Lake Washington is a wide spot in the St. John's river created by a weir at the north end. In 1970 the fish were numerous enough for the state to permit commercial fishing in the lake. Before that, the lake was much bigger; the islands and peninsulas much smaller. Neomysis is a native species that has been present in Lake Washington for many decades, but has been scarce since 1968. Now we can see how changes in the amount of phosphorus, mainly from sewage outfalls into the lake, affected the species composition of the lake. They do feed on Daphnia, but the sockeye fry appear in the lake about March or April, a month or two before Daphnia becomes abundant. Salmon Bay is part of the fresh water system of the Lake Washington ship canal. Their capacity is exceeded on this continent only by the Panama Canal locks. [3] In April of the same year, Hiram M. Chittenden came to Seattle as the new Army District Engineer. Prior to construction of the canal, the only significant inflow was from the Sammamish River in the north. [8], In 1906, as local debate over the location of the canals continued, and funding from Washington, D.C. was delayed, Seattle developer James A. Moore, known today for the Moore Theatre and Moore Haven, Florida, proposed a canal that could accommodate small ships, with two wooden locks connecting Salmon Bay to Shilshole Bay. Vessel owners should closely monitor lake elevations and adjust mooring lines as necessary. Lake Washington's two major influent streams are the Cedar River at the southern end, which contributes about 57 percent of the annual hydraulic load and 25 percent of the phosphorus load,. For questions about Lake Washington, please contact Debra Bouchard, Water Quality Planner or Curtis DeGasperi, Lead Hydrologist, King County Science and Technical Support Section. The commercial hunt subsided in the 1940s, but sea lions still had adversaries to contend with—commercial and sport fishermen were allow… The Ship Canal is the only discharge from lakes Sammamish and Washington via the locks and dam at the western end. The Hiram M. Chittenden Locks, more popularly known as the "Ballard Locks," is worth visiting for a number of reasons.

In the late 1970s, Paul Murtaugh of the University of Washington studied the gut contents of Neomysis and concluded that it is an especially potent predator on Daphnia, capable of strongly influencing Daphnia abundances. Largemouth and smallmouth bass are potential predators on sockeye, and one theory is that an increase in the number of boat docks has resulted in an increase in habitat for the bass. [6] Giving up on digging the first Portage Canal himself, in 1871 he joined Thomas Burke and Daniel Gilman in incorporating the Lake Washington Canal Company, deeding his land to the company. [9]:27 Before he could move forward, Chittenden had to sway local leaders away from supporting Moore's project. While California sea lions are found from Baja California, Mexico, to Alaska, they had largely been driven out of Puget Sound by the 1930s, pursued by commercial hunters seeking oil, hides, meat for the pet food market, and male genitals to be used as aphrodisiacs in Chinese medicine. In 1891 the US Army Corps of Engineers started planning the project. The uses of Ecology: Lake Washington and Beyond. Contrary to common notion, UW research has not shown northern squawfish to be preying substantially on sockeye in Lake Washington, but cutthroat and rainbow trout have actually been implicated as being predators on the sockeye. [3] Mercer gave the lakes the names they are presently called, over the original Lushootseed names used by the Duwamish, tenas Chuck or XáXu7cHoo ("small great-amount-of-water") for Lake Union and hyas Chuck or Xacuabš ("great-amount-of-water") for Lake Washington. The late Dr. W.T. [9]:26, Instead, Chittenden proposed a double concrete lock with steel gates, allowing small craft to pass with less waste. As of early August, 17,000 sockeye had returned from the … Major Hiram M. Chittenden (1858-1917) of the Corps finalized a plan to build a canal between Shilshole Bay, on Puget Sound, and Lake Washington, passing through Salmon Bay to Lake Union, then on to Lake Washington. Wouldn't recommend swimming or water skiing as it does have a population of alligators, like most Florida lakes. (Aerial photo from U.S. Army Corps of Engineers). This finding had major implications for industry, and great political discussion resulted. Just as Dr. Edmondson had predicted, completing these major facilities brought dramatic results. Lake Washington is the largest of the three major lakes in King County, and the second largest natural lake in the State of Washington. [2] In 1854 Seattle pioneer Thomas Mercer proposed canals connecting Lake Union and Lake Washington to Puget Sound in a speech at the first Independence Day celebration of the Seattle area's first permanent white settlement, shortly after its founding. Government agencies have been working to sustain salmon habitat and to control flood damage in the area, and the smelt may have benefited from these habitat improvements. A bill proposed by Sen. Doug Ericksen, R-Ferndale, would breach the Ballard Locks first, before the Snake River dams near Tri-Cities. University of Washington Press. This photo, taken around 1911, shows the canal in … The Westside lawmaker said Seattle has … 1991. The canal runs east–west and connects Union Bay, the Montlake Cut, Portage Bay, Lake Union, the Fremont Cut, Salmon Bay, and Shilshole Bay, which is part of the sound. Edmondson, former professor of zoology at the University of Washington, (external link) studied the biology and chemistry of Lake Washington for many decades. ), Seattle's waterways in the 1990s, showing the effect of the canal (and of other projects, such as the undergrounding of many streams and the re-routing, dredging, and industrialization of the, Salmon Bay Harbor Map, Seattle Public Library, SEAMAP G4284.S4 P53 1892.S6, U.S. National Register of Historic Places, "Seattle residents celebrate July 4, 1854, and adopt names for Lake Union and Lake Washington", "Harvey Pike starts to dig a canal connecting Seattle's Union and Portage bays in 1860", "Report to accompany bills S. 1202, 2135", History of the National Register of Historic Places, https://en.wikipedia.org/w/index.php?title=Lake_Washington_Ship_Canal&oldid=990669550, National Register of Historic Places in Seattle, Canals on the National Register of Historic Places in Washington (state), 1934 establishments in Washington (state), Articles using NRISref without a reference number, Short description is different from Wikidata, Pages using multiple image with manual scaled images, Creative Commons Attribution-ShareAlike License, Landowner Harvey L.
