Potential Courses of Actions |
Funding Eligibility |
Priority |
A1 |
Reach 1 - Woodjam Creek, downstream of bridge on right bank (Lot 339) |
Point source sediment deposition from upland Stream bank erosion Cattle trampling of instream gravels |
- spiling: - wattling |
? |
1b |
A2 |
Reach 1 - Woodjam Creek ~50-100 m upstream of mouth on right bank. (L 2564) |
Same as for A1; riparian shrub community is wider here except adjacent to exposed soil areas |
- broadcast seeding
- spiling: - wattling: |
? |
1b |
A3 |
Entire length of Reach 1 Woodjam Creek |
Significant historical reduction in width of effective riparian shrub community Potential aggradation of channel |

A4 |
Entire length of reach 2 – Woodjam Creek (Lots 6317, 3779, 2565, 339) |
Significant historical reduction in width of effective riparian shrub community; Potential aggradation of channel |
|
? |
1a |
A5 |
Entire reach 3 – Woodjam Creek (Lot 6317) |
Significant channel widening and migration along entire reach (particularly downstream of prescription site C3) Channel aggradation appears to be occurring. Riparian vegetation has been significantly reduced by encroaching agricultural development and cattle grazing. Potential scour in steeper reaches upstream (10, 11, 12 and 14) may be contributing to aggradation of this and other reaches. |

R1 |
Deerhorn Road on west side of Woodjam in lower Reach 7 |
Chronic sediment delivery through cutblock and into Woodjam Creek. A sump has been has been installed downslope of road to trap sediment (further details can be obtained from Frank Kaempf – Riverside) |
|
Y? |
1a |
R2 |
Reach 1 – WSC 160-635400-29700-27400 adjacent to cutblock harvested 1994. |
Potential sediment source from road cutbank at switchback |
|
Y? |
1a |
R3 |
Reach 8 – Woodjam Creek Left bank |
Three locations adjacent to each other where potential run-off from the roads is delivering sediment to Woodjam Creek Highest potential for run-off is from steep spur road Culvert draining wetland may be undersized for transmitting wetland run-off |
|
N? |
1a |
C1 |
Reach 2 – Woodjam Creek (Lot 2565) |
Creek crossing structure is unknown Chronic sediment source may exist |
|
? |
2a |
C2 |
Reach 1 - ILP 001; |
Chronic sediment source at crossing directly downstream of reach break; impact is related to the crossing and/or upstream erosion from exposed soils |
|
? |
2b |
C3 |
Reach 3 – Woodjam Creek |
Potential chronic sediment delivery at this creek crossing; structure is unknown |
|
? |
2a |
C4 |
Reach 1 – Little Maclean Creek (WSC |
Crossing structure unknown; potential fish passage barrier Natural access further upstream may also be limited by series of small falls and low water levels. Low priority site unless chronic sediment source is observed |

C5 |
Reach 1 – WSC 160-635400-29700-25800 just upstream of mouth (Lot 9577). |
Creek crossing is likely a ford used by cattle and by lot owner to collect cattle Crossing may be a source of sediment. Chronic bank erosion may be occurring as a result of cattle trampling |
- spiling - watttling |
? |

C6 |
Reach 1 – Maclean Creek |
Potential sediment source at mouth of ILP 001 where a ford appears to provide agricultural vehicles and cattle access to either side of the creek. |
|
? |

H1 |
Reach 6 Woodjam Creek on east bank and two 1st-order tributaries within block |
Potential streambank integrity concerns and loss of riparian shading and woody debris recruitment |
|
N? |
3 |
H2 |
Reach 8 – Woodjam Creek |
Steep sideslope on west bank of Woodjam has potential to deliver sediment to stream, particularly if harvest-related blowdown occurs on the sideslope. Harvesting appears to have occurred right to the edge of the steep slope |
|
N? |
3 |
H3 |
Reaches 11, 12, 13 –Woodjam Creek on north and east banks |
Harvesting right to creek channel may have created bank instability problems; Removal of riparian vegetation has reduced shading and LWD recruitment
