Instream and Environmental Flows

Our team provides specialized services to support clients in developing sustainable water management practices. We have extensive experience in the assessment, mitigation, and monitoring of flow-related effects to the aquatic environment. We have built our reputation in the industry by developing tailored solutions that blend two decades of experience with in-house data and modeling capacity, allowing us to provide cost-effective and successful support for projects that will affect stream hydrology. We have supported numerous clients by characterizing the existing environmental conditions and conducting objective, science-based assessments, engaging with Indigenous peoples, regulators, other project stakeholders, and collaboratively developing water management practices that minimize effects to the aquatic environment.

How We Can Help

Environmental Flow Needs (EFN) assessments for short-term water use (Section 10 of WSA) and long-term conditional water licenses
Screening-level assessments to inform project design and identify environmental and permitting risks associated with water use
Regulatory support, including strategic advice, permitting, and third-party reviews (e.g., BC Water Sustainability Act, Fisheries Act)
Developing strategies to mitigate the effects of water use on the environment, e.g., water management plans
Assessment of wetlands, streams, and groundwater-surface water interactions to support provincial and federal permitting requirements for water use and footprint activities
Ecohydraulic modeling (e.g., PHABSIM, SEFA) to develop predictive relationships between streamflow and ecological indicators
Guideline—compliant ecological assessments for water management activities, e.g., consumptive water use for process plants or dust management, flow diversion, dewatering activities, water treatment
Assessment of change in water level and flow downstream of project activities for compliance with the Fisheries Act
Assessment of predicted climate change impacts to environmental flows for regulatory requirements
Engagement with First Nations and communities on water use plans and potential effects of project activities on the aquatic environment
Long-term monitoring of the effects of water use on the environment through field studies and adaptive management
