EXECUTIVE SUMMARY

R-6 Stream Survey Level II

LAKE CREEK
Gifford Pinchot National Forest
Randle / Packwood Ranger Districts

INTRODUCTION:

The purpose of the executive summary is to highlight key attributes and issues for the Lake Creek basin. The stream from the confluence to Packwood Lake dam was surveyed and analyzed during the 1993 summer season. Below is a discussion of the stream attributes graphed on the accompanying pages, an explanation of the issues, and management recommendations for the basin. These attributes or elements were picked by the Forest as indicators for the Desired Future Condition (DEC) as outlined in COLUMBIA RIVER BASIN Anadromous Fish Habitat Management Policy and Implementation Guide (PIG).

DESCRIPTION:

* Lake Creek on Packwood Ranger District, drains into the Cowlitz River, the confluence is in section 11, T.13 N., R. 9 E..

* Lake Creek is a main-stem stream in Lake Watershed #2524, as delineated on GIS PIG mapping dated 1/6/93.

* Lake watershed totals 24320 acres, most of which are within National Forest boundary (the first 0.7 miles is on private lands).

* A Region 6 Level II survey was completed on 5.4 miles of Lake Creek, section below Packwood dam.

* Lake creek has 1.9 miles of anadromous habitat (coho, Oncorhynchus kisutch, chinook, Oncorhynchus tshawytscha and steelhead, Oncorhynchus mykiss) and 5.4 miles of resident trout habitat (rainbow trout, Oncorhynchus mykiss).

* The lower Lake Creek system has 11 falls, 23 chutes, 2 bridges and 1 dam.

* Washington State Fisheries and Bonneville Power Administration have started the reintroducing of anadromous fish into the Cowlitz River basin, Lake Creek flows into the Cowlitz River.

* Coho, summer chinook, and winter steelhead will use Lake Creek for spawning and rearing.

ISSUES:

* Human activities in the basin started during the early I950's with the start of timber harvesting and continued into the 1980's.

* Approximately 30% of the riparian buffers have been harvested.

* Forest Road #1262 parallels Lake Creek for the 2.8 miles.

* Forest Road #1266041 parallels Lake Creek 2 miles.

* Lake Watershed is part of the Reserve Areas as defined in the Forest Ecosystem Management: An Ecological, Economic, and Social Assessment (FEMAT report).

MANAGEMENT RECOMMENDATIONS:

Priority One:

- Conduct watershed inventories to identify temporary roads, roads drainage systems and high-erosion areas which are contributing sediment to the stream channel.

- Prioritize projects (road closures, bank stabilization, in-stream structures, etc.) to begin restoring these areas and request watershed, fisheries, and engineering money to repair and revegetate.

Priority Two:

- Diversify Habitat:

- Place large wood material in the lower 4 miles of the stream to create more habitat complexity.

- Utilize large wood pieces longer than twice the bankful width and a mix of small and large boulders to create this complexity. Use these materials to stabilize streambanks by placing them at high profiles on the banks.

Priority Three:

- Educational Opportunity:

- Work with the land developer of the Goat Rocks development for educational projects, such as in-stream structures, bank stabilization projects, and field talks.

EXPLANATION OF GRAPHS:

The GOOD range shown on each of the graphs represent the desired future condition of each stream attribute. Specifics about the DFC's are elaborated upon in the body of the stream survey report.

Graph 1, Temperature:

- Stream temperatures were measured during the survey of Lake Creek, three times a day for each day on the stream, with pocket thermometers. The temperature graph shows these results. Salmonids thrive in streams with water temperatures between 55° F and 65° F.

- Lake Creek is within the limits for “GOOD” water temperature. This means that water temperatures were “below or equal to” optimum for salmonids. The section just below the Packwood dam (Reach 6) had the highest water temperature at 64° F. This is getting close to being outside the recommended temperature range. By Reach 5 the water temperature is down to 58° F and by Reach 1 the water temperature is 53.6°F.

Graph 2, Large Woody Materials:

- Large wood is important for stream structure and habitat complexity, sediment storage, bank protection and for delivery of photosynthesized products to the aquatic environment.

- The overall rating for Lake Creek is POOR, because 100% of the stream has less then the desired 80 pieces/mile of LWD.

Graph 3, Width to Depth Ratio:

- Width to depth ratio is a measure of the channel cross-section. Ratios which exceed 10 indicate a stream channel that is wide and shallow, generally contains few features and is aggrading from sediment input.

- All of the reaches exceed the threshold of 10.

- Overall rating is POOR.

Graph 4, Pool : Riffle : Glide Ratio:

- Healthy streams of similar geomorphology approach a 40 : 60 ratio of pools and riffles with the presence of flow dissipating elements in the stream channel. These features include large wood, small and large boulders, bedrock areas, and side channel areas.

- Lake creek is rated POOR because all the reaches fall below the recommended 40 : 60 ratio.

Graph 5, Watershed Rating:

- Lake Creek rates POOR or low risk because of the low road density in the basin - 1.75 miles / square mile and 23% of the watershed is in timber stands of less then 30 years. The basin's geology requires careful consideration of where activities take place. Headwall areas or sensitive stream channels can cause exponential impacts to the stream if not managed properly.

BASIN OVERVIEW

INTRODUCTION

A stream survey was conducted on the lower section of Lake Creek (from the dam down) during the summer of 1993. This is the second survey (on lower Lake Creek) that the Packwood district has done to date. The stream survey was conducted from the confluence of Lake Creek and Cowlitz River, section 11, T. 13 N., R. 9 E. to Packwood Lake dam in section 21, T. 13 N. R. 10 E. This portion of the stream surveyed passes through 4.7 miles of National Forest lands and 0.7 miles of private lands. Lake Creek was surveyed to assess the riparian habitat and aquatic habitat. The stream section surveyed was broken into 6 reaches.

HISTORY

Forest Service management in the Lake Creek basin started in 1905 with the construction of a trail into Packwood Lake. Timber harvesting and road construction followed 47 years later with the first timber harvest unit just inside the Forest Boundary in 1952. Timber harvesting and road construction continued into the 1980's. In 1962 Tacoma City Light started construction of Packwood Dam (hydroelectric) at the out-let of Packwood Lake on Lake Creek. The dam was finished and in production in 1964. In June 1990 the Land and Resource Management Plan for the Gifford Pinchot National Forest was signed. In 1991 the entire basin was changed to a Habitat Conservation Area (HCA) which stopped all timber harvesting in this basin. In 1993 the allocation for the basin is again proposed for change, under Option 9, now to a mix of Riparian Reserves (designated riparian areas found outside the Late-Successional Reserve, no timber harvesting) and Late-Successional Reserve (a forest in its mature and/or old-growth stages, no timber harvesting). The upper basin, from Packwood Lake to the headwall, was part of the “wild area” classification of the 1930's. In 1964 this "wild area" was reclassified to Goat Rocks Wilderness. In 1984 this area was enlarged to include the land on either side of Packwood Lake on both Snyder Mountain and Coal Creek Mountain.

~ Trailhead into Packwood Lake and Goat Rocks Wilderness.

TIMBER.

~ Basin wide timber harvesting has been going on since the early 1950's.

~ The smaller streams within harvest units do not have timbered buffers.

~ Twenty-three (23%) of the lower basin has plantations less then 30 years.

~ Reach 5: Stream gradient change to a change in valley type change, 1.8 miles

~ Reach 6: Valley type change to gauging station below dam, 0.5 mile

DESIRED FUTURE CONDITION

~ Stream temperature between 45° F and 65° F.

~ Eighty (80) pieces of large wood size class material per mile, 36 inches DBH and at least 50 ft. long.

~ Pool/riffle ratio approaching 40:60 ratio.

~ Width to depth ratio less than 10.

~ Fifty-six (56) pools per mile. (this number is based on the wetted width of the stream .... in the case of Lake creek the average wetted width is 20 feet, from the paper on smolt production, a stream with a 20 foot wetted width should have 56 pools/mile).

~ Fisheries include a viable population of anadromous and resident species.

~ Watershed vegetation composed of conifer stands 35 years or older in 75% of basin area,

~ Riparian vegetation 0 to 100 feet from edge of stream would be a mix of 85% conifer and 15% hardwood component in a mature age class.

~ Areas of low gradients would have side channels present.

~ Channels with gradients of less than 2% would be less entrenched.

~ Substrate would be gravel / cobble mixture intermixed with small boulders.

~ Road density of less than 2.0 miles per square mile.

EXISTING CONDITION

~ Stream temperatures range from 50° F to 64° F.

~ Large Woody Debris (LWD) is lacking in all reaches (Graph 2, Executive Summary).

~ Pool/riffle ratio is less than the recommanded 40:60 ratio (Graph 4, Executive Summary).

~ Width to depth ratio for all of Lake Creek excess the threshold limits (Graph 3, Executive Summary).

~ Pools per mile range from a minimum 28.9 (Reach 3) to a maximum of 44.0 (Reach 6). The average for the whole stream is 37.1.

~ Effective cover is generally good.

~ Banks are in fair condition with few exception.

~ The riparian vegetation consists of 87% conifers and 13% hardwoods.

~ Road density is less than 2.0 miles per square mile (1.75mi/sq.mi).

~ Timber sales and the practice of removing wood from the streams in the late '70's and early '80's have caused a deficiency of Large Woody Debris (LWD).

~ The percentage of the basin in timber stands less then 30 years is 23%.

~ The aggregated recovery percentage (ARP)² for the Lake Watershed is 85.3 percent.

Riparian Conditions:

Timber / Roads:

Much of the timber harvesting and road construction has already taken place. Many of the Class III's and VI's in the lower part of the basin have been cut over. Lake Creek has a timber buffer of mature timber for the entire length of stream on National Forest lands.

² The ARP is an indicator of how well the watershed can absorb a rain-on-snow event. The rating is from 100% down. The lower the number the more damage a watershed can be expected to recieve during a rain-on-snow event. The Gifford Pinchot National Forest uses a threshold of 70%.

Recreation:

The basin has some use by big game hunters, (elk, deer and bear) and some light fishing activity. There are no known camping sites in lower Lake Creek. The upper basin is in Goat Rocks Wilderness and one of the trailhead (trail #78) is located at the end of Forest Road #4830066.

Fish Habitat, PIG:

Overall Lake Creek is in poor condition for fish use. Using measured items like pools/mile, bankfull width to depth ratio, and pool/riffle ration the lower reaches are not functioning as they should. The existing Smolt Habitat Capability (SHC) for lower Lake Creek are; coho - 551, chinook - 272, and steelhead - 37. The projected SHC are; coho - 4468, chinook - 9418, and steelhead – 1030.

MANAGEMENT RECOMMENDATIONS

Priority One:

Conduct watershed inventories to identify temporary roads, roads drainage systems and high-erosion areas which are contributing sediment to the stream channel.

Prioritized projects (road closures, bank stabilization, in-stream structures, ect.) to begin restoring these areas and request watershed, fisheries and engineering money to repair and revegetate.

Priority Two:

Diversify Habitat:

Place large wood material in the stream to create more habitat complexity.

Utilize large wood pieces longer than twice the bankful width and a mix of small and large boulders to create this complexity. Use these materials to stabilize streambanks by placing them at high profiles on the banks.

LAKE CREEK
Gifford Pinchot National Forest
Packwood Ranger District

REACH SUMMARY

A stream survey was conducted on Lake Creek during the summer of 1993. This is the second survey that the Packwood district has done to date. Lake creek was broken into 6 reaches. Lake creek is relatively steep (average gradient of 7%) and some portions are contained within a bedrock canyon. None of the stream was classified as inaccessible. The majority of the valley type is moderate to steeply incised. Road access was used to reach the creek. The mouth of the creek lies approximately 2 miles north of Packwood via State Highway 12. The first reach is on private lands and is boundary by managed timber land on the north and a housing development on the south. On the forest, Lake creek can be access by Forest Roads 1260022, 1262022, 1262000 (on the south) and Forest Road 1266041 (on the north). The flow is controlled for the production of hydroelectric power at the outlet of Packwood Lake.

REACH 1

Reach 1 starts at the confluence with the Cowlitz River and extends up to where the valley become bedrock vertical walls, a distance of 0.7 mile (NSO #0 - 50). The valley type is classified as a trough-like open short slope length valley. Private lands boarders this reach for the full distance. Reach 1 contains two road crossings, State Highway 12 (NSO #16) and Lake Creek Road (NSO #25). Both crossings are cement bridges.

SMART DATA:
Stream Gradient: 3%	Pools/Mile: 37.1
Bankful Width: 10.81	LWD/Mile: 0.0
Substrate: Small Boulder/Cobble	Riparian Vegetation: ST Alder
Temperature: 52° F	Fish Species: rainbow trout

MANAGEMENT CONCERNS:

1) Lack of LWD
2) Lack of pool habitat
3) Residential development

REACH 2

Reach 2 starts at the bedrock vertical wall, from a trough-like open short slope length to a box-like canyon and extends for 0.6 miles to a valley change, narrow V-shaped floor (NSO #51 - 106). The gradient for this reach averages 10 percent and has a gradient of as much as 16 percent. There are at least two bedrock gorges contained in this reach. The first falls is located approximately 0.9 mile from the confluence and is 4 feet in height (NSO #64).

ROADS / TIMBER:

Forest Road 2261022 and 2262022 parallel Lake Creek in this reach. There has been some timber harvest activities on both sides of the stream in this reach. A 200 to 300 foot buffer of old-growth timber was left for the entire length of reach 2. Most of the riparian zone is made up of douglas fir in the small tree class.

RECREATION:

Recreation use of reach 2 is moderate. There are a couple of dispersed camp sites off of Forest Road 2261022, and there are signs of light fishing pressure.

SMART DATA:
Stream Gradient: 10%	Pools/Mile: 40.0
Bankful Width: 15.63	LWD/Mile: 6.3
Substrate: Small Boulder/Large Boulder	Riparian Vegetation: ST Douglas Fir
Temperature: 54° F	Fish Species: rainbow trout

MANAGEMENT CONCERNS:

1) Lack of large wood
2) Lack of pools

REACH 3

Reach 3 starts where stream leaves bedrock controlled channel (gorge), and ends at a 25 foot high falls, a distance of 0.9 mile (NSO #107 - 172). This reach is still in a narrow V-shaped valley. The stream gradient reaches as high as 22% in a section of stream (NSO #163) There is some beaver activity.

ROADS / TIMBER:

Forest Road 1262022 and 1266041 parallels reach 3. Although these roads are not next to the stream they were used to harvest timber from the riparian zone of Lake Creek. The plantations appear to well stocked and the buffers adequate but would not meet Option 9 standards (less then 300 ft.).

RECREATION:

This reach is not easy to access from any direction. Either Forest Road 2262022 or 2266041 will get a recreationist “close”. However, they still have to hike across country down some very steep slopes to reach the stream. Due to the ruggedness of the terrain few people use the area.

SMART DATA:
Stream Gradient: 8%	Pools/Mile: 28.9
Bankful Width: 17.62	LWD/Mile: 9.2
Substrate: Small Boulder/Gravel	Riparian Vegetation: ST Red Cedar
Temperature: 57° F	Fish Species: rainbow trout

MANAGEMENT CONCERNS:

1) Lack of large wood
2) Lack of pools
3) Areas of bank failures

REACH 4

Reach 4 starts at a 25 foot high falls (NSO#172) and ends just pass the third tributary on the left bank at a bank failure location and a change in stream gradient, a distance of 0.9 mile (NSO #173 - 276). This reach is still a narrow V-shaped valley. There are a number of old soil failures along this reach that are showing signs of healing (alders and other plants are growing on them). There is evidence of beaver use.

ROADS/ TIMBER:

Forest Road 2262022 and 2299041 run parallel to this reach. Although these roads are not next to the stream they were used to harvest timber from the riparian zone of Lake Creek. The plantations appear to well stocked and the buffers adequate but would not meet Option 9 standards (less then 300 ft.).

RECREATION:

SMART DATA:
Stream Gradient: 8%	Pools/Mile: 41.1
Bankful Width: 28.91	LWD/Mile: 18.1

Temperature: 50° F	Fish Species: rainbow /cutthroat trout

MANAGEMENT CONCERNS:

1) Lack of pools
2) Lack of large wood
3) Ares of earth slides (mass wasting)

REACH 5

Reach 5 starts at a gradient change and valley form change, to a narrow flat-floor with floor width of 100-300 feet and extends for a distance of 1.8 miles where a change in valley form takes place (NSO 277 - 428). This reach has a number of older healed earthen slides (vegetation growing on them).

REACH 6

Reach 6 starts at a change in the valley form, narrow V-shaped, this reach ends at the U.S.G.S. gauging station below Packwood lake dam, a distance of 0.5 mile (NSO # 429 - 495).

ROADS / TIMBER:

Forest Road 2262000 and 2266041 run parallel to this reach. Forest Road 2266041 ends at a harvest landing about half way through reach 6 and Forest Road 2262000 continues all the way to Packwood Lake. Forest Road 2262000 is the access route to the dam site. The plantations appear to well stocked and the buffers adequate but would not meet Option 9 standards (less then 300 ft.).

RECREATION:

This reach is not easy to access from any direction. Either Forest Road 2262022 or 2266041 will get a recreationist "close". However, they still have to hike across country down some very steep slopes to reach the stream. Due to the ruggedness of the terrain few people use the area. Forest Road 2262000 is the access route to Packwood Dam site, it is not open to the public. The public do use the road as a bike trail or hiking trail to get to the lake. There are signs in Lake Creek in reach 6 that indicate that the area below the dam receives more use than other areas, with the exception of the private lands(reach 1).

SMART DATA:
Stream Gradient: 8%	Pools/Mile: 44.0
Bankful Width: 23.64	LWD/Mile: 7.4
Substrate: Cobble/Cobble	Riparian Vegetation: LT Hemlock
