Three reaches were designated based on: Land use and a tributary. In the first reach Scour Pools (72%) and Riffles (25%) dominated the habitat, while silt/organics (18%), sand (41%), and gravel (35%) were the dominant substrate types. In the second reach Riffles (49%) and sour pools (41%) dominated the habitat, while silt/organics (16%), sand (38%), gravel (30%) were the dominant substrate types. In the third reach, riffles (68%) and scour pools (25%) dominated the habitat, while silt/organics (20%), sand (40%), and gravel (30%) were the dominant substrate types. The survey begins at the confluence of the Nehalem River. An ODFW Spawning Survey sign was not noted. The survey had some nice spawning gravel throughout. There was a lack of off-channel habitats. Survey ends as stream flow diminishes in reach 3. REACH DESCRIPTIONS: REACH 1: Length 401 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 0.6%. The channel characteristics include: primary 401m and secondary 31m. Five pools were greater than 1 meter deep, which averages to 11.6 deep pools per 1 km. There were zero key pieces of LWD. The vegetation is based on 2 riparian transects. The trees found most frequently in the riparian zone were mostly mixed sizes of deciduous ranging from 15 30 cm dbh, with some mixed conifers and deciduous 30 50 cm dbh. This survey begins at the confluence with the Nehalem River where there was no ODFW Spawning Survey sign. The reach is predominately rural residential, and some landowners have horses whose fields are fenced on the right terrace. Not far from the confluence there is a water intake diversion at one of the houses, the surveyors could not determine if it was a screened or unscreened diversion. One landowner has cut and cabled some logs for riprap to prevent bank erosion, but is also creating some nice pools. This landowner, Lee Duval who spoke to the surveyors, seemed concerned about the possibility of loosing his fence due to some erosion of the stream bank. Not far up from this point there is an old decommissioned road crossing. Reach 1 ends at a culvert crossing under Weed Creek Road, at a change in land use. The culvert is passible, but the opening section is starting to degrade and at the upstream side there is a step (0.3m) over log which is clogging the culvert with some debris. This reach lacks off channel habitat, which is comprised solely of a few backwaters and an isolated pool, there are no secondary channels. There is good LWD project potential with good access for industrial equipment. The biggest drawback to a future LWD placement project will be the close proximity of houses to the stream channel, but opportunities still exist. There is a good mix of conifers and alders. So, a planting project is not necessary. REACH 2: Length 1,114 meters. The channel is constrained by terraces in a broad valley. The average valley width index is 5.3. Land use for the reach is second growth, a sub dominant land use was observed to young timber. The average unit gradient is 2.2%. The channel characteristics include: primary 1,114m and secondary 67m. Zero pools were greater than 1 meter deep. There were four key pieces of LWD, which averages to 0.4 key pieces per 100m. The vegetation is based on 2 riparian transects. The trees found most frequently in the riparian zone were mostly mixed sizes of deciduous ranging from 30 - 50 cm dbh, with some mixed conifers and deciduous 15 - 30 cm dbh. Reach 2 begins at the culvert crossing where there is a land use change as the stream leaves rural residential and enters industrial timberland operated by Longview Fibre. There continues to be sections of the stream with good spawning gravel, but less when compared to Reach 1. There were some sections of the stream where hardpan clay comprised some of the substrate. A blown out beaver dam was located near the end of the reach. At unit 60, just below a tributary junction on the right , there was a large cut log on the bank that could be used for LWD placement. The tributary on the right does have good future project potential as there is a logging road through a newly installed plastic culvert, which could be a potential velocity barrier for juvenile salmonids. Reach 2 lacks and secondary channels, and its off channel habitat consists of backwaters. Reach 2 ends at an small unnamed tributary junction on the right. There is good LWD project potential with fair access for industrial equipment. The major landowner is already trying minor stream habitat measures and would enjoy additional work in the future. The riparian has a mix of conifers and alders and the landowner has planted additional plantings along the right side. So, a planting project is not necessary REACH 3: Length 1,114 meters. The channel is constrained by terraces in a broad valley. The average valley width index is 5.3. Land use for the reach is second growth, a sub dominant land use was observed to young timber. The average unit gradient is 2.2%. The channel characteristics include: primary 1,114m and secondary 67m. Zero pools were greater than 1 meter deep. There were four key pieces of LWD, which averages to 0.4 key pieces per 100m. The vegetation is based on 2 riparian transects. The trees found most frequently in the riparian zone were mostly of conifers ranging from 30 - 50 cm dbh, with some mixed conifers and deciduous 3 - 15 cm dbh. Reach 3 begins at a tributary junction on the right in conjunction with a past timber harvest unit on the left side. The timber harvest has already been replanted. There were a number of blown out or partially blown out beaver dams in this reach. In addition, there were a number of trees from the timber harvest buffer, which have been blown into the creek. The stream also begins to become bushy with salmonberry and devils club, which is completely growing over the creek in a number of different units. About halfway through the reach there is a more recent timber harvest on the right hillslope above a decommissioned logging road. In the last quarter of the reach, the riparian becomes very nice with great shade cover and large conifers. There remains to be a number of pockets of good spawning gravel in this reach, but not as significant as in the first two reaches. Additionally, there were a number of units that were scoured to bedrock. There continues to be a lack of off-channel habitat despite an increase in in-stream LWD in this reach. The survey ended at a major split where the habitat becomes marginal above. There is an old decommissioned logging road at the end point, with riprap in the creek. There is good LWD project potential with fair access for industrial equipment. Access may be improved with further planning. Although, this reach was given priority for LWD placement, the lower reaches 1 and 2 have more potential to create off-channel habitat. The riparian has a mix of conifers and alders and the landowner has planted additional plantings along the right side. So, a planting project is not necessary.

There were four key pieces of LWD, which averag}{\insrsid543861 es to 0.4 key pieces per 100m.}{\insrsid543861\charrsid543861 }{\insrsid543861 The vegetation is based on 2 riparian transects.

The stream also begins to become bushy with salmonberry and devil\rquote s club, which is completely growing over the creek in a number of different units. }{\insrsid543861 \par \par }{\insrsid14171829 About halfway through the reach there is a more recent tim ber harvest on the right hillslope above a decommissioned logging road. In the last quarter of the reach, the riparian becomes very nice with great shade cover and large conifers. There remains to be a number of pockets of good spawning gravel in this r e ach, but not as significant as in the first two reaches. Additionally, there were a number of units that were scoured to bedrock. There continues to be a lack of off-channel habitat despite an increase in in-stream LWD in this reach. The survey ended a t a major split where the habitat becomes marginal above. There is an old decommissioned logging road at the end point, with riprap in the creek. \par }{\insrsid543861 \par }\pard \ql \li0\ri0\widctlpar\aspalpha\aspnum\faauto\adjustright\rin0\lin0\itap0\pararsid543861 {\insrsid543861 There is good LWD project potential with fair access for industrial equipment. Access may be improved with further planning. Although, this reach was given priority for LWD placement, the lower reaches 1 and 2 have more potential to create off-channel habitat. The riparian has a mix of conifers and alders and the landowne r has planted additional plantings along the right side. So, a planting project is not necessary. \par }\pard \ql \li0\ri0\widctlpar\aspalpha\aspnum\faauto\adjustright\rin0\lin0\itap0 {\insrsid543861 \par }{\insrsid14171829 \par \par \tab }}2,2,2,2 Twhile silt/organics (19%), san00 0 0000p00p00p000i&[ $i&i&=c->c\,?c 7@c.Acl.Bc| Cc,/c0c$/1c'2cL13c|04c/5cD!8c#9c$:c%;cd'GV_k%8ak::rj\ G^8`ahkV_kTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellTodd Landon BoswellMark McLaughlinuL@``Ӓ``i@@UnknownGz Times New Roman5Symbol3& z Arial"qh!e9e77!24ZZ 3H(?uLBen Todd Boswell,2,!,,,!','2,22,2!N,!/222N,2222 secondary 31m.
