LA River Historical Flows, circa 1879

February 3, 2022 § 5 Comments

Just a quick note to add some perspective to a recent LA Times article about treated wastewater discharged into the LA River and the possibility that this could be reduced. The amount of water in the river in its “beforetimes” has been the subject of quite some argument that sometimes gets trotted out to justify modern decisions. So here’s documentation from the State Engineer William Hammond Hall circa 1877 (Emphasis mine):

The drainage of the Los Angeles river after leaving the Sierra Madre Mountains is received into the large basin of the San Fernando Valley, whose soil is gravelly and porous, but probably underlaid with an impervious substration(sic) of clay or rock , and acting as a great sponge, it holds the water it receives and gives it off slowly. This valley is shut in on the south of the coast range at the foot of which the river runs, finding an outlet through the hills by a narrow gap just above the city of Los Angeles. The streams emptying into the basin are the Paloma, the Pacoima, the Tujunga, and the Verdugo, of which the largest is the Tujunga. Like all the mountain torrents which descend from the Sierra Madre, they have a very rapid fall, and on reaching the valley spread out into broad “washes”, whose beds are composed of boulders gravel and coarse sand. In flow they flow entirely across the valley to the Los Angeles river, but in summer the water barely emerges from the mountains, and sinks from sight in the porous channels. The Arroyo Seco, another large tributary having the same characteristics as the other mountain torrents, enters the river at the city of Los Angeles.

In May last the discharge of the river at the mouth of Tujunga Wash ten miles above the city, where the upper dam of the Los Angeles irrigation system is located, was 24 ½ cubic feet per second. This amount was augmented by about 54 cubic feet per second from springs rising in the bed of the river at various points between this dam and the city. The total available supply therefore was about 78 ½ cubic feet per second. An amount which is but little diminished during the summer months.

Below the city the river is broad, shallow and sandy, and only upon rare occasions does the water ever find its way entirely to the sea, but is absorbed by the thirsty sand.

Which are at the State Archives under AC 91-06-10

(Schuyler FWIW is the actual person taking the measurements and writing the notes…The dam mentioned is near present day North Hollywood. That total flow description is for flow approximately near Figueroa Street in Northeast LA – He doesn’t mention any inflow from the Arroyo Seco, so it’s hard to say if he was measuring above or below that)

It’s a shame the terms of contemporary debate are so narrow that serious people only argue about how much life support (treated sewage aka used imported water) to give the river – if any. In some parallel universe there is perhaps a dialogue being had about recharging groundwater, reconnecting floodplains, and removing or reducing the effect of dams on river flows… but for us, in this universe, we don’t even have in the English language much of a functioning subjunctive tense with which to describe the possibilities that the river (and we) deserve, without being laughed out of the room.

But the subjunctive still gives us this: Long live the river!

Dry weather diversions – memories up a sh*t’s creek

December 29, 2021 § 3 Comments

Yesterday’s post hurt my brain to write, and it hurts my brain a little to re-read. OK, it hurts my brain a lot. So I suspect it’s not fun for anyone else either. I wish it could be more straightforward.

And then I woke up this morning realizing I wasn’t done with the subject yet. Ugh.

So if this issue of buried streams in the crossfire of clean water regulations and local governments liable for compliance is pertinent to you, bear with me. If you live in a park poor area with buried streams (Angelenos, that’s basically you), it’s pertinent.

A buried creek’s dilemma: to be daylighted or drained?

December 28, 2021 § 3 Comments

[Opening digression: I was just texted an image predicting rainfall for LA for the next few days – it looks like you could get hammered (rainfall-wise – what you do with alcohol I have no predictions for), so this post may seem ironic, misplaced, bad timing? You’ve got a trough heading your way and if it doesn’t keep moving…well let’s just hope that it does. The focus of today’s post is dry-weather flows…]


To those of us who recognize stormdrains (or, some of them) as body-snatched creeks, and who long for a water management approach that would incorporate daylighting or naturalization of concreted waterways and nature-based treatment that doubles as streetside landscaping, floodable parks, greenways, etc., well, prepare to be disappointed. Or enraged? Whichever, it’s a familiar feeling. At least we’re not alone on this.

The City of LA recently issued an IS/MND (Initial Study/Mitigated Negative Declaration) and awarded a contract to start work on diverting low flows from certain stormdrains. The low flows – aka urban slobber in some circles – would be pumped from the storm drains into the sewer system, so that they can be treated for pollutants. From there, like the rest of the region’s wastewater, it either gets discharged into flood control channels rivers, is infiltrated to groundwater, or reused (such as purple pipe irrigation). So you can see how it closes some loops and ticks some sustainability boxes.

In every bottle, a creek…

February 2, 2017 § 4 Comments

arrowhead-bottle-with-springs-list

Next to the snow-covered mountain on each Arrowhead bottle, is a list of “mountain springs” within.

The Arrowhead landmark in the foothills of the San Bernardino Mountains.

The actual Arrowhead landmark in the foothills of the San Bernardino Mountains.

In every bottle of water is a creek, and there is actually a good chance it may be a California creek, as the map in this link indicates: “Lots of your bottled water comes from drought zones.”

This is something I think about every day when I walk by the water dispenser at my office. I look at the snowy mountain top on the label, and mentally compare it to the actual Arrowhead landmark, in the foothills of the San Bernardino Mountains, which I drive by each week. This iconic landmark is made of coastal sage scrub plants: white sage, black sage, california buckwheat, and others (Meek, 2007). Ironically, what makes the arrow stand out from the surrounding chaparral is the grey foliage that advertises the ability of these plants to survive drought.

Our remaining native ecosystems hang on a very delicate balance, and surface water and groundwater play an important role in maintaining this balance. This is just one of the reasons I feel alarmed when I see the list of “mountain springs” listed on the side of Arrowhead bottles. Because I suspect the other places on this list do not look anything like the snow-covered mountain on that label!

Steve Loe, a retired San Bernardino National Forest biologist, speaks to a packed house.

Last Sunday, I went to a community hearing sponsored by The League of Women Voters and Save Our Forest Association to learn how Nestlé’s extraction of water from the San Bernardino National Forest impacts Strawberry Creek, its riparian ecosystems, and our local groundwater. Speakers addressed a packed house at the Senior Center in Twin Peaks.

Strawberry Creek is the creek associated with Arrowhead Springs, after which Arrowhead water is named. It is located in the foothills of the San Bernardino Mountains.

Over the last 68 years, Nestlé extracted an average of 62 million gallons per year from wells drilled into the upper watershed of Strawberry Creek. According to figures presented at the hearing, this is over 5% of the safe yield of the entire San Bernardino Basin, which supplies the cities of San Bernardino, Riverside, Redlands, and others. Even in the midst of a multi-year drought, in 2015, Nestlé extracted 36 million gallons.

Nestlé’s extraction of millions of gallons per year occurred even as residents and businesses were required to restrict their own water usage.

For this amount of water, the company paid only $524 each year. One speaker said this came out to $3.65 per acre-foot of water, which the company then sold for 100,000 times that amount.

36  million gallons extracted in 2015, in the midst of a multi-year drought, means that much water did not make it to the creek. This means all of the plants and animals that once lived in the creek are short that much water.

Loe made it clear that the “mountain springs” of Strawberry Creek are not artesian springs which leap out the ground. Rather, they are horizontal wells drilled over 500 feet deep, maximizing groundwater extraction in the creek’s upper watershed, before water even gets to the creek. The drill sites are so dry that no riparian vegetation appears in their vicinity.

Nestlé claims to only extract water that is in ‘excess’ of the Forest Service’s current and foreseeable needs.

Given the outsized importance of riparian habitats in contributing to local biodiversity and providing regional ecological connectivity,  Loe asked, can one say there is excess water when a creek is close to its lowest flows on record? Species that depend on riparian habitat are at low population levels, and others historically associated with the San Bernardino Mountains, have disappeared. Loe believes Nestlé’s extraction of groundwater was a contributing factor in the disappearance of Santa Ana speckled dace, a native fish species, from the area after 2003.

In a statement by the Center for Biological Diversity, the Story of Stuff, and Courage Campaign Institute, Eddie Kurtz wrote, “The U.S. Forest Service has been enabling [Nestlé] to destroy delicate ecosystems in the San Bernardino National Forest for 27 years, and it has to stop. Our government won’t stand up to them, so we’re taking matters into our own hands.”

The Bridge to Nowhere over the East Fork of the San Gabriel River, photos by Carrie Lincourt

Last week, a friend and I took a really great hike up the East Fork of the San Gabriel River to the Bridge to Nowhere. It’s an excellent local day hike (9.5 miles round trip) that I highly recommend, though it’s probably best done during cooler seasons – say between late September and early June.  « Read the rest of this entry »

What would Snow White say? Disney Ranch to culvert a small stream and cut down 158 oaks

June 4, 2012 § 5 Comments

Snow White’s animal pals are going to be missing some of their woodland at the new Disney campus:

“The Project would require the removal of 158 County Ordinance-protected oak trees, including 16 heritage oak trees, and encroachment upon an additional 82 oak trees, including 3 heritage oaks…” (EIR, V.F-72)

“The Project would permanently impact approximately 0.08 acre (1,181 linear feet) of ACOE/RWQCB jurisidictional area…The Project would permanently impact 0.63 acre of CDFG jurisdictional streambed and associated habitat…” (EIR, V.F-81) “ACOE/RWQCB jurisdictional area” is jargon for Water of the US/Water of the State-admittedly, more jargon.  In other words, blue line stream.  You may observe here that status as a Water of the US/Water of the State doesn’t ensure protection, despite many characterizations to that effect, when environmentalists battled to preserve the designation on the LA River.

Existing mapped floodplain area (Zone A at left) to be reduced through Development Area.

Also, while this is most likely the FEMA 100-year storm floodplain shown on this map, as creekfreaks already know, floodplains are an essential part of the stream system, reducing the space for it has negative consequences for stream health.

This, as the High Country News recently remembered the loss of the Arcadia Oak Woodlands, albeit for a different reason.  I am grateful that we’re not arguing about Placerita Creek.  But loss of tributaries and confining the main channel’s floodplain are worrisome.  I don’t have time to read and interpret the entire EIR just now, so just letting you know that this on the docket.  AND if you are in the Santa Clarita area, there’s a hearing tonight (June 4) about the project:

Based on this piece in the Whittier Daily News, Snow White’s pals will also have to hop around oil rigs on open space purchased with allocations from the County of LA’s Proposition A, which is a funding source designated for recreation, parks, and open space.

Thoughts on a One-Way Morro Bay Watershed Sign

May 9, 2012 § 7 Comments

I just returned from a very enjoyable vacation in San Luis Obispo, California. I stayed in downtown SLO and, a few times, bicycled out to the Los Osos Oaks State Natural Reserve, about ten miles away. As I was bicycling west on Los Osos Valley Road a cresting a ridgeline, in the midst of agricultural fields, I saw this sign along the highway:

It reads “MORRO BAY ESTUARY WATERSHED / KEEP IT CLEAN / ENTERING.”  « Read the rest of this entry »

Urgent action needed: identify City of LA creeks for protection under ordinance

March 7, 2012 § 5 Comments

Creek Freaks, I am posting this message on behalf of Shelley Luce, Executive Director, and Mark Abramson, their Senior Watershed Advisor.  They need your help by Friday March 16.  I have my own comment to add following their request:

Send us your Streams and Creeks!

Calling all Creek Freaks! The Santa Monica By Restoration Commission needs your help identifying and locating streams and creeks in the City of Los Angeles. The City is creating a stream protection ordinance designed to protect the few remaining healthy creeks within the City limits. They have requested a list of streams and creeks that should be protected. We are asking all our friends and creek enthusiasts to send us pictures and locations of creeks within the City so that we can ensure their protection. If you have a favorite creek spot that you feel warrants protection please send the location (preferably latitude and longitude, a picture, and any information that you might have about the stream or creek. The Santa Monica Bay Restoration Commission will then visit these sites and compile a list of streams and creeks that should be protected for the inclusion in the City of Los Angeles’ Stream Protection Ordinance.  Please send any information to  smbrc@waterboards.ca.gov using the subject line Protect this Stream. Your efforts will help protect these few remaining special places for generations to come. « Read the rest of this entry »

Hope takes the 3:10 to Yuma (and the lower Colorado River)

December 1, 2011 § 1 Comment

Speaking of the lower Colorado River, check out this wonderful video giving some historical context, issues and hope:

Click on image for link to video.

The rebound of bird species is particularly notable with this restoration project, where the prior, degraded, condition included filled channels, disconnected wetlands, and a lack of natural flooding resulting in the loss of habitat diversity and a thicket of non-native species.  Reflecting on some local arguments, I see that a combo of hand labor and big machines were used, dredging for floodplains and re-establishment of channels.  Restoring flooding with “industrial style” restoration with adaptive management techniques might not always be so bad after all…

For more info, here’s a slide show and an article in the journal Ecological Restoration.

Thanks to Fred Phillips, a Flagstaff-based landscape architect, who shared this link about his work with me when I went to visit the Friends of the Rio de Flag earlier this year.
