Three reaches were designated based on: Land use and valley form. In the first reach Scour Pools (38%) and Riffles (46%) dominated the habitat, while Silt/organics (20%), Sand (44%), and Gravel (31%) were the dominant substrate types. In the second reach Scour pools (12%) and Riffles (84%) dominated the habitat, while Silt/organics (26%), Sand (50%), and Gravel (21%) were the dominant substrate types. Dammed and backwater pools (23%), Scour pools (25%), and Riffles (50%) dominated the habitat in the third reach, while Silt/organics (25%), Sand (46%), and Gravel (23%) were the dominant substrate types. The survey begins at the confluence of the Nehalem River near the Vernonia Airport. An ODFW Spawning Survey sign was not noted at the start point. Beaver activity was observed throughout the survey, which improved the complexity. However, there is good potential for future LWD projects in reaches 1 and 2. REACH DESCRIPTIONS: REACH 1: Length 370 meters. The channel is constrained by terraces in a broad valley. The average valley width index is 4. Land use for the reach is second growth timber. The average unit gradient is 1.5%. The channel characteristics include: primary 370m and secondary 6m. Two pools were greater than 1 meter deep, which averages to 5.4 deep pools per 1 kilometer of primary stream length. There were three key pieces of LWD which averages to 0.8 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 conifers and deciduous ranging from 15 30 cm dbh, with some deciduous 3 15 cm dbh. This survey begins at the confluence with the Nehalem River. The first hundred meters of the stream is influenced by the Nehalem River during high flows. There is an old culvert that has been left in the creek at a very old road crossing about a hundred meters up from the start of the survey. At this point, there is also a major elk crossing as well as what appears to be ATV tracks on the old road. There were a number of blown out beaver dams in this reach, although a few had new activity and fresh cut sticks. There were some pockets of decent spawning gravel. There was a lack of secondary channels in this reach, with the only off channel habitat comprised of a few backwaters and an isolated pool. The riparian was also marginal in this reach, with a number of small alders. Reach 1 ends as the stream becomes constrained by hillslopes. There is good LWD project potential with fair access for industrial equipment. The ATV recreational usage, is not impacting the stream, the surveyors observed tracks on the terraces and should be controlled if any future project is planning. The riparian has small conifers. So, a planting project is not necessary. REACH 2: Length 462 meters. The channel is constrained by hillslopes in a narrow valley. The average valley width index is 2.5. Land use for the reach is large timber. The average unit gradient is 1.3%. The channel characteristics include: primary 462m and secondary 32m. One pool was greater than 1 meter deep which averages to 2.2 pools per kilometer of primary stream length. There were eight key pieces of LWD, which averages to 1.7 key pieces per 100m of primary channel. The vegetation is based on 1 riparian transect. The trees found most frequently in the riparian zone were mostly mixed sizes of conifers and deciduous ranging from 30 - 50 cm dbh, with some mixed conifers and deciduous 3 15 cm dbh. Reach 2 begins as the valley width index becomes less than 2.5. The riparian improves in this reach, although devils club begins to become predominant. The amount of spawning gravel diminishes in this reach with only a few good pockets. There continues to be a lack of off channel habitat. A few coho were observed in the stream margins and in a few backwaters. As in Reach 1, there were a number of blown out beaver dams observed throughout the reach. Reach 2 ends at an old decommissioned road crossing with an old culvert still left buried in the stream margin. Below this old road crossing there was a 0.9m high step over log, with a blown dam (fresh chew sticks), that had no jump pool. This was observed to be a potential barrier for salmonids. There is good LWD project potential with good access for industrial equipment. There is not much complexity in this reach and any future project with LWD would be beneficial. The riparian has small and medium sized conifers. So, a planting project is not necessary. REACH 3: Length 514 meters. The channel is constrained by hillslopes in a narrow valley. The average valley width index is 1.8. Land use for the reach is large timber, a sub dominant land use was observed to be young timber. The average unit gradient is 2.0%. The channel characteristics include: primary 514m and secondary 7m. One pool was greater than 1 meter deep, which averages to 1.9 pools per kilometer of primary stream length. There were twenty-one key pieces of LWD, which averages to 4.1 key pieces per 100m of primary stream channel. The vegetation is based on 2 riparian transects. The trees found most frequently in the riparian zone were mostly mixed sizes of conifers and deciduous ranging from 30 - 50 cm dbh, with some mixed conifers and deciduous 3 15 cm dbh. Reach 3 begins at an old road crossing where there is a change in land use. The reach continues to be constrained by hillslopes. Not far from the beginning of the reach, there is a more recent timber harvest, which has been replanted. The amount of devils club increases in this reach with some large patches throughout. Partially blown beaver dams were also present throughout. Within the last 200m of the survey the habitat becomes marginal due to numerous spring seeps. The survey ends due to a lack of flow at this point. Above the end point the gradient increases and the VWI becomes 1. There continues to be cutthroat habitat for another 200-500m. There was a high amount of key pieces in the reach so a LWD project is not necessary. The riparian has a nice mixture of conifers and deciduous so, a planting project is not necessary. ; 1  !!!!H"P"hkmhRhl5CJ\hl,:;MNmn% F G _ ` u v I J !!!!!!!!!!!!!!!!!!!!!!! !!!!!$a$gdCP" cd!!I"J"L"M"P"!!! !! !!!!!! !! !!!!!! !!!!!!!!!Ole 5OlePres000, ITEM000ODS ITEM000FMT#3 FP?ŴDP?ŴD;lX   ."System8$r0E -@Times New Roman-  2 Z -@Times New Roman-J2 e*Upper Nehalem Watershed Habitat AssessmentTAA44T4A:!4`u;'44.A3A[;@!&;'T--4..`4A' 2  >2 e Stream ReportA'44;`T4A;4' 2 e{ > 2  ?-#2 _STREAM: Weed Cr8=C=HY_,,2C! 2 _J : 2 _ - 2  -82 ESUBBASIN: Upper Nehalem River8HBBH9 HH22,!H,3,,NC2,! 2 E . 2  -.2 +DATES: March 21, 2006HH==8Y,!,2222232 2 +% - 2  -L2 +SURVEY CREW: Todd Boswell, Mark McLaughlin8HCH=HCC=_=221B2'H,Y,!2Z-<,3222 2 ^ - 2  -;2  REPORT PREPARED BY: Ben WalczakC=8HC=8C<8HC=HBHB,2_,,-,2 2  . 2 j -/2 GENE CONSERVATION GROUP:H=H=CHH8=CHH> IHHCHH8 2  ' 2 12 2 -!2 /NCHC 2  - 2 P -2  UTM COORDINH=YCHHCI H2 ATES:hH==8 2  2 Start 8,! 2 2.2  0480307 E & 5076506 N 2222222=M2232222H 2   - 2 6 , 2 6, , 2 6X , 2 6 ,2 6End =22 2 6j2.2 6 0478686 E & 5076235 N 2222222=M2232222H 2 6  - 2  -.2  USGS MAPS: Clear CreekH8H8YH88B,,!C!-,2 2  W - 2  -)2  GENERAL DESCRIPTION:H=H=CI<H=8CD8>!HH 2   - 2 u  - 2  ,2 ,OThe Weed Creek winter habitat survey begins at its confluence with the Nehalem =2,_,,2C!,,2H2,!2,2,'2!2.02-12',',22!2,2,,H22,H-2,,N@2 [ #River and extends 1,346 meters.

The reach continues to be constrained by hillslopes. Not far from the beginning of the reach, there is a more recent timber harvest, which has been replanted. The amount of devil s club increases in this reach with some large patches throughout. Partially blown beaver dams were also present throughout. Within the last 200m of the survey the habitat becomes marginal due to numerous spring seeps. The survey ends due to a lack of f low at this point. Above the end point the gradient increases and the VWI becomes 1.
