The ship canal project began in 1911 and was officially completed in 1934. Prior to construction of the Lake Washington Ship Canal, otherwise known as the Salmon Bay Waterway, water used to exit Lake Washington via the [[Black River (Duwamish River)|Black River]] which flowed from the south end of Lake Washington into the Duwamish River.

As early as 1854, there was discussion of building a navigable connection between Lake Washington and Puget Sound for the purpose of transporting logs, milled lumber, and fishing vessels. Thirteen years later, the [[United States Navy]] endorsed a canal project, which included a plan for building a naval shipyard on Lake Washington. In 1891 the [[U.S. Army Corps of Engineers]] started planning the project. Some preliminary work was begun in 1906, and work began in earnest five years later. The delays in canal planning and construction resulted in the U.S. Navy building the [[Puget Sound Naval Shipyard]] in [[Bremerton, Washington]], which is located across the Sound from Seattle.

===Early efforts ===

Lake Union was chosen to suggest the future canals merging the waters, and Lake Washington for [[George Washington]].<ref name=Thrush2007/><ref name=Crowley1999a/><ref name=Crowley1999b/>
[[File:Proposed Seattle canals.png|thumb|left|upright|Proposed canal routes included the [[Black River (Duwamish River)|Black River]], [[Eugene Semple|Semple's]] Canal across [[Beacon Hill, Seattle|Beacon Hill]], two possible routes from [[Lake Union]] to [[Elliott Bay]] via [[Lower Queen Anne, Seattle|Lower Queen Anne]] and [[Belltown, Seattle|Belltown]], the [[Montlake Cut]], and [[Salmon Bay]] to [[Smith Cove (Washington)|Smith Cove]] via [[Interbay, Seattle|Interbay]].]]
In 1860 local landowner Harvey L. Pike tried to dig a ditch by himself with pick and shovel at [[Montlake Cut|Montlake]] to transport logs between [[Portage Bay]] and [[Union Bay (Seattle)|Union Bay]], in the hopes of increasing the value of his property along the route.<ref name=Long2001/> Giving up on digging the first Portage Canal himself, in 1871 he joined [[Thomas Burke (Seattle)|Thomas Burke]] and [[Daniel Hunt Gilman|Daniel Gilman]] in incorporating the Lake Washington Canal Company, deeding his land to the company. Instead of finishing the canal, the company instead built a tramway to carry coal brought by barge across Lake Washington.<ref name=Long2001/> In 1883, [[David Denny]] and Burke hired a crew of Chinese laborers to complete the canal at Montlake, creating a {{Convert|16|ft|adj=on}} channel that included a lock, capable of floating logs down from Lake Washington to Lake Union.<ref name=Long2001/>

The Army Corp of Engineers investigated Puget Sound for military defense purposes and chose Lake Washington as the best location for a Naval base, due to the security of the waters, proximity to supplies of fresh water, coal and timber, and the less corrosive effect on wooden ship hulls of a [[fresh water]] port.<ref name=Ficken1986/><ref name=Alexander1884/> A report by Lieutenant Thomas H. Hardy of October 13, 1871, forwarded to Congress by Army General B. S. Alexander of the Board of Engineers of the Pacific Coast said the coal fields of [[Seattle Coal and Transportation Company]], two miles east of [[Lake Sammamish]], supplied 1,500 tons per month of [[steam ship]] grade coal, and potentially twice this amount.<ref name=Alexander1884/> The route directly across the narrowest part of Seattle, that is, [[Eugene Semple|Semple's]] Canal from [[Leschi, Seattle|Leschi]] straight across to present-day [[Harbor Island, Seattle|Harbor Island]], was rejected in this report because of the 200 to 300 foot height of the hills that would have to be cut through.<ref name=Alexander1884/> The route via the Black and [[Duwamish River]]s would be crooked and several miles in length, would let out into [[shoal]]s rather than deep water, and would have to be frequently dredged to remove sand brought by river flooding.<ref name=Alexander1884/> As to connecting Lake Union to [[Shilshole Bay]] — the route ultimately chosen — Gen. Alexandar had "serious objections", including the expense and the need for dredging a channel, and that the canal line let out in shoal water that was exposed to heavy seas, and would be less defensible in wartime, being "exposed to the cannonade of an enemy".<ref name=Alexander1884/> Alexander was less opposed to digging straight south from [[Salmon Bay]] through [[Interbay, Seattle|Interbay]] to [[Smith Cove (Washington)|Smith Cove]], but would still terminate in shoals and be just as costly as his preferred route from Lake Union through Mercer's Farm into Elliott Bay, while being less defensible.<ref name=Ficken1986/><ref name=Alexander1884/> The estimated cost for the project was $4.7 million.<ref name=Ficken1986/>

In the [[Rivers and Harbors Act]] of 1902, [[United States Congress|Congress]] directed the Secretary of War to appoint a committee of three officers to study the feasibility of a canal and lock system to connect Puget Sound to Lake Washington. Lieutenant Colonel William H. Heuer, Captain [[William Campbell Langfitt|William C. Langfitt]] and Lieutenant Robert P. Johnson met August, 1902 in Seattle and conducted a survey of possible routes.<ref name=EngineersReport1903/> They examined the route of the Lake Washington Waterway Company, via Shilshole Bay, as well as a route from Lake Union to [[Smith Cove (Washington)|Smith Cove]], the Montlake coal tramway, and Thomas Mercer's farm. In November 1902, a public meeting was called in the Chamber of Commerce hall, but was quickly adjourned because no one came to speak.<ref name=EngineersReport1903/>

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 (developer)|James A. Moore]], known today for the [[Moore Theater]] and [[Moore Haven, Florida]], proposed a canal that could accommodate small ships, with two wooden locks connecting [[Salmon Bay]] to [[Shilshole Bay]].<ref name=Woog2008/>{{rp|23–25}} Moore secured Congressional approval for his project, granting him rights to build.<ref name=Ficken1986/> In April of the same year, [[Hiram M.

The Lake Washington Ship Canal, which runs through the city of Seattle, Washington, connects the fresh water body of Lake Washington with the salt water inland sea of Puget Sound. The Hiram M. Chittenden Locks accommodate the approximately 20-foot difference in water level between Lake Washington and the Sound. The Canal runs east/west, and connects Union Bay, Lake Union, the Montlake Cut, Portage Bay, the Fremont Cut, Salmon Bay, and Shilshole Bay, with the Sound, which empties into the Pacific Ocean.

The ship canal project began in 1911 and was officially completed in 1934. Prior to construction of the Lake Washington Ship Canal, otherwise known as the Salmon Bay Waterway, water used to exit Lake Washington via the Black River which flowed from the south end of Lake Washington into the Duwamish River.

As early as 1854, there was discussion of building a navigable connection between Lake Washington and Puget Sound for the purpose of transporting logs, milled lumber, and fishing vessels. Thirteen years later, the United States Navy endorsed a canal project, which included a plan for building a naval shipyard on Lake Washington. In 1891 the US Army Corps of Engineers started planning the project. Some preliminary work was begun in 1906, and work began in earnest five years later. The delays in canal planning and construction resulted in the U.S. Navy building the Puget Sound Naval Shipyard in Bremerton, Washington, which is located across the Sound from Seattle.

Early efforts

For centuries, people had been dragging boats between the lakes, giving names like "carry a canoe" sxWátSadweehL to the crossing points.[2] In 1854 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.[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. Lake Union was chosen to suggest the future canals merging the waters, and Lake Washington for George Washington.[2][4][5]

Proposed canal routes included the Black River, Semple's Canal across Beacon Hill, two possible routes from Lake Union to Elliott Bay via Lower Queen Anne and Belltown, the Montlake Cut, and Salmon Bay to Smith Cove via Interbay.

In 1860 local landowner Harvey L. Pike tried to dig a ditch by himself with pick and shovel at Montlake to transport logs between Portage Bay and Union Bay, in the hopes of increasing the value of his property along the route.[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. Instead of finishing the canal, the company instead built a tramway to carry coal brought by barge across Lake Washington.[6] In 1883, David Denny and Burke hired a crew of Chinese laborers to complete the canal at Montlake, creating a 16-foot (4.9 m) channel that included a lock, capable of floating logs down from Lake Washington to Lake Union.[6]

The Army Corp of Engineers investigated Puget Sound for military defense purposes and chose Lake Washington as the best location for a Naval base, due to the security of the waters, proximity to supplies of fresh water, coal and timber, and the less corrosive effect on wooden ship hulls of a fresh water port.[3][7] A report by Lieutenant Thomas H. Hardy of October 13, 1871, forwarded to Congress by Army General B. S. Alexander of the Board of Engineers of the Pacific Coast said the coal fields of Seattle Coal and Transportation Company, two miles east of Lake Sammamish, supplied 1,500 tons per month of steam ship grade coal, and potentially twice this amount.[7] The route directly across the narrowest part of Seattle, that is, Semple's Canal from Leschi straight across to present-day Harbor Island, was rejected in this report because of the 200 to 300 foot height of the hills that would have to be cut through.[7] The route via the Black and Duwamish Rivers would be crooked and several miles in length, would let out into shoals rather than deep water, and would have to be frequently dredged to remove sand brought by river flooding.[7] As to connecting Lake Union to Shilshole Bay — the route ultimately chosen — Gen. Alexandar had "serious objections", including the expense and the need for dredging a channel, and that the canal line let out in shoal water that was exposed to heavy seas, and would be less defensible in wartime, being "exposed to the cannonade of an enemy".[7] Alexander was less opposed to digging straight south from Salmon Bay through Interbay to Smith Cove, but would still terminate in shoals and be just as costly as his preferred route from Lake Union through Mercer's Farm into Elliott Bay, while being less defensible.[3][7] The estimated cost for the project was $4.7 million.[3]

In the Rivers and Harbors Act of 1902, Congress directed the Secretary of War to appoint a committee of three officers to study the feasibility of a canal and lock system to connect Puget Sound to Lake Washington. Lieutenant Colonel William H. Heuer, Captain William C. Langfitt and Lieutenant Robert P. Johnson met August, 1902 in Seattle and conducted a survey of possible routes.[8] They examined the route of the Lake Washington Waterway Company, via Shilshole Bay, as well as a route from Lake Union to Smith Cove, the Montlake coal tramway, and Thomas Mercer's farm. In November 1902, a public meeting was called in the Chamber of Commerce hall, but was quickly adjourned because no one came to speak.[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 Theater and Moore Haven, Florida, proposed a canal that could accommodate small ships, with two wooden locks connecting Salmon Bay to Shilshole Bay.[9]: 23–25  Moore secured Congressional approval for his project, granting him rights to build.[3] In April of the same year, Hiram M. Chittenden came to Seattle as the new Army District Engineer.[9]: 23–25  Chittenden favored the same route to Shilshole Bay as Moore, but found the plan too modest, and potentially unsafe.[9]: 26 [3] Chittenden said Moore's hope-for budget of $500,000 was insufficient, and the locks should be built to accommodate larger vessels, and that the wooden locks would eventually deteriorate and collapse, draining Lake Washington into Puget Sound.[9]: 26 

Instead, Chittenden proposed a double concrete lock with steel gates, allowing small craft to pass with less waste.[9]: 27  A single set of locks on the western end of Salmon Bay would be used in place of the small wooden lock near Fremont Avenue, which would lower Lake Washington to the same level as Lake Union.[9]: 27  Having a single lock between Puget Sound and the freshwater lakes would reduce the risk of flooding and reduce overall cost of the project.[9]: 27  Before he could move forward, Chittenden had to sway local leaders away from supporting Moore's project.[3] After enthusiasm for his canal eroded and funding dried up, Moore transferred his rights to a public-private entity, the Lake Washington Canal Association, in 1907.[9]: 29 [3] Though Chittenden hoped to cap his career with the construction of the Locks, ill health forced him to retire in 1909, though he continued lobbying Congress for the project, and served as a consulting engineer and as a Seattle port commissioner until his death in October 1917.[9]: 31
