DESCRIPTION
The primary objective of the Frase Creek Barrier Removal is to replace an existing fish passage barrier with a fish passable structure. Culvert 021(64022)(00529) is an existing 2.13 m x 1.52 m (7 ft x 5 ft) corrugated metal squash pipe, located at MP 0.529 on Pigeon Springs Road, on Frase Creek. This culvert is under ownership of Lewis County. It was calculated to be 0 percent passable due to a 1.16 m (3.8 ft) outfall drop, a slope of 2 percent and lack of substrate within the culvert. The culvert is ranked 18th for replacement within the upper Chehalis Basin and 11th for replacement within Lewis County. Replacement of this culvert is anticipated to restore access to an additional 2.74 linear miles of potential habitat; 8,442 square meters (2.89 acres) of rearing habitat and 388 square meters (0.10 acres) of spawning habitat. A priority index has not been generated for this culvert.

Half an acre of stream bank was also replanted to restore disturbance caused from construction activities.
