Cloquallum Sub-Basin  (Facts and Maps)

These are the restoration, preservation, and data gap actions recommended by the Limiting Factors TAG.

The actions have been prioritized based upon the Limiting Factors Report coupled with professional judgment.

Limiting Factor

LF Rating

Restoration Actions

Preservation Actions

Data Gap Actions

Fish Passage

DG. Road density is high (4.5 mi/sq mi).

H - Open three or more miles of good quality habitat used by at least one stock of salmon or steelhead.  Exceptions:  include very cost efficient projects addressing unique limiting habitat or benefiting multiple stocks of salmon or steelhead.

 

H - Bridges are the preferred structure.  If culverts are used, they should be sized to allow full access to all fish species and life history stages.

H – Prevent removal of appropriate pieces of LWD, and other natural structures, within the floodplain through increased education and enforcement. 

H - Inventory, assess, and prioritize all habitat blockages (culverts, dikes, railroad grades, etc.) for all salmonid life history stages. 

 

H - Develop a database housed with the lead entity, to contain all blockage data. 

 

 

Floodplain Conditions

 

Poor (DG). Known problems include rip-rap, channel incision, and roads.

 

H - Reconnect potential off-channel habitat. 

 

H – Reduce bank armoring.

 

H - Restoration actions need to increase instream LWD to help address channel incision and flow issues.  This includes appropriate riparian restoration to result in better future LWD levels.

 

H – Maintain, conserve, and prioritize off-channel and side-channel habitat and associated riparian. 

 

H - Develop and enforce Critical Areas Ordinances. 

H - Inventory impacts and suitable restoration sites for floodplain habitat coincident with the barrier/culvert inventory.

 

 

Sediment

 

Poor (DG). Known problems are high road density, bank erosion, logging impacts, livestock access.

H – Correct high impact road sediment delivery problems via push-outs, cross-drains, and sediment traps etc.

 

L - Provide education regarding the impacts of vehicle activity in streams and increase enforcement.

 

M - Provide education regarding the impacts of livestock.

 

H - Reduce livestock access to Cloquallum River.

 

H - Reduce roads and logging activities in sensitive areas near stream.

 

H. Allow forestlands to regenerate as per new forest practice regulations. 

H - Inventory roads and assess impacts to salmonids and prioritize restoration actions accordingly. 

 

H - Assess bank failures, bulkhead and channel confinement, and riparian conditions, and prioritize restoration actions accordingly.

LWD

DG. High peak flows, loss of riparian, channel incision.

 

H - Actions are needed to increase LWD, or similarly functioning natural structures, in appropriate places.  This would include anchoring LWD and increasing natural recruitment potential (riparian restoration).

 

H – Prevent removal of appropriate pieces of LWD, and other natural structures, within the floodplain through increased education and enforcement. 

 

H - Allow forestlands to regenerate as per new forest practice regulations.  

 

H - Determine appropriateness through inventory or other assessment of LWD, or other natural structure(s), placement.  (e.g. gravel recruiting,  hydrology, wood or structure size, gradient, near term LWD recruitment potential, and valley confinement).

 

H - Assess to determine size, amount, and location or needed LWD.

 

Riparian

Poor

H - Revegetate open riparian areas with native plants including conifers in appropriate places.

 

M - Interplant conifer into hardwood riparian areas that were historically conifer areas.   

 

M- Plant conifer adjacent to and outside existing and limited existing conifer hardwood riparian areas.

 

H - Fence and revegetation where needed.

 

L – Address human-caused bank erosion in a fish-friendly manner, where protection of private property is desired.

H - Funds, lands, and easement opportunities should be identified to obtain areas of mid-to late seral stage riparian with priority given to older stands.  This is applicable to lands that do not have current protection such as those outside of current forest practice regulations.

 

H – Continue enforcement and revision of current regulations that preserve and enhance riparian regeneration.

H - Assess and prioritize recovery and protection for riparian conditions.

 

 

Water Quality

DG (Known Poor in Wildcat). Warm water temps in Wildcat. Poor riparian throughout. Livestock access a problem.

H - Actions need to address sediment, riparian, and flow problems. 

 

H - Reduce livestock access to Cloquallum River.

 

 

H - Increase activities that lead to natural recharge of the aquifers and maintain or improve hydrological maturity. 

 

H - Restore wetlands and off-channel habitat.

 

H – Reduce sediment inputs from roads.

 

H – Reduce waste inputs (livestock and urban).

 

H - Decrease activities that interfere with the natural recharge of aquifers or degrade hydrological maturity.

 

 

 

H - Monitor water temperature, dissolved oxygen, pH, and turbidity.

Water Quantity

Poor (DG). Poor hydrologic maturity and Wildcat Creek is a "closed" stream.

H - Reduce water withdrawals from surface sources.

 

H - Increase activities that lead to natural recharge of the aquifers and maintain or improve hydrologic maturity. 

 

H -Restore wetlands and off-channel habitat.

H - Decrease activities that interfere with the natural recharge of aquifers or degrade hydrological maturity.

 

 

H - Install stream flow gage and assess summer low flows, documenting human impacts.

 

Biological Processes

 

DG

L - Increase contribution of marine –derived nutrients through increased use of carcasses.

 

 

 

H - Increase field surveys regarding salmonid distribution, escapement, and habitat use by life history stage.

 

L - Assess marine-derived nutrient processes.
