- Know the
different options for improving fish habitat in your watercourse.
This section of the manual will outline some basic choices.
Although you will rely on a NSSA professional to guide you,
it is important for you to understand different methods.
- Pick the right "tools" and treatment for your stream. Each
stream is a unique ecosystem. Its best condition is determined
largely by the soils and vegetation in the surrounding area.
Each stream, therefore, must be viewed as unique, with individual
problems and solutions. Enhancement measures used successfully
on one stream may not work for another.
- Make sure you have completed a watercourse plan and have read
about legal and safety considerations outlined later in this
section.
- Make sure you have obtained all the necessary permits to work
in the watercourse (see the previous section). |
Here are some
typical devices:
-Digger logs - hardwood logs set across the stream bottom at
various angles depending on the stability of the bank and where
the pool is needed. Logs are held in place by re bar pins and
rocks.
-Vegetation - planting native vegetation like willows along
streams with low eroding banks will collect sand and silt and
re-build the channel.
-Deflectors made out of rock or wood - In wood deflectors, mature
trees are dropped parallel to the bank and tied to their stump.
Deflectors are used in areas where silt and sand needs to be
collected. |
