The Chehalis River is located in the southwest corner of British Columbia, Canada near the city of Chilliwack. It flows south-eastward out of the Douglas Ranges of the Coast Mountains, draining into the Harrison River.
Harrison Hot Springs is a village located at the southern end of Harrison Lake in the Fraser Valley of British Columbia. It is a member of the Fraser Valley Regional District; its immediate neighbour is the District of Kent, which includes the town of Agassiz.

The Lillooet River is a major river of the southern Coast Mountains of British Columbia. It begins at Silt Lake, on the southern edge of the Lillooet Crown Icecap about 80 kilometres northwest of Pemberton and about 85 kilometres northwest of Whistler. Its upper valley is about 95 kilometres in length, entering Lillooet Lake about 15 km downstream from Pemberton on the eastern outskirts of the Mount Currie reserve of the Lil'wat branch of the St'at'imc people. From Pemberton Meadows, about 40 km upstream from Pemberton, to Lillooet Lake, the flat bottomlands of the river form the Pemberton Valley farming region.
Harrison Lake is the largest lake in the southern Coast Mountains of Canada, being about 250 square kilometres (95 mi²) in area. It is about 60 km (37 mi) in length and at its widest almost 9 km (5.6 mi) across. Its southern end, at the resort community of Harrison Hot Springs, is c. 95 km east of downtown Vancouver. East of the lake are the Lillooet Ranges while to the west are the Douglas Ranges. The lake is the last of a series of large north-south glacial valleys tributary to the Fraser along its north bank east of Vancouver, British Columbia. The others to the west are the Chehalis, Stave, Alouette, Pitt, and Coquitlam Rivers.
Pitt Lake is the second-largest lake in the Lower Mainland of British Columbia. About 53.5 km2 (20.7 sq mi) in area, it is about 25 km (16 mi) long and about 4.5 km (2.8 mi) wide at its widest. It is one of the world's relatively few tidal lakes, and among the largest. In Pitt Lake, there is on average a three-foot tide range; thus Pitt Lake is separated from sea level and tidal waters during most hours of each day during the 15 foot tide cycle of the Pitt River and Strait of Georgia estuary immediately downstream. The lake's southern tip is 20 km (12 mi) upstream from The Pitt River confluence with the Fraser River and is 40 km (25 mi) east of Downtown Vancouver.
The Pitt River in British Columbia, Canada is a large tributary of the Fraser River, entering it a few miles upstream from New Westminster and about 25 km ESE of Downtown Vancouver. The river, which begins in the Garibaldi Ranges of the Coast Mountains, is in two sections above and below Pitt Lake and flows on a generally southernly course. Pitt Lake and the lower Pitt River are tidal in nature as the Fraser's mouth is only a few miles downstream from their confluence.
The Harrison River is a short but large tributary of the Fraser River, entering it near the community of Chehalis, British Columbia, Canada. The Harrison drains Harrison Lake and is the de facto continuation of the Lillooet River, which feeds the lake.
The Douglas Ranges are a subrange of the Pacific Ranges of the Coast Mountains of the Canadian province of British Columbia, about 70 km (43 mi) east of downtown Vancouver, north of the Fraser River and between the valleys of Stave and Harrison Lakes. They are approximately 4,900 km2 (1,900 sq mi) in area. Their highest peak is Mount Robertson 2,252 m (7,388 ft), at the northwest limit of the range.
Chehalis is a small forestry, agricultural and First Nations community in the Lower Mainland of British Columbia located on Highway 7 on the west bank of the Harrison River between the town of Mission and the resort community of Harrison Hot Springs.
The District of Kent is a district municipality located 116 kilometres (72 mi) east of Vancouver, British Columbia. Part of the Fraser Valley Regional District, Kent consists of several communities, the largest and most well-known being Agassiz—the only town in the municipality—Harrison Mills, Kilby, Mount Woodside, Kent Prairie, Sea Bird Island and Ruby Creek. Included within the municipality's boundaries are several separately-governed Indian reserves, including the Seabird Island First Nation's reserves on and around the island of the same name.
Harrison Mills, formerly Carnarvon and also Harrison River, is an agricultural farming and tourism-based community in the District of Kent west of Agassiz, British Columbia. The community is a part of the Fraser Valley Regional District. Harrison Mills is home to the British Columbia Heritage Kilby Museum and Campground.

The Nahatlatch River is a tributary of the Fraser River in the Canadian province of British Columbia. It originates in the Lillooet Ranges of the Coast Mountains and empties into the Fraser River in the Fraser Canyon, north of Boston Bar.
Chehalis Lake is a lake on the Chehalis River in the Lower Mainland of southwestern British Columbia, Canada. The lake and the river share the name with the community of Chehalis, British Columbia, which is the home of the Sts'Ailes people, a Halqemeylem-speaking Coast Salish group. Their name Sts'Ailes is said to mean "beating heart"; the similarly named Chehalis, Washington and Chehalis River in that area have a different meaning in the Chehalis language - "sand".
Lake Errock is an unincorporated community in the Fraser Valley region of southwestern British Columbia. Housing exists primarily on the northwestern shore of the same named lake, which lies southwest of Harrison Bay. The locality, on BC Highway 7, is by road about 23 kilometres (14 mi) west of Agassiz, 95 kilometres (59 mi) east of Vancouver, and 28 kilometres (17 mi) east of Mission.
The Sq'éwlets First Nation (Scowlitz) is the band government of Skaulits subgroup of the Stó:lō people located on Harrison Bay in the Upper Fraser Valley region between Chehalis (E) and Lake Errock, British Columbia, Canada (W). They are a member government of the Stó:lō Tribal Council.
Harrison Hill (622m) is a small mountain located at the confluence of the Harrison and Fraser Rivers in the Lower Mainland region of British Columbia, Canada. Harrison Knob (~225m) is a prominent shoulder to the east of the main peak of Harrison Hill. Harrison Hill and Harrison Knob are on the north side of the Fraser opposite Chilliwack, Harrison Knob overlooks the confluence directly, Harrison Hill itself separates the Fraser downstream from that confluence and overlooks on its north Harrison Bay, a large, shallow lake-like sidewater of the Harrison River, while at its western foot is the community of Lake Errock. At its eastern foot, just below Harrison Knob, had been the formerly large sawmill town of Harrison Mills, which spanned both sides of the Harrison and was served by the mainline of the Canadian Pacific Railway, which runs along the north side of the mountain's base. The Indian Reserves of the Scowlitz First Nation are at the western end of Harrison Bay and at its outlet at its eastern end, while the reserve of the Chehalis First Nation is along its north shore, and Kilby is on its east shore.
Harrison Bay is a lake-like expansion of the Harrison River, located west of its main course adjacent to the communities of Chehalis and Harrison Mills in the Canadian province of British Columbia. Extremely shallow, the bay outlets to the Fraser at Harrison Mills, where in pre-gold rush times there had been a "riffle", which was dredged to enable easier steamer traffic to Harrison Lake and Port Douglas. The bay has been used as a log sort but is primarily recreational in use today, with the Scowlitz Indian Band running a beach and campground at its western end, on Squawkum Creek Indian Reserve No. 3, which is at the southwest corner of Harrison Bay. Between it and the Fraser lies Harrison Hill, known in Upriver Halkomelem as Qithyll, which is an ancient burial ground currently under investigation by the First Nation in a joint effort with Simon Fraser University's archaeology department.. Adjacent to Kilby Provincial Park and the site of Harrison Mills are Williams Indian Reserve No. 2 and Scowlitz Indian Reserve No. 1
