Dewdney, originally named Johnson's Landing from 1884–1892, is an unincorporated community in the Central Fraser Valley of British Columbia, Canada, about 15 km east of the city of Mission. It was incorporated as a district municipality on April 17, 1892, including adjoining areas of Hatzic and Hatzic Island but the anticipated real estate boom on that island didn't pan out and economic damage from the Great Fraser Flood of 1894 led to the municipality's disincorporation on March 12, 1906. Another municipality eastwards, Nicomen, was incorporated in the same year but similarly later disincorporated. Though in the same school district as Mission, it and other adjoining rural areas did not join that municipality when offered. It is now represented as part of Electoral Area 'G' in the regional district government, which currently is the Fraser Valley Regional District. Dewdney is located at the western end of Nicomen Island, one of the larger settled islands in the Fraser, and at the southeast corner of Hatzic Prairie, a lowland floodplain at the south end of which is Hatzic Lake, an oxbow lake with a community of the same name on the island in its centre. Downtown Dewdney spans the Nicomen Slough, which is fed by Norrish Creek (aka Suicide Creek), one of the main water supplies for the District of Mission. Running east on the north side of the slough is the famous Hawkins Pickle Road (famous mostly for its name). Dewdney has a couple of stores, a post office, the Historic Dewdney Pub (aka "Church of the Blues"), the Dewdney Elementary School featuring a Community Outdoor Recreation Education program, and other businesses and is a service centre for other nearby communities, most of which are more rural in character. Though situated in rich farmland Dewdney also has a history and continuing economic presence in lumbering and milling community, and also in relation to the fishery and shipping on the river Dewdney was the destination of the Dewdney Trunk Road, one of the Fraser Valley's earliest main roads, which ran from Port Moody to Dewdney. The Dewdney Trunk Road, or Dewdney Trunk as it is often called, should not be confused with the Dewdney Trail, which is a colonial-era route from Hope to the East Kootenay region built by Edgar Dewdney. He had been in charge of surveying the site of New Westminster during colonial times and had served on the Legislative Council, the colony's governing body, and as Member of Parliament. The community of Dewdney was named in 1892 when he was appointed Lieutenant-Governor of British Columbia and who had been Lieutenant-Governor of the Northwest Territories from 1881, and federal Minister of the Interior from 1888–1892.

Dewdney Peak, also known unofficially as Hatzic Mountain, is the southwesternmost summit of the Douglas Ranges in the Lower Mainland of southern British Columbia, Canada. Dewdney Peak is located east of Hatzic Prairie and north of Dewdney, British Columbia, from whence it got its name.

Hatzic Island is an island located in the centre of Hatzic Lake, an oxbow lake formation north of the Fraser River, on the east side of Mission, British Columbia, Canada.

Hatzic Lake is an oxbow lake north of and draining into the Fraser River, immediately south of Hatzic Valley, and east of the benchland neighbourhood of Hatzic. Neilson Regional Park and the district of Mission is on the immediate west shore of Hatzic Lake, while the centre of the oxbow is Hatzic Island. Northeast of the lake is Dewdney Peak (Hatzic Mountain) which forms the southmost endpoint of the Douglas Ranges. In addition to a large number of private residences the locality has a few commercial campgrounds. Hatzic Valley's Lagace Creek, Scorey Creek, and Hatzic Slough drain into the northern end of Hatzic Lake, providing it with water. Since these tributaries are intermittent, the water freshness and level of Hatzic Lake can vary seasonally. The length of the lake, on its north–south axis, is approximately 3.7 km, while Hatzic Island is approximately 2.6 km in length, with the widest parts of the lake off the northern end of the oblong island at about 775 m. The width of the lake inclusive from its extreme west to east is about 2.5 km. BC Highway 7 and the mainline of the Canadian Pacific Railway cross its southern end, just south of the southernmost parts of Hatzic Island. The depth of the lake is a uniform 2 to 3 meters, except immediately north of Hatzic Island to west of Hatzic Island where depth varies between 3 and 15 meters. Because the lake is surrounded with private residences launch sites for non-residents' boats are limited and smaller boats tend to be launched from Neilson Regional Park or near Hatzic bridge on Lougheed Highway.Because the lake is very shallow it is warm, and is popular for swimming, water sports and water-skiing. The lake water temperature and farm fertiliser run-off introduced via Scorey Creek has been blamed for invasive flowering rush and algal bloom issues, the latter of which has led to Fraser Health-imposed swimming bans. In 2019 the BC Government funded over a quarter million dollars for addressing invasive plant concerns in Hatzic Lake.

Hatzic is a historic community in the Central Fraser Valley region of the Lower Mainland of British Columbia, Canada, located on the east side of the City of Mission and including areas beyond the municipal boundary to the east and northeast. Hatzic is the location of two very important historical sites in British Columbia, the mission school of the Oblate Fathers (OMI), St. Mary's Indian Residential School, the name sake of the City of Mission, and Xá:ytem, an archaeological site and museum dating back over 9,000 years. Xá:ytem is a National Heritage Site of Canada. Also notable is Ferncliff Gardens, a private floral operation now becoming a heritage site. Hatzic Slough, which is part of the drainage for the oxbow Hatzic Lake, is the site of one of the world's largest dry-sorting yards for raw timber. A former railway station named Hatzic was located between the outlet of Hatzic Lake and the foot of the rise to the benchland where most of residential Hatzic is today.Mission's Fraser River Heritage Park is to the west and incorporates lands formerly belonging to the Oblate mission, including the foundations of the original school, though it is accessed from Mission proper, not via Hatzic. Hatzic is one of Mission's older suburban neighbourhoods and is home to Hatzic Secondary School and various elementary schools. Overlooking it from above is Westminster Abbey, a Benedictine monastery established in the 1950s, which is part of the Ferndale neighbourhood of Mission. Across the floodplain from the benchland Hatzic proper overlooks and where Hatzic Valley is located is the community of Dewdney, standing astride the bridge where British Columbia Highway 7 leads onto Nicomen Island. Across the Fraser River from Hatzic is the northeast sector of Matsqui Prairie.

Norrish Creek is a tributary of the Fraser River. It is located in the Douglas Ranges, the southernmost subrange of the Pacific Ranges of the Coast Mountains of British Columbia, Canada to the north of Nicomen Island. Local residents refer to it as "Suicide Creek." It was named after William Henry Norrish a pioneer Scottish Canadian farmer.: 192 

X̱á:ytem () is an indigenous archaeological site and the name of a related museum run under the auspices of the Stoːlo people at Hatzic, British Columbia, Canada. X̱á:ytem is approximately 80 kilometres east of Vancouver on Highway 7. It is reached via the bridge at Mission, about 15 kilometres from the border with the US state of Washington. The site was designated in 1992 as a national historic site of Canada for its spiritual value to the Stoːlo people, as well as being one of the oldest discovered habitation sites at approximately 5000 years old. It was listed on the Canadian register of historic places in 2005. It is also known as Hatzic Rock National Historic Site of Canada.

Durieu is an unincorporated predominantly farming community, located around five kilometers northeast of Mission, British Columbia, Canada in Area F of the Fraser Valley Regional District of that province's Lower Mainland at an elevation of between twenty and forty meters above sea level. Durieu falls mostly within zone 1 of the Agricultural Land Reserve. Sited in the middle of Hatzic Valley it has few services other than a store, gas station, feed co-op, defunct elementary school and community hall. Hatzic Prairie's former post office was renamed to Durieu Post Office in remembrance of Archbishop Pierre-Paul Durieu around 1910. This in turn led to British Columbian government officials and cartographers using the name "Durieu" to describe the local settlement from 1939. Durieu currently holds community-level status per the BC Geographic names office.

Chadsey Lake, also known as Lost Lake, is located on Sumas Mountain near Abbotsford, British Columbia.

The Hatzic Valley is the southerly, lowland portion of the Fraser Valley Regional District Electoral Area "F" of British Columbia's Lower Mainland. The valley was carved as a result of southward glacial action, being "centered along a low‐lying glacial trough that extends from Stave Lake to the Fraser Valley."The perimeter of Hatzic Valley is described in the current British Columbian Official Community Plan document “Official Community Plan for Hatzic Valley, Electoral Area “F” Bylaw No. 0999, 2010”, published by the Fraser Valley Regional District, and which illustrates the valley as occupying the area from the southeast point of Stave Lake in the northwest to Hatzic Lake in the south.The valley is flanked on the eastern side by the Douglas Ranges, the ridge nearest the valley known as Durieu Ridge, the southern point of which forms Dewdney Peak. The valley includes the area occupied by Davis Lake Provincial Park and Mount St. Benedict in the north and that of Cascade Falls Regional Park in the northeast. The valley measures about 12.5 kilometers long from Davis Lake to Hatzic Lake, and about 2.5 kilometers wide at Durieu. The valley is home to approximately 1,300 people.Hatzic Valley in turn comprises various unincorporated communities, specifically Hatzic Prairie in the south, the town of Durieu in the center, and the localities of McConnell Creek and Miracle Valley in the north.
