The Hanna Tintina watersheds contain 80% of the spawning sockeye in the Nass River Drainage as well as bull trout, a blue listed species. The high concentration of sockeye salmon results in this drainage having a provincially significant Grizzly Bear population. The Pine Flats creek watershed contains rainbow and bull trout and has been heavily harvested and roaded.
The Hanna Tintina watersheds are proposed Protected Areas due to the high habitat values. Investment in these watersheds will improve and stabilize water quality and therefore spawning habitat. Watershed restoration works will reduce sediment transport from road surfaces and fills into streams.
This report does not include site specific prescriptions or cost estimates due to budgetary constraints and the need for more detailed fieldwork on areas not accessed. Helicopter access is required to complete the remainder of the Hanna Tintina road systems. The inactivity of the Forest Licenses in the area has resulted in heavily brushed in roads reducing access but has also served to stabilize the road prism with root penetration. For a period of 4 years there were no licensees operating in this area, therefore there were no current road inspections to reference when completing the watershed restoration inventory. Prioritization of areas was based on local knowledge of the area.
A total of 68 km of road was inspected during the fieldwork component, resulting in 9.2 km of road requiring waterbarring, cross ditching and culvert removal. Additional
operational consideration is required due to the potential construction of the North West Transmission line and the resulting road access requirements.
