[13] During the Big Bend Gold Rush of 1865, Governor Frederick Seymour commissioned Walter Moberly to identify the best route for a wagon road or railway from Shuswap Lake to the Columbia River.

[18] The rebuild included a few hotels, stores, dance halls, livery barns,[19] and a NWMP barracks and jail.

[23] The unwillingness of Mr. Bryne to sell land for a railyard east of the narrows compelled CP to build on the west side.

[25] In 1887, he built a two-storey extension which housed a store on the ground floor,[26] was appointed postmaster,[27] and erected a barn.

[25] At that time, a narrow and swampy in places wagon road was built to supersede the trail southward along the western side of Mara Lake, which connected Sicamous and Enderby.

[39] In 1898, a fire ignited by a dropped oil lamp in the dining room of the hotel[40] spread to the station, destroying both properties.

[53] Great Depression relief camp workers built the Canoe–Sicamous road,[54] which would reduce the travel distance between Salmon Arm and Sicamous by 23 kilometres (14 mi).

[56] By this time, Robert (Bob) H. Congreve supplied boats and cars at his service station on the shore below the Bellevue Hotel.

[58] In 1956, the primary access point for rail passengers into the Okanagan switched to Salmon Arm, which offered a superior bus connection.

[60] In August 1871, as a symbolic gesture that the railway would one day become a reality, Ed Mohun, government engineer, drove the first stake on the CP route in BC at Sicamous.

[61] In September 1885, the eastward advance of the CP rail head from Port Moody passed through Sicamous, reaching a point about 55 kilometres (34 mi) west of Revelstoke by month end.

[65] To temporarily disperse the mosquito infestation in the earlier decades, a yard locomotive belching smoke and steam was run through the station prior to passenger train arrivals.

[66] The 1885 timber pile trestle rail bridge had a wooden drawbridge for river traffic, which was replaced in 1898 by a manually turned swing span.

[70] In 1892, the locomotive tender and four cars of a westbound passenger train derailed 8 kilometres (5 mi) west, causing extensive damage.

[74] In 1900, a yard worker was crushed to death between the buffers of two freight cars, which unexpectedly rolled during a coupling exercise.

[76] In 1908, a fireman manoeuvring along a work train 3 kilometres (2 mi) east, who fell between the cars, sustained a fatal severing of an arm and leg.

[92] In 1959, the westbound royal train carrying the Queen and Prince Philip made a 20-minute stop, which comprised a similar program to the previous visit.

[96] In 2004, a man was sentenced to six years jail for causing bodily harm, having lain on the tracks with his son 13 kilometres (8 mi) east and being struck by a train.

[121] Although opposed by the clergy and unions, the introduction of Sunday service on the branch line in 1911 proved popular with the public.

[165] The Annis venture appears to have closed by this time, and a conversion to a sawmill took place from 1907[166] to 1909, when it emerged as Shields' Sovereign Mill.

[170] That year, Rolf Wallgren Bruhn owned the first house on CPR hill,[82] where his lumber head office was also located.

Initially, Carney maintained a branch office at Sicamous, but in 1966, he established a big yard for post-peeling activities.

[198] In 1958, the Eagle Valley News was founded,[199] and the Lazy Daze Marina Motel & Campground was established (later known as Bluewater Houseboat).

[203] Opened in 1963 were the United church building[204] and the Husky service station/restaurant, which was designed as a rest stop for long haul trucking.

[207] In 1971, an explosion destroyed the Sicamous Marina, an adjacent home, boats, motors, snowmobiles, and other sporting goods.

[208] In 1972, about 25 families fled to higher ground when up to 1 metre (3 ft) of water surged through the downtown area from the rain-swollen Shuswap and Mara lakes.

[220] In 1910, the one-room Sicamous school, which opened on leased land near the creek up on CPR hill, lacked any road access.

[224] During the summer break, lumber donated by the Bruhn mill, and from demolishing the closed Sicamous school, was used to build an extension at Eagle Valley to create a second classroom.

[242] Growth has depended upon the resort industry and the state of the energy sector in Alberta (30 per cent of occupancy being seasonal).

[263] In 2022, the scope of the District of Sicamous boundary expansion study was reduced when Swansea Point and Mara Hills were excluded.
