This picture shows a surveyor on the North Fork Gualala River during habitat typing in 2001. The information provided by CDFG is that this is a backwater pool formed by a root wad. The pool was formerly the main channel but a four-foot high gravel bar formed and isolated it from the main flow. Photo provided courtesy of the California Department of Fish and Game, North Coast Watershed Assessment Program. CDFG information below: NF_HU.0103.01B Photo #25 07.31.01 64oF Backwater pool, root-wad formed [6.3] Embeddedness=1 Substrate=A Shelter value=3 Backwater pool was previously main channel. Pool is cut off from main channel by 4ft high gravel bar.

This picture shows a gravel bar on the North Fork Gualala River taken during habitat typing in 2001. The information provided by CDFG is that this is a low gradient riffle with a "sediment load on left bank." Small particle size distribution on the gravel bar suggests that it would be mobile on low frequency interval storms.

CDFG information below: NF_HU.0104 Photo #23 HU #0104 08.01.01 62oF H2O Low gradient riffle [1.1] Sediment load on Left bank N38o47.491' XW123o30.175'

This picture shows a deep pool on the North Fork Gualala River taken during habitat typing in 2001. The information provided by CDFG is that this is a lateral scour pool formed by a root wad with a maximum depth of 4.6 feet and that gravel embeddedness in its pool tail was below 25%. Photo provided courtesy of the California Department of Fish and Game, North Coast Watershed Assessment Program. CDFG information below: NF_HU.0124B Photo #21 HU #0124B 08.01.01 61.9oF H2O Lateral scour pool, root wad enhanced [5.3] Embeddedness=1 Substrate=C Shelter value=2 Root wad on Left bank 20ft X 12ft. Pool has 4.6 max 1.8ft mean 68ft long 21ft wide

This picture shows surveyor on a high gravel bar on the North Fork Gualala River taken during habitat typing in 2001. The information provided by CDFG is that this is adjacent to a low gradient riffle with an "unstable bank, five feet high." Small particle size distribution on the gravel bar suggests that it would be mobile on low frequency interval storms. Photo provided courtesy of the California Department of Fish and Game, North Coast Watershed Assessment Program. CDFG information below: NF_HU.0127.03 Photo #8 HU #0127 Unstable bank, 5oft high 08.11.01 63oF H2O Low gradient riffle [1.1] Shelter value=1

This picture shows small bank slip out adjacent to the North Fork Gualala River taken during habitat typing in 2001. The information provided by CDFG is that this is a mid channel pool with less than 25% embedded gravel at its pool tail. Photo provided courtesy of the California Department of Fish and Game, North Coast Watershed Assessment Program. CDFG information below: NF_HU.0566A Photo #16 HU #0566A 08.07.01 65oF H2O Mid-channel pool [4.2] Embeddedness=1 Substrate=D Shelter value=2 Landslide on right bank 20ft wide X 200ft high, 90ft from tail of pool.
