Regional Board Conclusion: DELIST REFERENCE STREAMS:
The following streams are being proposed for delisting from the section 303(d) list for Temperature under section 4.11 of the Listing Policy: (a) Wooley Creek and its tributaries from the head waters to the confluence with the North Fork Wooley Creek (LOE 31582); (b) Wooley Creek and its Tributaries from the confluence of the North Fork Wooley Creek to Haypress Creek (except North Fork Wooley Creek and its tributaries) (LOE 31581); (c) North Fork Wooley Creek and its Tributaries (LOE 31580).

The streams listed above are temperature reference water bodies. Temperature reference water bodies are not significantly altered by anthropogenic activities and therefore, temperature conditions in these water bodies reflect natural conditions.

Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for removing (a) Wooley Creek and its tributaries from the head waters to the confluence with the North Fork Wooley Creek, (b) Wooley Creek and its Tributaries from the confluence of the North Fork Wooley Creek to Haypress Creek (except North Fork Wooley Creek and its tributaries), (c) North Fork Wooley Creek and its Tributaries from the section 303(d) list for temperature. This conclusion is based on the staff findings that: (1) The data used satisfy the data quality requirements of section 6.1.4 of the Policy. (2) The streams listed above meet the criteria for reference water bodies and are not significantly altered by anthropogenic activities and therefore, temperature conditions in these water bodies reflect natural conditions, which indicates attainment of the temperature water quality objective. (3) This process is scientifically defensible and reproducible.

DO NOT DELIST NON-REFERENCE STREAMS:
The remainder of this water body (non-reference streams) is being considered for removal from the section 303(d) list for temperature under section 4.11 of the Listing Policy.

Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing the non-reference streams from the section 303(d) list for temperature (i.e., sufficient justification to not delist). This conclusion is based on the staff findings that: (1) The data used satisfies the data quality requirements of section 6.1.4 of the Policy. (2) Ten of 10 MWMTs from the non-reference portion of Wooley Creek (LOE 31596) exceed the evaluation guideline. (3) 303(d) listing determinations made prior to 2006 were not held in an assessment database. LOE 25802 is a placeholder for the 303(d) listing data and information for all streams in this water body from a previous assessment cycle that was initially utilized to make this listing determination. (4) This process is scientifically defensible and reproducible.
 
Regional Board Decision Recommendation: This region was not assessed this cycle. All decisions have been carried over from the previous cycle and remain the same.
 
State Board Review of Regional Board Conclusion and Recommendation:
 
State Board Decision Recommendation: After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Evaluation Guideline: EVIDENCE OF NATURAL RECEIVING WATER TEMPERATURE: The Klamath River HU, Salmon River HA, Wooley Creek HSA, Wooley Creek and its Tributaries from the confluence of the North Fork to Haypress Creek (except North Fork Wooley Creek and its tributaries) water body has been identified as a temperature reference water body in the "Klamath National Forest Sediment and Temperature Monitoring Plan and Quality Assurance Project Plan" (USFS 2010). Klamath National Forest (KNF) staff followed the State of California's Surface Water Ambient Monitoring Program guidance for screening and identifying reference water bodies (Ode 2009). Regional Water Board staff at the North Coast Region reviewed and approved the criteria that were developed by the KNF to identify temperature reference water bodies. Temperature reference water bodies must meet the following criteria: 1) no evidence of human-caused reduction in stream shade is apparent in aerial photos, 2) road density must be less than 0.19 km/km squared (0.30 mi/mi squared) with no significant failures (this road density value also signifies low past timber harvest intensity), 3) less than 10% of the drainage area is grazed and there are no best management practice violations, and 4) mining activities have no significant sediment inputs. Water bodies with natural disturbance were included in the reference pool as a component of the natural variability in conditions. The Klamath River HU, Salmon River HA, Wooley Creek HSA, Wooley Creek and its Tributaries from the confluence of the North Fork to Haypress Creek (except North Fork Wooley Creek and its tributaries) water body meets the criteria for temperature reference water bodies, and thus, temperature conditions in this water body reflect natural conditions.

Evaluation Guideline: According to the Salmon River TMDL (NCRWQCB 2005), stream temperatures in this water body have been altered by changes in riparian cover, increased solar heating, and changes in streamside microclimates. If the natural receiving water temperature has been altered, or if alternation is unknown, the evaluation guideline to determine adverse affect on the most sensitive beneficial use (in this case, salmonids) is as follows. Per "U.S. EPA Region 10 Guidance for Pacific Northwest State and Tribal Temperature Water Quality Standards" (USEPA 2003), the U.S. EPA recommends a criterion for the protection of moderate to high density summertime salmon and trout juvenile rearing (i.e., core juvenile rearing) of a maximum weekly maximum temperature (MWMT) of 16 degrees C. The MWMT is also known as the maximum 7-day average of daily maximums (7DADM). The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities.

Objective/Criterion Reference: Water Quality Control Plan (Basin Plan) - North Coast Region (Region 1)
 
Evaluation Guideline: The density of roads within a watershed can impact water temperature and alter natural conditions. Near-stream roads that run parallel to a waterbody do not allow for vegetation to grow and produce shade. Roads are also a major source of erosion and sedimentation on most managed forest lands. Excess sediment in the stream channel can result in higher water temperatures as pools fill in with sediment and channels widen in response to the increased load. Per NOAA Fisheries (1996), the guideline for the properly functioning condition for road density and location is less than 2 miles of road per square mile of watershed with no valley bottom roads.

Spatial Representation: Road density and location information were assessed for the entire Wooley Creek Hydrologic Sub-Area.
Temporal Representation: The road density data from the Klamath National Forest are based on data collected following the 2006 wildfires for the 2007 model year. The road location data used for the Salmon River TMDL was collected in 1993.
Environmental Conditions: The road density data from the Klamath National Forest are based on data collected following the 2006 wildfires for the 2007 model year. There are no known environmental conditions (e.g., seasonality, land use practices, fire events, storms, etc.) that are related to the data from the Salmon River TMDL.
QAPP Information: Road density data from the Klamath National Forest were developed as part of the Equivalent Roaded Area (ERA) model conducted by staff of the Klamath National Forest in accordance with the procedures described by Elder and Reichert (2004). The Salmon River TMDL is of sufficient quality per Section 6.1.4 of the 303(d) Listing Policy. It describes temperature conditions and their impacts on water quality, provides linkages between the TMDL and the temperature water quality standard, is scientifically defensible, was developed by qualified professionals, was scientifically peer reviewed, and was adopted by the Regional Water Board.

Data Used to Assess Water Quality: Much less than 15% of the Wooley Creek watershed has been or is currently disturbed by human activities. Per the Klamath National Forest (KNF 2001, Attachment F), 95% of the Wooley Creek watershed is a congressionally designated Wilderness Area. An additional 3% of the lands are managed as late-successional reserves, which limits management activities to those which promote old-growth habitat. Less than 1% of the watershed is privately owned.

SWAMP Data: Non-SWAMP
 
Water Quality Objective/Criterion: Per the Basin Plan (NCRWQCB 2007): The natural receiving water temperature of intrastate waters shall not be altered unless it can be demonstrated to the satisfaction of the Regional Water Board that such alteration in temperature does not adversely affect beneficial uses. At no time or place shall the temperature of any COLD water be increased by more than 5 F above natural receiving water temperature.
Objective/Criterion Reference: Water Quality Control Plan (Basin Plan) - North Coast Region (Region 1)
 
Evaluation Guideline: Human disturbance within a watershed can impact water temperature and alter natural conditions. Activities that remove or reduce shade-producing vegetation, or that result in a discharge of sediment to a stream, can increase stream temperatures. Per NOAA Fisheries (1996), the guideline for the properly functioning condition for disturbance history is for the entire watershed to be less than 15% disturbed with no concentration of disturbance in (1) unstable areas, (2) potentially unstable areas, (3) refugia, and/or (4) riparian areas. For areas under the Northwest Forest Plan (which includes the Wooley Creek watershed), the guideline for the properly functioning condition for disturbance history is also for there to 15% retention of late succession and old growth forest in the watershed.

Impairment from Pollutant or Pollution: Pollutant
 
Regional Board Conclusion: This pollutant is being considered for placement on the section 303(d) list under section 3.11 of the Listing Policy. Three lines of evidence are available in the administrative record to assess this pollutant.

Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category (i.e., sufficient justification to not list ). This conclusion is based on the staff findings that: (1) The data used satisfies the data quality requirements of section 6.1.4 of the Policy. (2) The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. (3) The following streams are not significantly altered by anthropogenic activities and therefore, sediment conditions in these water bodies reflect natural conditions: (a) Wooley Creek and its tributaries from the head waters to the confluence with the North Fork of Wooley Creek (LOE 31582); (b) Wooley Creek and its Tributaries from the confluence of the North Fork of Wooley Creek to Haypress Creek (except North Fork Wooley Creek and its tributaries) (LOE 31581); and (c) North Fork Wooley Creek and its Tributaries (LOE 31580). (4) Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met.

Evaluation Guideline: Evidence of anthropogenic alterations to sediment conditions was assessed to determine compliance with the sediment water quality objectives. Sediment reference water bodies must meet the following criteria: 1) road density must be less than 0.19 km/km squared (0.30 mi/mi squared) with no significant failures (this road density value also signifies low past timber harvest intensity), 2) less than 10% of the drainage area is grazed and there are no Best Management Practices violations, and 3) mining activities have no significant sediment inputs. Water bodies with natural disturbance were included in the reference pool as a component of the natural variability in conditions.

Sediment conditions in the Klamath River HU, Salmon River HA, Wooley Creek HSA, Wooley Creek and its Tributaries from the confluence of the North Fork to Haypress Creek (except North Fork Wooley Creek and its tributaries) water body meet these criteria, reflect natural conditions, and are not significantly altered by anthropogenic activities as documented in the "Klamath National Forest Sediment and Temperature Monitoring Plan and Quality Assurance Project Plan" (USFS 2010). Klamath National Forest (KNF) staff followed the State of California's Surface Water Ambient Monitoring Program guidance for screening and identifying reference water bodies (Ode 2009). Regional Water Board staff at the North Coast Region reviewed and approved the criteria that were developed by the KNF to identify sediment reference water bodies.
