FISH ACCESS
MOSQUITO CREEK
|
Upstream access is permanently blocked at the Queens Road culvert.
The GVRD sewer line weir crosses the stream bed, but it does not block fish passage.
- Fish Ladder Project ---- main stream
Greater Vancouver Regional District (GVRD)
1996
Voluntary
The GVRD weir, which supports the sanitary sewer line, was fish passable prior to being repaired in 1996. When the repair work was done, large instream boulders were rearranged to add additional support to the weir. The changes eliminated existing jump pools and fish access. Access was re-established by building the fish ladder.
Under an agreement with the GVRD, the Mosquito Creek Stewardship Society inspects and maintains the ladder throughout the year. A year long Data Collection Project was carried out at the ladder in 1998-99 to evaluate fish access and bedload variations.
