Water is a resource shared by multiple uses, ranging from drinking water supply to agriculture, industry, leisure, and recreational tourism. This diversity of uses can create tension when the needs of some stakeholders come into competition with those of other users.

Periods of drought, seasonal variations in streamflow, and climate fluctuations increase pressure on the resource and complicate water management.

Competing water use

Across the Rivière du Nord watershed, the diversity of activities and ongoing population growth exacerbate this phenomenon. Water‑use conflicts occur when one group’s needs negatively affect or restrict those of another. In particular, they can take the form of:

  • tension between protecting water quality and motorized or recreational uses
  • difficulties in balancing agricultural irrigation with maintaining ecological flow rates
  • issues of public access to private or heavily used water bodies

Population growth, the popularity of recreational tourism and leisure, as well as the growing needs of water for agriculture and certain industries accentuate these sometimes-difficult situations of coexistence, particularly around the most frequented lakes and rivers.

Did you know?

More than half of the water-use conflicts identified in the watershed involve coexistence between recreational activities (watercraft, fishing, swimming) and the protection of aquatic environments.

Location within the territory

The challenges of reconciling uses are particularly pronounced in the densely populated and tourist areas of the southern part of the watershed. These can especially be observed:

  • around lakes used for recreational purposes (Masson, Raymond, Rond, des Sables)
  • in the municipalities of Saint-Jérôme, Prévost, and Sainte-Sophie, where residential growth and water supply needs are increasing
  • near major recreational tourism hubs, such as ski areas and golf courses, whose activities require large volumes of water

These varied, sometimes competitive, uses require integrated management of the territory to ensure the sustainability of the resource and harmonious coexistence between users.

Main causes

Water is a collective resource, but no legal framework defines clear priorities between the different uses. Several factors therefore contribute to tensions between stakeholders:

  • Major water withdrawers: agriculture, industry, and municipalities consume large quantities of water, sometimes in competition with each other during periods of low availability.
  • Drinking water supply: human needs may exacerbate competition when the available volumes are limited.

  • Shoreline urbanization reduces access to lakes and watercourses, and certain facilities (private beaches, special ramps) may restrict use and degrade aquatic environments.

  • Poor water quality limits swimming, fishing, and drinking water supply.
  • The degradation of wetlands affects several ecological services (pollutant regulation, habitat, aesthetics), impacting all stakeholders and multiplying conflicts.

  • the region attracts vacationers and tourists every year. The water bodies are used for numerous activities (swimming, sailing, sightseeing, water sports) as well as for the development of recreational tourism companies (golf, inns, resorts).
  • Recreational uses coexist with more intensive activities (artificial snow production, irrigation), which can create pressure on the resource.

  • The lack of scientific information and communication between managers and users can lead to misunderstandings and conflicts.

Climate change

Climate change is likely to intensify the tensions around water within the Rivière du Nord Integrated Water Management Zone (ZGIE). Longer droughts and extreme rainfall events may reduce river flow rates and groundwater recharge, limiting availability for municipalities, agriculture, and industry. Rising temperatures and increased precipitation also promote the eutrophication of water bodies, which affects swimming, fishing, and the health of aquatic ecosystems. Accessing watercourses to cool off could become more frequent, increasing pressure on recreational uses. These challenges highlight the importance of concerted and equitable water management to preserve both human uses and the resilience of aquatic environments.

Consequences 

Environmental

  • Degradation of riverbank and aquatic habitats
  • Insufficient ecological flow rates required for the health of watercourses
  • Accelerated aging of lakes and rivers

Social

  • Tensions and conflicts between water stakeholders
  • Degradation of trust toward management and regulatory bodies
  • Reduced quality of the recreational experience

Economic

  • Damage to the tourist image of certain water body
  • Limitations to the development of certain uses
  • Costs associated with monitoring, signage, and the enforcement of regulations

Prioritized issues
