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.-State Engineer William Hammond Hall Papers, Misc. Working Papers, General Irrigation Info, Reports- LA County (Schuyler)
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!

Enjoy this new video from a couple of intrepid folks who recently attempted to kayak the L.A. River… and didn’t get very far… but nonetheless made a fun video showing their experience. They put in near Griffith Park’s Bette Davis Picnic Area – at the edge of the city of Glendale’s Glendale Narrows River Walk and only got to the adjacent Griffith Park Ferraro soccer fields.
There are plenty of places to put in and kayak the L.A. River safely and enjoyably – see my 2008 account of my first kayak trip there: day1, day2 and day3. The Burbank and Glendale stretches do involve plenty of portaging (walking.) There are also various organized kayaking tours these days. One warning: the L.A. River can get very dangerous very quickly during rainy weather, just watch No Way Out. The best time to kayak is when it’s not raining.

A couple weeks ago, I got a chance to bicycle a few miles of the Bronx River. It’s not unlike the Los Angeles River: a very urban, relatively industrialized freshwater river, in the process of making a dramatic comeback – with new parks and bike paths along its degraded banks. « Read the rest of this entry »

As the heat of summer slowly (hopefully) begins to wind down, so too has the second season of the pioneering L.A. River kayak and canoe excursions. The final group dropped into the River this past Sunday, an undoubtedly leisurely paddle between willows and sycamores, shopping carts and plastic bags. The 2012 installment hosted approximately 2,000 participants, an impressive increase from 2011, when the count for the pilot program was 260. The number of outfits operating on the River has also doubled and now includes Paddle the L.A. River (organized by L.A. Conservation Corps, MRCA, The River Project, FoLAR and Urban Semillas) and L.A. River Expeditions (organized by George Wolfe and the San Joaquin River Stewardship Program). I had the pleasure of paddling with both groups as a guest educator (thanks to Melanie Winter and George Wolfe for getting me out there!), a journey every Angeleno within reach of a buoyant non-motorized vessel should be able to experience at least once. « Read the rest of this entry »

Damon Nagami posted the video above at NRDC Switchboard. It’s an excellent, enthusiastic video review of just how fun the latest round of L.A. River kayaking tours are. It’s been great to see lots of photos and positive reviews on Facebook (some of which we’ve shared at the L.A. Creek Freak Facebook group page.) Angelenos are enjoying their river. « Read the rest of this entry »

So… no posts for a month, then two today… oh well. On my way bicycling back from this morning’s groundbreaking, I stopped to do a river sketch.
It’s in Elysian Valley, looking upstream toward the 2 Freeway Bridge. Note that I typically do a lot of vertical hatching, but when there’s water, the horizontal hatching is called for. More of my river drawings in my book, at my art show (up through August 15th 2012) and at my art blog.
I wasn’t the only person out doing L.A. River art today. « Read the rest of this entry »

Done with our touring of the Colorado River (1, 2, 3) and speed-reading about its issues, my 2nd year graduate landscape architecture design studio dove into planning and design solutions for the river. In the analysis phase, over and over, it was observed that the river ecosystem needed to regain its flooding and sediment dynamics. And over and over, it was observed that the political, human dimension would almost certainly never allow that to happen -regardless of the ecological desert created at the river’s mouth, and regardless of the obvious and dire future of the watershed due to climate change, population growth, and accumulating pollutants (including radioactive spoils behind reservoirs ya’ll!)
Clearly designing for what humans want usually comes at an environmental cost. The ecosystem loses! Even when it’s billed as sustainable, it’s more likely the design is about incrementally less harm to the ecosystem. So in this studio, designers were challenged with having the Colorado River as their Client. How do you work to meet human needs within that mandate? It becomes a much different conversation. Since many students don’t wish to explore “visionary” projects (visionary of course being the polite synonym for politically impossible, er, unrealistic), the studio was structured so that students could also provide concepts that inch us toward’s the River’s restored state, accommodating more of contemporary human uses while weaning us from an unhealthy allocation system. This combination of visionary plotting (mwaahaha) and phased steps towards rehabilitation put together make for a nice master plan.
You can read more about the studio and download most of the studio’s presentations at When the River is Client: Design Explorations of the Lower Colorado River. I hope you will! There’s some great ideas the students came up with.

I had the pleasure of meeting up with the Big Parade today as they walked along the Los Angeles River. If you’re unfamiliar with this event, it’s a walk that meanders through Los Angeles stairways, neighborhoods, etc – see their website. Part of their two-day this weekend included a stretch of the Glendale Narrows, so my friend, who’s the walking-force behind the parade, Dan Koeppel invited me to talk with the group.
I gave a very brief intro after meeting up with the group at Confluence Plaza, then we walked over the soon-to-be-demolished-and-freewayified Riverside-Figueroa Bridge to their lunch stop at Steelhead Park. I spoke about the past, present and future of the L.A. River. « Read the rest of this entry »

It seems as though there’s almost always a creek on golf courses in Los Angeles – be it natural, concrete or underground. And having proposed daylighting and restoration projects at a number of our local golf courses, I was happy to see this article, A Stream Runs Through It, published in the Golf Course Industry online magazine, supporting the idea. I have found that golf courses and streams can coexist, but too often golf courses alter the stream, pushing it over the edge of the property, constraining it in ways that destabilize it, removing habitat, etc. The management problems are often quite predictable. The opportunity exists to design a golf course with an understanding of stream habitat and function, leading to a richer golf experience, fewer maintenance issues, and habitat for that remaining 5-10% of LA’s waterways. Streams can separate greens, but when they traverse greens, they can become part of the play in interesting ways.
A couple of golf course/restoration locations I’ve referred to in Creek Freak posts include Devil’s Dip (I promise a post on just the golf course and restoration potential there in the near future but here’s a slide from Creek Freak’s recommendations to Mark Ridley-Thomas about it.) and South Pasadena Golf Course.
