Culvert Assessment and Projects
A comprehensive culvert assessment was done at all road crossings on Murray Creek in 2011. The scope of this project encompasses all known culverts within the agricultural area of the Murray Creek watershed, including both public road and private road or crossing culverts. However, due to landowner rights in Canada, only private culverts for which permission has been granted by the landowner were measured. Eight private culverts were measured, however, this leaves an estimated 5-7 culverts on private land in which the landowner could not be reached, or did not grant access to their land.
Six projects were completed in 2011 on Murray Creek.

Project 11-01:
General Description and issues: Removal of two undersized and hanging closed bottom culverts and construction of cobble/gravel based crossing using geo-grid.
Outcomes: Two undersized and hanging closed bottom culverst removed, and a cobble/gravel based crossing completed successfully. Approximately 300m of stream upstream of culvert is now accessible to fish.
Project 11-02:
General Description and issues: Removal of one undersized closed bottom culvert and construction of streambed prior to installation of an 1828mm span x 914 rise m open bottom culvert.
Outcomes: Removal of an undersized close bottom culvert and installation of an 1828mm span x 914mm rise m open bottom culvert. Approximately 800m of stream upstream of culvert is now accessible to fish.
Project 11-03:
General Description and issues: A combination of grazing activity, fine glacial-°©-lacustrine bank material and the blowout of a beaver dam have contributed to lateral stream movement and erosion of the stream bank in several places. The prescription included strategically placing rock armoring on the stream bank for increased structural integrity, and the planting of native (willow) and grass species, to prevent further erosion and sediment distribution downstream.
Outcomes: Approximately 110m of stream bank was armoured and stabilized preventing further erosion and sediment deposition.
Project 11-04:
General Description and issues: Removal of three undersized closed bottom culverts and construction of streambed prior to installation of a 2438m Span x 1219mm Rise Dur-A-Span Arch.
Outcomes: Three undersized closed bottom culverts removed and installation of a 2438m Span x 1219mm Rise Dur-A-Span Arch. Approximately 650m of stream bank upstream of culvert is now accessible to fish.
Project 11-05:
General Description and issues: An existing crossing was in poor condition. A prescription to upgrade and construct a cobble/gravel based crossing provided a hardened watering site for livestock to drink and cross at the stream, and will allowed for infrequent crossing of farm equipment.
Outcomes: Crossing upgrade completed successfully, permitting the reduction of erosion and sediment deposition from unfettered livestock access to the stream.
Project 11-06:
General Description and issues: An existing crossing was in poor condition. A prescription to upgrade and construct a cobble/gravel based crossing provided a hardened watering site for livestock to drink and cross at the stream.
Outcomes: Crossing upgrade completed successfully, permitting the reduction of erosion and sediment deposition from unfettered livestock access to the stream.
