All of us at Denbow realize the importance of fish habitats and protecting the fish from urban development. We believe it is essential that we all understand the best practices for working around fish habitats and streams. We’ve adapted a short guide to help you understand what you must know before you work in and around a fish habitat. This guide does not replace any legal or contractual obligations; it simply shares information and offers an education on the best practices in erosion and sediment control in and around a fish habitat.
What is A Fish Habitat?
Under the Fisheries Act, a fish habitat is defined as “Spawning grounds and nursery, rearing, food supply and migration areas on which fish depend directly or indirectly in order to carry out their life process (Fisheries Act Section 34(1))”.
In other words, the habitats include not only the water in rivers, lakes, streams and oceans, but also the quality of that water. Furthermore, the total surroundings in which plants and other life forms interact to make fish life possible are considered. The vegetation adjacent to the waterway is a critical part of fish habitat as it provides nutrients, shade and buffers waterways from sedimentation and pollution during surface runoff.
What is Contained in the Fisheries Act?
Prohibitions unless authorized include the following:
Cannot install or allow any material (rock, log, slide, dam, perched culvert) to impede the free passage of fish at all life stages.
Cannot destroy fish by any means other than fishing.
Cannot change the natural courses and processes of fish habitat.
It is unlawful to deposit a harmful substance either directly or indirectly into a fish-bearing stream. This includes the top of banks or ditches that lead to a fish-bearing stream. Deposit means any discharging, spraying, releasing, spilling, leaking, seeping pouring, emitting, emptying, throwing, dumping or placing.
Deleterious (toxic or harmful) means any substance (e.g. petroleum products, concrete wash, soil/sediment) that is harmful to fish, water quality or limits the use by fish. It can also be considered deleterious if the material impairs a fish's ability to reproduce, to capture its food, to make the transition from freshwater to the sea, or if it causes a fish to be more susceptible to disease or predation.
One way to prevent soil and sediment from entering a stream is to implement a sediment control barrier. This can be done by using FilterSoxx™ to prevent the sediments from running into the stream.
Working In and Around A Fish Habitat
Prior to Starting Work Know Your Plan and Avoid Problems!
What You Can Do
Make sure you do your due diligence. Don’t take someone’s word for it. Fish habitats are really important and with proper research and applications, it can easily be protected.
Therefore, it is your responsibility when working in and around water to ensure the following:
Avoid a HADD (Harmful Alteration, Disruption, Destruction)
Work near streams can usually avoid a HADD of the fish habitat if the work spans the stream (including streambanks) or can be undertaken without:
A stream channel is defined as:a watercourse that contains flowing water at least part of the year, in other words it can still be a stream if it is dry or partially dry.
An active floodplain is the level area adjacent to the stream that water periodically floods into.
What You Cannot Do
We know this seems a little obvious but let’s do our due diligence and make sure you don’t cause an unauthorized HADD.
Any works within the fish habitat (including the water and the surrounding riparian area/vegetation) has the potential to create a HADD unless precautions are taken. This is easily addresses by implementing streambank restoration solutions such as Filtrexx FilterSoxx™ or Terraseeding to prevent erosion and sediment run off.
If work near a stream or in a stream will result in a HADD, you must have an Authorization from Fisheries and Ocean Canada before commencing work. All other works are assumed to be completed without creating a HADD.
For Crossing Sites, unless authorized, this means there should be absolutely NO:
Be Aware of the Fisheries Window
Timing windows (periods of least risk) are periods of time when work in and about a stream can be conducted with reduced risk to fish and fish habitat. Anytime that any works come into contact with or impact a fish habitat, they are considered “instream works”. Be incredibly diligent with your SOP around critical and non-critical fish migrations.
Although the timing window is a time of reduced risk, fish (juvenile or adult) may still be present on site. Care must still be taken to avoid harming fish and fish habitat. This is the whole point of educating and informing us all about working around water ways. We need to protect the fish.
It is a period of time, when notifications are completed and a suitable plan is in place, that equipment can cross or work within a stream.
Ministry of Environment Notifications are required for any instream works (work within or on the banks of a stream, equipment within/crossing the stream) as per Section 9 of the Water Act. Notification can be made on the following site: http://wlapwww.gov.bc.ca/vir/wateract/index.html
Outside the timing window you can proceed if:
During a timing window you can proceed if:
You have completed the necessary notifications and a suitable plan is in place. The plan should capture the following:
Timing windows as listed in provincial and federal documents are approximations and may be varied with consultation of local agencies. Water temperatures, water levels and fish growth stage are an integral part of determining local fisheries windows.
What is an Environmental Monitor?
An environmental monitor's primary job requirement is to study the natural world and to make sure that human activities don’t harm the environment. For example, an environmental monitor working for a mine would spend most days outdoors collecting samples of water, air, land, and plants. They would measure the dirt roads, making sure the roads don’t erode into the nearby creek and create silt in the creek (which would probably kill any fish in the creek). They’d collect all of this data out in the field and send it back to labs for analysis. Environmental monitors generally work for government departments, environmental boards, large corporations, and consulting companies.
Job duties
Duties vary significantly from job to job, but the following list includes typical job duties an environmental monitor would be responsible for:
Role of the Environmental Monitor
The Environmental Monitor (EM) is on site to:
The EM must have input into or be on site prior to the site being accessed by construction crew for the following:
In conclusion, work around streams is sensitive but there are great solutions available. Natural products to control sediment and erosion, as well as installation methods such as blower trucks that allow for these products to be placed with no impact to the fish habitat. We recommend the use of an environmental monitor or consultant to ensure all work is completed properly within the laws and guidelines of your project location.
