Three reaches were designated based on: Land Use. In the first reach Scour pools (26%) and Riffles (72%) dominated the habitat, while silt/organics (15%), sand (50%), and gravel (25%) were the dominant substrate types. In the second reach Scour pools (13%) and riffles (77%) dominated the habitat, while silt/organics (15%), sand (26%), gravel (25%), and bedrock (22%) were the dominant substrate types. Riffles (93%) dominated the habitat in the third reach, while Silt/organics (28%), Sand (26%), and Gravel (25%) were the dominant substrate types. The survey begins at the confluence with the Nehalem River. An ODFW Spawning Survey sign was not noted. The first reach runs through terraces and ends a culvert crossing where the land-use changes. The second reach is a forested, rural residential reach. The third reach begins at an old timber harvest boundary where many blown out beaver dams were noted throughout. The survey ends at a 60/40 tributary junction. REACH DESCRIPTIONS: REACH 1: Length 489 meters. The channel is constrained by terraces in a broad valley. The average valley width index is 20. Land use for the reach is light grazing. The average unit gradient is 0.9%. The channel characteristics include: primary 489m and secondary 39m. Six pools were greater than 1 meter deep, which averages to 12.3 pools greater than 1 meter deep per kilometer of primary stream length. There were zero key pieces of LWD. The vegetation is based on one riparian transect. The trees found most frequently in the riparian zone were mostly mixed sizes of deciduous ranging from 15 30 cm dbh. This survey begins at the confluence with the Nehalem River. An ODFW Salmon Survey sign was not noted. The stream meanders through a field which is fenced on the right but not on the left. Elk traffic is heavy in this reach with numerous stream crossings. The riparian consists of alders with patches of little to no cover and patches of blackberry. The substrate is comprised primarily of sand, viable spawning gravel does not appear until halfway through the reach. Near the end of the reach there is a cattle bridge, which does not appear to be utilized. Reach 1 ends at a change in land use at a culvert crossing (potential barrier) under Tweedle Lane. There is a .3m drop and the upstream side has a 0.4m high step that is the result of riprap from Tweedle Lane. There is good LWD project potential with good access for industrial equipment. The stream has poor complexity, but there is some nice gravel for spawning. A 0.3m step at the culvert presents a potential artificial barrier for juvenile salmonids and should be incorporated into a future restoration project. The riparian consists of alders, grass and the occasional blackberry patch. So, a planting project that establishes conifers would be beneficial to increase LWD recruitment. REACH 2: Length 1,184 meters. The channel is constrained by terraces. The average valley width index is 7.4. Land use for the reach is second growth timber. A sub dominant land use was observed to be rural residential. The average unit gradient is 1.2%. The channel characteristics include: primary 1,184m and secondary 39m. Four pools were greater than 1 meter deep which averages to 3.4 pools per kilometer of primary channel length. There were seven key pieces of LWD, which averages to 0.6 key pieces per 100m. The vegetation is based on two riparian transects. The trees found most frequently in the riparian zone were mostly mixed sizes of deciduous ranging from 3 15 cm dbh with additional deciduous ranging from 15 30 cm dbh. Reach 2 begins at a change in land use, the stream leaves light grazing and enters forested rural residential land. There are some nice pockets of spawning gravel above Tweedle Lane, but not far above that many of the units begin to be scoured to bedrock. There is a general lack of LWD in this reach. The riparian continues to remain dominated by alders, with an occasional conifer. There was a lack of off channel habitat in this reach, with no secondary channels and only backwaters observed. Reach 2 ends at a change in land use. There is good LWD project potential, but poor access for industrial equipment. The lower half of the reach can be accessed via tweedle rd and the adjacent meadow above. However, the farther from tweedle rd the access for industrial equipment diminishes. The stream has poor complexity and there is still some nice gravel for spawning. The riparian consists of medium sized alders and some small conifers. Surveyors noted potential for increased conifer trees with the riparian. So, a planting project that establishes conifers would be beneficial to increase LWD recruitment. REACH 3: Length 556 meters. The channel is constrained by terraces. The average width index is 3.5. Land use for the reach is young timber. A sub dominant land use was observed to be second growth timber. The average unit gradient is 1.2%. The channel characteristics include: primary 556m and secondary 29m. One pool was greater than 1 meter deep which averages to 1.8 pools per kilometer of primary stream length. The vegetation is based on one riparian transect. The trees found most frequently in the riparian zone were mostly mixed sizes of deciduous ranging from 3 15 cm dbh with additional conifers ranging from 3 15 cm dbh. Reach three begins at a change in land use as there is an old but replanted timber harvest on the left hillslope. A number of blown out beaver dams were observed throughout the reach. A few pockets of spawning gravel was located in this reach, but there was still a lack of off channel habitat. Alders comprised the majority of the large timber in this reach. The entire stream needs additional LWD and pools as there are a number of long sections without each. At one point the wood and pools are numerous, it is limited to the last part of Reach 2. The survey ends at a major split (60/40) with a tributary junction on the right. The habitat above the split is still trout habitat, with some possible juvenile coho rearing in the first few pools. There is good LWD project potential, but poor access for industrial equipment. The stream has poor complexity and there is still some nice gravel for spawning. The riparian consists of medium sized alders and some small conifers. Surveyors noted a timber harvest that has been replanted, but there is still an abundance of alders and a lack of conifers. So, a planting project that establishes conifers would be beneficial to increase LWD recruitment.

The average unit gradient is 1.2%. The channel characteristics include: primary 556m and secondary 2 9m. One pool was greater than 1 meter deep which averages to 1.8 pools per kilometer of primary stream length. The vegetation is based on one riparian transect.

At one point the wood and pools are numerous, it is limited to the last part of Reach 2. The survey ends at a major split (60/40) with a tributary junction on the right.
