Two reaches were designated based on: Land use. In the first reach Scour Pools (18%), Riffles (22%), and Rapids (47%) dominated the habitat, while Sand (11%), Gravel (39%), Cobble (31%), and Bedrock (13%) were the dominant substrate types. In the second reach Riffles (64%) and Rapids (19%) dominated the habitat, while Silt/organics (17%), Sand (25%), Gravel (26%), and Cobble (19%) were the dominant substrate types. The survey begins at the confluence of the Nehalem River near a small yellow house on the upstream side of Hwy 47. An ODFW Spawning Survey sign was not noted in this very brushy confluence area. The first reach travel through a private landowner, but is still mostly forested except for his house and lawn. The second reach runs through timberland. Both reaches have fish passage barriers that need attention. REACH DESCRIPTIONS: REACH 1: Length – 165 meters. The channel is constrained by terraces in a broad valley. The average valley width index is 8. Land use for the reach is rural residential. A sub dominant land use of large timber was also noted. The average unit gradient is 9.4%. The channel characteristics include: primary 165m and secondary 0m. One pool was greater than 1 meter deep, which averages to 6.0 deep pools per 1 kilometer of primary stream length. 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 conifer and deciduous ranging from 15 – 30 cm dbh, with areas of grass noted. There are numerous sections of the stream that need additional shade cover. This survey begins at the confluence with the Nehalem River near Big Eddy park. Above the start point, there is a fenced field with a large amount of blackberry on the left bank. Shortly after the field the stream passes through a culvert crossing under Highway 47. Above the culvert, the stream is constrained by a concrete wall on the left, which holds back a yard in front of the Johns’ house. The stream then passes over a step over concrete structure, which does have a nice jump pool below, but still passes as a potential artificial barrier. Not far above this structure the stream passes through a metal shotgun culvert under a private road on the Johns’ property. The culvert on the left side is rusted through in some spots and is beginning to degrade. There is not much spawning gravel in this short reach, just pockets in the first riffle. There is no off channel habitat, as some sections of the stream are artificially constrained. A change in land use also occurs at the end of this reach. There is good LWD project potential, but the yellow house on the left may reduce opportunities. Any future project should include the replacement of the small concrete dam and old culvert that’s in poor condition. The riparian has is great above Hwy 47. Therefore, a planting project is not necessary except for the first 100m meters below Hwy 47. REACH 2: Length – 915 meters. The channel is constrained by terraces in a broad valley. The average valley width index is 3.7. Land use for the reach is large timber, a sub dominant land use was observed to young timber. The average unit gradient is 3.1%. The channel characteristics include: primary 915m and secondary 70m. One pool was greater than 1 meter deep, which averages to 1.1 pools per kilometer of primary stream length. There was one key piece of LWD, which averages to 0.1 key pieces per 100m of primary channel. The vegetation is based on 2 riparian transects. The trees found most frequently in the riparian zone were mostly mixed sizes of conifer and deciduous ranging from 30 - 50 cm dbh, with mixed conifers and deciduous 15 – 30 cm dbh. The reach begins above a culvert crossing under a private road as the stream leaves the rural residential land and enters timberland. Not far above the start of the reach, there is a recent timber harvest on the right hillslope which has recently been replanted. The first signs of spawning gravel appear below this point, but scoured to bedrock conditions become prevalent above where the recent timber harvest begins. As a result of the timber harvest, many of the remaining trees have blown down into the stream. About halfway through the reach, the stream passes over a 1.5m high step over concrete structure. The structure appears to have been constructed perhaps as a water diversion, as there are many pipes and hoses. This structure is a definite barrier to salmonids, as there is no jump pool present. The structure is trapping some nice spawning gravel above the step. About 150m above the concrete barrier, the stream passes through a culvert under a logging road and on to Longview Fibre Land. The upstream side of the culvert is plugged with debris, and it appears as though the stream flowed over the road during recent high flows during January. Above the culvert, the recent timber harvest ended on the right hillslope. Some pockets of spawning gravel were observed above the culvert, but most of the last hundred meters are scoured to bedrock. The survey ended at an ODFW Spawning Survey sign end point. Above the sign, the stream begins to be constrained by hillslopes and there is a significant reduction in the VWI, as well as an increase in gradient. There is good LWD project potential with a recent timber harvest on the right. Any future project should include the replacements of the barriers mentioned in reach 1 and the small concrete dam noted in reach 2. Overall, there are three fish passage barriers that may require future replacement activities in this survey. No planting project is necessary in the second reach with good shade cover even after a timber harvest on the right about halfway up the reach.

Above the culvert, the stream is constrained by a concrete wall on the left, which holds back a yard in front of the Johns\rquote house. The stream then passes over a s tep over concrete structure, which does have a nice jump pool below, but still passes as a potential artificial barrier. Not far above this structure the stream passes through a metal shotgun culvert under a private road on the Johns\rquote property. The culve rt on the left side is rusted through in some spots and is beginning to degrade. There is not much spawning gravel in this short reach, just pockets in the first riffle.

The first signs of spawning gravel appear below this point, but scoured to bedrock conditions become prevalent above where the recent timber harvest begins.

The structure appears to have been constructed perhaps as a water diversion, as there are many pipes and hoses. This structure is a definite barrier to salmonids, as there is no jump pool present. The structure is trapping some n i ce spawning gravel above the step. About 150m above the concrete barrier, the stream passes through a culvert under a logging road and on to Longview Fibre Land. The upstream side of the culvert is plugged with debris, and it appears as though the strea m flowed over the road during recent high flows during January. Above the culvert, the recent timber harvest ended on the right hillslope. Some pockets of spawning gravel were observed above the culvert, but most of the last hundred meters are scoured to bedrock. The survey ended at an ODFW Spawning Survey sign end point. Above the sign, the stream begins to be constrained by hillslopes and there is a significant reduction in the VWI, as well as an increase in gradient. \par }\pard \ql \li0\ri0\widctlpar\aspalpha\aspnum\faauto\adjustright\rin0\lin0\itap0 {\insrsid8325131 \par }\pard \ql \li0\ri0\widctlpar\aspalpha\aspnum\faauto\adjustright\rin0\lin0\itap0 {\insrsid8325131 There is good LWD project potent ial with a recent timber harvest on the right.
