Under the Water Sustainability Act (WSA), "changes in and about a stream" means:
- Any modification to the nature of the stream, including any modification of the land, vegetation and natural environment of a stream or the flow of water in a stream, or
- Any activity or construction within a stream channel that has or may have an impact on a stream or stream channel
Under the WSA, "stream" means:
- A natural watercourse, including a natural glacier course, or a natural body of water, whether or not the stream channel of the stream has been modified, or
- A natural source of water supply,
including, without limitation, a lake, pond, river, creek, spring, ravine, gulch, wetland or glacier, whether or not usually containing water, including ice, but does not include an aquifer.
Under the WSA, "stream channel", in relation to a stream, means the bed of the stream and the banks of the stream, both above and below the natural boundary and whether or not the channel has been modified, and includes side channels of the stream.
Change approvals
A change approval is a written authorization to make changes in and about a stream. You do not require a change approval if the changes are associated with construction of works that are authorized in a water licence. Change approvals are granted with terms and conditions attached. The terms and conditions may relate to the time of year in which you may undertake the work or other measures that protect the aquatic ecosystem, the hydraulic integrity of the stream channel and the rights of water users and landowners downstream.
Regional terms and conditions and timing windows
The authority to work in and about a stream, either through a change approval or notification, is generally granted with terms and conditions attached. Terms and conditions vary from region to region, and work in each region is generally restricted to specific times of the year called regional timing windows.
If you are granted a change approval, terms and conditions will be specified as part of your approval.
Note: Marine/saltwater is not included within the definition of a "stream" or a "stream channel" under the Water Sustainability Act.
Costs and responsibilities
You will be charged an application fee when you apply for a change approval. If the works cross Crown land you may require a permit, for which a separate fee is charged. Fees are calculated automatically as you complete the online application. Read about Water application fees and rental rates and estimate your costs.
Fees can be paid online at the time of application, or at a FrontCounter BC location. See Payment guidelines for more information.
Most application fees are non-refundable. Check the Policy: Refunds for Applications (PDF, 105KB) for more information.
