GREEN LAKE
I’ve been wanting to write about Seattle’s Green Lake, which is an addition to round out the post these small Seattle lake stories, and supplement the coverage of the larger lakes Union and Washington. Green Lake has a special place for me, having lived close to it our entire time in Seattle, it’s been a place for fun, recreation, and even protest. This really cool cross-time image from Then & Again shows the juxtaposition of the current with the old, and Green Lake spanning this , here with “…the majestic USS Macon gliding above Seattle’s Green Lake on August 22, 1934. The airship was traveling to its new station near San Francisco but took a leisurely route with time for a number of photo ops along the way.”
The history of the lake goes back to similar era to the smaller Bitter and Haller Lakes and the larger Lake Union and Washington, as mentioned on the Seattle Parks website: “Geologists say the Vashon Glacial Ice Sheet, which also formed Puget Sound and other area lakes, formed Green Lake 50,000 years ago. Dredgings of Green Lake have produced volcanic ash from an eruption of Glacier Peak that occurred about 6,700 years ago.” The original lake was lowered 7-8 feet as park of early 20th Century Park improvements, and this 2014 article from Seattle Greenlaker ‘Olmsted and the Origin of Green Lake Park‘ offers a good introduction to the modern incarnation of the park and this process. In that post, it links to this great map from 1907 from the National Association of Olmsted Parks, which shows the development of Green Lake Boulevard and the areas near the lake as part of this process, and the first evolution of Green Lake as part of the overall Park System.
If you were, like me, temporarily disoriented for a bit, it helps to rotate this drawing so north is up, and the more familiar shapes and lobes of the lake become clearer. I’ve also highlighted the old shoreline (dashed line) and the new shoreline (solid line w/ blue fill), so it’s clearer where the drawdown left space for the trails and more usable open spaces, with amenities like Boat Houses and beaches. The map also has information on the inlets and outlets, which I’ve highlighted below in a bit more detail for reference.
If you remember back a bit to my post of the exploration of Licton Springs, the sketch above is instructive, as this inlet #1 shows an inlet with a specific reference: the “Brook inlet box culvert 2’x6′ from Licton Min. Sprg.”, showing the subsurface connection to the spring that had been filled in previously but was still flowing from the north. A Bathhouse is shown, which does not currently exist, but there is a swimming beach access which is still in place today, along with the splash play and some open spaces.
There is another pair of inlets #2 a bit further west, near Corliss Avenue, with a label “Inlet box 1 1/2′ x 2′” and near there is one with a note “Old Inlet 18″x18” wood box” which has a note “very little flow now – some sewerage seems to enter it now.”
The final inlet #3, is to the west, showing a connection to an “Inlet-brook, 6′ wide, 3″ deep” that comes from the northwest, running under the streetcar track in a culvert before coming into the lake.
On the opposite side of the Lake, heading southeast, there is the Outlet, which is marked #4, near 4th Avenue (a few blocks from the proposed boulevard which would become current day Ravenna Boulevard), which was the natural drainage of Green Lake into Ravenna Creek. The reconfiguration of this zone and the shift of the shoreline created a larger area that now has sports fields, as well as a boat house and what is a popular beach access spot today. This is also adjacent to the larger commercial zone which is the hub of activity adjacent to the lake.
These flows in and out correlates somewhat with the 1850s maps, but does closely align with the the USGS Topo Map from 1894 (see below) of Green Lake that identify three inlets from the north and the Ravenna outlet heading southeast – which does line up with the hydrology shown on these 1907 drawings.
The formal plan as presented to the Seattle Parks Commission in 1910 mirrors much of the modern day condition, with the lowered water levels providing for perimeter trails, new plantings, a new island, some amenities such as beaches and boathouses, and the boulevard that rings the park (the western half of which was transformed with the routing of Aurora Boulevard (Highway 99).

I posted previously about the fun bathymetry maps, which included Green Lake. Another map I like is this one ‘Showing Depth Contours of Green Lake’ via the Seattle Municipal Archives Flickr page, which was done in 1938 as part of the Sanitary Survey by the WPA and featured in the “Report on Green Lake Algae Control”, which highlights perennial water quality issue . It reinforced that the lake is relatively shallow, with maximum depths no greater than 25′ feet on the western edge. It also identifies some of the hydrology, including overflows, intake from the City resevoir, and to the west, a “permanent inlet from deep springs” which is a fascinating addition both due to it’s mystery and also it’s location, which is not shown on later maps but does appear in the 1950s map.
The history of the lake beyond that Olmsted plan has many facets and this Chronology is helpful to see the evolution. There many tales (and History Link is a great resource here) that connect with Seattle history, such as in 1869, when David Denny “…kills what is likely the last elk in Seattle, near Green Lake. The elk weighs 630 pounds.”, or 1893 when a cold spell froze the lake completely over. including of Hydroplane boat races in the 1930s, as well as a cleanup and redesign in 1936. Lots of history and evolution I won’t get into here, as it’d take days, but my favorite lost part of the Green Lake history, which I only discovered by accident after visiting the park many times, is the Aqua Theater, built in 1950 on the south edge of the lake as a 5,500 seat performance venue, built in a little more than two months coinciding with the first of what is now an annual Sea Fair.
The venue hosted a range of events included the annual Aqua Follies, which included ” Water ballets, diving exhibitions and clown acts took place in the pool and on the stage behind. Many of the Aqua Follies mermaids were recruited in Minneapolis before June 1, and began practicing before Seattle area college students finished their school term.” There were some notable music shows including 1969, which featured Led Zepplin and The Grateful Dead, which was one of the final shows at the venue before it was shut down.
The lake as a locus for recreation has stayed consistent over the years, with lots of walkers and joggers circling the 3 mile loop, along with water access via boat rentals, rowing, and use of adjacent open spaces sports fields, and even a Par 3 golf course. Water quality issues are a perpeutual issue, but it doesn’t stop it from being the busiest park in the state of Washington, with over a million visitors a year.

I’m curious to know if you know of a covered stream that flows south roughly under 26th St. in Ballard down to Salmon Bay. When you walk along the streets there, every time you pass a man-hole cover you can hear rushing water even on dry days. Someone told me that it is actually a stream but while some of the maps you show of the Green lake area indicate that there might be a drainage to the west that might fit this bill, many maps don’t show anything.
Is there any sort of old legend about green lake like buried treasure lol
