.”
If you’ve been down to Glendale Narrows, you know that the river encasement is already high, 20 feet, according to the U.S. Army Corps Los Angeles River Ecosystem Restoration Feasibility Study so what could a temporary four-foot-high barrier accomplish that isn’t already there? And for $4.5 million?
But the more vexing part of this emergency solution is “removing debris.” If the Corps removes the islands and plant life that dot the area, you can kiss the only structure fish have goodbye. It’s also a very healthy bird habitat. The NBC story indicates this is already taking place. Here’s the 2013 draft redesign plan for that area:
Existing Channel Features – The existing trapezoidal channel within the sub-reach varies from grouted rock to concrete paved channel, is 310 feet wide from the top of bank and 20 feet high from the invert.
Preliminary Channel Design – As seen in Figure 4.12, ” Cross-Section 5, Los Feliz Boulevard to Glendale Freeway,” the proposed design would construct four concrete terraced planters in the left/east bank of the channel slope. The right/west bank of the trapezoidal bank would be replaced by a 22-foot-high vertical retaining wall with subdrainage under the invert slab, which would meet the existing top of bank. Two riprap toedowns would be constructed below the channel bottom and bank. The first riprap toedown would be constructed on the right/west bank and the second that would include bank protection, would be located on the left/east bank. Two 16-foot-wide asphalt concrete maintenance roads would be constructed on the land of the retaining walls on the top of bank. The existing cobble/soft bottom would be protected in place and expanded 27 feet towards the proposed right/west bank of the channel.
