DWWP Quick Facts

This subsection of Water Region 6, the Nanaimo River Water Region, covers the communities of Cassidy, South Wellington, Cedar and Yellow Point.
The Nanaimo River and Haslam Creek run through this area, but the main water supply for residents here is groundwater from the aquifers that underlie the area: sand and gravel aquifers in Cassidy and bedrock aquifers in Cedar-Yellow Point.

Base Layer

Land Use

In the lower Nanaimo River Water Region, there is farm-related land use, rural residential areas, the village centre of Cedar. This coastal lowland is the populated area, whereas the upper Nanaimo River Water Region is unpopulated forestry land.

The Regional District of Nanaimo Electoral Area that comprises the majority of lower Water Region 6 is Area "A", which has Area A -Official Community Plan (OCP) to guide development. There is also a small portion of Electoral Area "C" in the village of Extension that overlaps this area.

The RDN has an Agriculture Area Plan that contains a regional strategy for sustainable farming and related land uses.

The southern boundary of this water region overlaps into the Cowichan Valley Regional District.

Water Supply

The lower Nanaimo River Water Region contains the groundwater sources which provide water to the rural communities of Cedar, Yellow Point, Cassidy and South Wellington.

Rural residents supply their own water from private wells (indicated by the pink dots on the map). The RDN wellSMART program provides information on private wells.

There are three notable small community water systems in this water region, that provide groundwater to residents:

The City of Nanaimo water supply also extends into this water region, on the Snuneymuxw First Nation Reserve #2 and at Duke Point.

Island Health Authority is responsible for the oversight of drinking water quality in community water systems.

Education and networking opportunities exist for smaller water system operators, such as mobile home parks, restaurants, campsites, gas stations etc. The Water Purveyor Working Group meets annually, click here for details.

Team WaterSmart has information on what you can do to conserve and protect our water supply.


In this water region, there are bedrock aquifers and sand and gravel aquifers that are the main source of drinking water in the areas outside the municipality of Nanaimo. Aquifers are underground areas that store water, either in bedrock fractures or in the pore space between sand and gravel. This includes provincially mapped aquifers 162, 164, 165, 168, 963, 964 (bedrock) and aquifers 160, 161, 163 (sand and gravel). See the BC Water Resource Atlas for a close-up map of these aquifers.

Groundwater monitoring is ongoing in this region, with Provincial Observation Wells:

  • (#228) in Cassidy at Timberlands Road that monitors water levels in surficial sand and gravel aquifer 160.
  • (#312) in Cassidy at Haslam Creek T-Bridge that monitors water levels in surficial sand and gravel aquifer 161.
  • (#337) in Ladysmith at Woodley Range that monitors water levels in bedrock aquifer 162.
  • (#390) in Cedar on Holden-Corso Road that monitors water levels in bedrock aquifer 162.
  • (#432) in Yellow Point at Quennell Road that monitors water levels in bedrock aquifer 162.
  • (#435) in South Wellington that monitors water levels in bedrock aquifer 165.

The Provincial Water Protection and Sustainability Branch is responsible for groundwater legislation.

For more on groundwater and aquifers, see Aquifers 101.

Streams & Waterbodies

The lower part of Water Region 6 is home to smaller creeks that drain the lowland area near the coast, such as Beck Creek, Hemer Creek and Hokkanen Creek. The lower reaches of the dominant rivers in this system, the Nanaimo River and Haslam Creek pass through the Cedar - Yellow Point - Cassidy area.

These waterways are important for fish habitat and recreation.

Key stewardship groups that are active in this region include: the Nanaimo and Area Land Trust and the multi-stakeholder communications group, the Nanaimo River Watershed Roundtable.

Streamflow is monitored a Water Survey of Canada hydrometric gauge in the lower Nanaimo River near Cassidy.

The Province of BC is responsible for freshwater regulations, see the Water Sustainability Act for more information.

The RDN Phase 1 Water Budget Study (2013) looked at supply and demand on surface water resources in Water Region 6, based on available data.

First Nations Significance

This water region is within the traditional territories of the Snuneymuxw First Nation and the Stz'uminus First Nation . This area is rich with cultural significance and the waters and lands are closely connected with First Nations peoples and their ancestors.

There were six Salish languages (Hul'qami'num, Snuneymuxqun, Sqo'mish, she shashishalhem, Tla'amin, Comox, and Pentlatch) spoken traditionally in the RDN. In addition, Nuu chah Nulth, Kwakwala, and Sencothen languages would also bump up against the boundaries of the district. And Chinook was also used as a trading language.

Each piece of land is known by different families, communities, First Nations, dialects and languages by similar and dissimilar names. The land belongs to the name. The name does not belong to the land. In this way, there is more than one "Qualicum", for example: one near Port Renfrew and one also near Bellingham.

We have recorded here (in partnership with School District 69) as many names as we have been able to find. We recognize that more names are out there, and we are always happy to include them if you are open to sharing with us. Email: creid [at] sd69.bc.ca

Traditional ecological knowledge is vital to understanding our watersheds and their health.

Community Programs

RDN Rebates Rebate programs are available for residents across the region to conserve and protect water. Currently being offered are: The RDN's Team WaterSmart offers education and outreach programs across the region. They provide activities and resources on water conservation indoors and outdoors, water quality protection, and ecological values.
  • Workshops
  • Irrigation Initiatives
  • Brochures
  • Events Calendar
School education opportunities are also offered across the region including:
  • Classroom Visits
  • Field Trips
  • Teacher Professional Development
Volunteer opportunities are sometimes available for private well owners, stream stewards and more.
