CHAPTER 50 – AQUATIC HABITAT MONITORING
51 - ROAD CONDITION SURVEY
Road construction, presence and maintenance can negatively affect the function of downslope
aquatic ecosystems and the quality of the fish habitats provided by the aquatic ecosystem. The
Anadromous Fish Habitat Assessment report expressed concern about the negative effects of
road construction and maintenance on fish habitat. Roads can potentially create areas of
hillslope instability resulting in landslide generation, contribute fine sediment from surface
erosion, block fish migration, and alter surface and subsurface water flow patterns.
The road condition survey (FSH 7709.58-98-1, chapter 12.5) is a monitoring tool for determining
potential risk to aquatic ecosystems within the watershed. Application of the road condition
survey will identify both general risks and site-specific problems that may have either a direct or
cumulative effect on the aquatic ecosystem.
