iii Jean Lake

1. SUMMARY

Jean Lake is located in the Vanderhoof Forest District, 20 km north of the town of Fraser Lake. Reconnaisance inventory of the lake was made 05 - 06 September 1995. The lake covers 54 surface hectares and is ovoid in shape, with two distinct basins separated by forested islands. The lake is intermediate in depth (mean and maximum depths of 5.7 m and 14.2 m); most shorelines are gravel and cobble. It lies 1021 m above sea level and drains via an unnamed creek to Duncan Creek, the Sutherland River, Babine Lake and the Skeena system. Access was achieved by floatplane from Burns Lake; the closest road is located about 1 km north of the lake.

Jean Lake is moderately acidic with very low specific conductance. At the time of survey the lake was strongly stratified, with the thermocline at about 6 m below the surface. Oxygen levels in the hypolimnion would have excluded any use of that volume by Jean Lake fish populations. Phosphorus and nitrogen concentrations imply oligotrophy and low productivity.

Lake fish populations were sampled by overnight sets of one standard 91m experimental multi-mesh sinking gillnet and 4 minnow traps baited with salmon roe. Five species of fish were captured in Jean Lake: rainbow trout (Oncorhynchus mykiss), longnose sucker (Catostomus catostomus), redside shiner (Richardsonius balteatus), lake chub (Couesius plumbeus), and prickly sculpin (Cottus asper). Prickly sculpin and lake chub were captured in low numbers, relative to the other species. Rainbow trout maximum length and population condition factor were typical of small lake rainbow trout populations in north central British Columbia.

The lake outlet and four unnamed inlet channels were examined for fisheries potential. The outlet channel and at least one of the lake inlets support habitat seasonally suited to rainbow trout reproduction, though discharge was low due at the time of the survey. Visual observation and minnow trapping revealed redside shiner, lake chub, longnose sucker and prickly sculpin in the outlet channel only.

The shape of the lake basin, the presence of forested islands, and the relatively pristine surroundings contribute to the beauty of the area. The lake and its surroundings are already a moderately exploited recreational resource. Protection of the fish populations of Jean Lake is not of special concern at this time. The immediate area of the lake is not likely to be subject to industrial activity in the near future, due to the forest stage. However, the aesthetic nature of the area and its location only 20 km north of the developed Highway 16 corridor make this lake a strong candidate for ‘remote lake’ designation, to be maintained without road access.

3.3 Benchmark

The benchmark was established in a lodgepole pine on the E shore, 50 m S of the NE corner of the lake. An spike was placed in the center of an orange circle painted on the tree trunk, 1.0 m above the current lake level and 0.3 m above the ground.

3.4 Prior Surveys

A search of Skeena Region inventory files yielded no records for Jean Lake.

3.5 Lake Drainage

Quantitative characteristics of the stream surveys and of fish collection methods and results can be found on the stream survey forms in Appendix B and the fish sampling data sheets in Appendix C. Numbering of the streams (S1, S2) in this section corresponds to labels on Figure 2 and other figures and tables in this report. The NTS 1:50,000 mapsheet 93K/02 shows three unnamed channels which were examined.

S1. Unnamed outlet stream of Jean Lake, WC 480-9936-709-386, surveyed at UTM 10.376849.6012319 (WCD). This low-gradient stream likely provides most of the spawning habitat for the Jean Lake rainbow trout population, as it has no barriers to fish passage near the lake and contains good spawning gravels and rearing habitat. At the time of the survey, there was no discernible flow but the stream was watered and at moderate stage. An overnight set of two minnow traps captured redside shiner, lake chub, longnose sucker and prickly sculpin.

S2. Eastern of two unnamed channels leading into the on the south shore, probably WC 480-9936-709-386, UTM at entry to lake : 10.376250.6011875 (NAD27). At time of survey, the channel was watered from the lake only to a point 200 m upstream, with no discernible flow. This low gradient stream may support some rainbow trout spawning during spring and early summer high flows, as suitable gravels were present. Neither angling nor an overnight set of a single minnow trap captured any fish.

5 Jean Lake

• Western of two unnamed channels leading into the wetland on the south shore, probably WC 480-9936- 709-386-821. This dry channel does not reach the lake; the wetland into which it drains also did not contain surface water. The channel ends in the wetland at UTM 10.376100.6011800 (NAD27) . This channel probably does not convey a stream with habitat which is accessible to the Jean Lake fish populations, even during the spring and early summer.

In addition, two channels entering the lake along the west shore, not shown on the NTS 1:50,000 mapsheet 93K/02 but visible on air photo 30BCB91067 No. 111, were also examined. • Unnamed southern channel, UTM 10.37585.6012325 (NAD27). The channel was dry at the time of the survey. The substrate contained gravels which would be suitable for salmonid spawning, although gradient near the lake was estimated as 3% so substantial flow would be necessary.

• Unnamed northern channel, UTM 10.37585.6012400 (NAD27). The channel was dry at the time of the survey. The substrate was organic fines. This channel probably does not bear a stream with habitat which is of any importance to Jean Lake fish populations.

3.6 Terrain and Vegetation

3.6.1 Immediate Shore The shore in the northeast corner of the lake is a mixed sand and gravel beach. Most other shorelines are a 2 m wide band of flooded sedges, rooted in sand, gravel and small cobble overlain by vegetative debris. A one to two tree layer of alder separates the shoreline from the surrounding pine forest. Sedge are located along the east and south shores.

3.6.2 Surrounding Country The surrounding country is comprised of low rolling hills, forested mainly by lodgepole pine with pockets of mixed spruce, subalpine fir and aspen. The lake lies near the northeast edge of a large area (~ 150 km2 ) dominated by immature lodgepole pine aged 41- 60 yrs, probably the result of a fire in the 1940’s.

4. ACCESS, DEVELOPMENTS AND LAND USE

4.1 Access

The lake was accessed by DeHavilland Beaver from the floatplane base on Burns Lake, air distance of 58 km. The closest road to the lake accesses the cutblocks about 1 km north of the lake, and is a branch of the Sutherland Forest Service Road system.

4.2 Development and Land Use

4.2.1 Resorts and Campsites There are no resorts or developed campsites at the lake.

6 Jean Lake

4.2.2 Mining Claims The lake is located in a reserve in the Omineca Mining Division, with no placer staking allowed (B.C. Reg. 333/88). Four-post registration files for the area showed one claim, #10476, expired 7 May 1993. No signs of mineral exploration or mining activity were observed at the lake.

4.2.3 Timber Harvest The lake lies within the West Fraser Mills North operating area, in the Prince George TSA. Five cutblocks extend in an east-west line about .75 km N of the lake. Most of the harvesting in these blocks took place between 1974 and 1976, and the restocking occurred in 1979. The blocks are not visible from the lake, and only very limited timber harvest activity (< 1% of the visual field) is visible in the distant NW, from some vantage points on the lake surface. The absence of timber harvesting activity to the south and west is likely a result of the dominance of immature lodgepole pine, probably due to fire about five decades ago.

4.2.4 Waste Permits A search of Skeena Region waste permit files yielded no records for Jean Lake.

4.2.5 Water Permits A search of Skeena Region water permit files yielded no records for Jean Lake.

4.2.6 Obstructions and Pollutions No beaver dams or other obstructions were observed in the vicinity of the lake, on its inlets / outlet streams. Beavers were present at the lake, and any dam near to the lake on its outlet could have an impact on salmonid access to spawning habitat.

4.2.7 Recreation Resource Inventory Forest Service Recreation Resource inventory was unavailable for the polygons containing the lake. It is likely that ROS status would be Class 2 “Semi-Primitive Non-Motorized”.

4.2.8 Special Regulations and Restrictions None known.

4.2.9 Comments A good ATV trail to the northeast corner of lake from the cutblock to the northeast. Numerous pine martin trap boxes were located along the 2.5 km trail. There were two small boats and signs of recent hunter use near the shore at the northeast corner of the lake, which probably also offers the best spot for camping and floatplane disembarking. Other rough trails parallel the shore through dry areas.

5. FISH POPULATION SAMPLING

Details of fish population sampling in Jean Lake and its outlet / inlets are given in Table 1. Raw data were recorded on RIC standard “Fish Collection Method Information Forms” and “Fish Collection Data Forms” which are reproduced in Appendix C. All landed catch was sampled for appropriate parameters, except fish which escaped as the gear was retrieved, or fish whose condition did not allow measurement.

Table 1. Fish sampling effort and catch for all methods used at Jean Lake and its inlet-outlet streams, 05 - 06 September 1995. Lake = Jean Lake, S1 = unnamed outlet stream of Jean Lake, WC 480-9936-709- 386, S2 = unnamed inlet to the S shore of Jean Lake, WC 480-9936-709-386. GN = MOE / RIC standard experimental sinking gillnet, length 91.2 m and width 2.4 with panels (in order) of 25, 76, 51, 89, 38, and 64 mm mesh. The set was made perpendicular to shore with the smallest mesh at shore. MT = Gee-type minnow trap baited with salmon roe; AG = angling. Set and Haul are 24 hour clock times. Catch is the total catch for that method, by species: CAS = prickly sculpin, LKC = lake chub, LSU = longnose sucker, RB = rainbow trout, RSC = redside shiner. Number of captured fish which were sampled for length (non- salmonids) and all parameters (salmonids) are listed in parentheses after the total number caught. Where no number is listed in parentheses, the entire catch of that species was sampled.

5.1 Fish Species Composition

Five species of fish were captured in Jean Lake and its watershed: rainbow trout (Oncorhynchus mykiss), longnose sucker (Catostomus catostomus), redside shiner (Richardsonius balteatus), lake chub (Couesius plumbeus), and prickly sculpin (Cottus asper). Special status in MOE Region 6 is not currently attached to any of these species. Prickly sculpin and lake chub were captured in low numbers, relative to the other species (Table 1). The presence of rainbow trout in Jean Lake requires that its low-gradient inlets and outlet be considered fish-bearing streams of class S3 or S4 under the Forest Practices Code.

5.2 Relative Abundance

To sample a steep shore with rocky substrate, the Jean Lake gillnet was set through the thermocline. A considerable portion of the net was fishing in the oxygen-depleted hypolimnion. Catch per effort was probably much lower than would have occurred were the net fished at a different location in the lake.

5.3 Size, Age, and Growth

Characteristics of the length distribution of fish captured by angling, gillnet and minnow trap in Jean Lake and its outlet, are shown in Table 2 and Figures 3 and 4. Due to gear selectivity, the samples are probably not representative of the true length structure of Jean Lake fish populations. Growth and maximum length of rainbow trout appear typical of or slightly better than most small lake populations in north central British Columbia.

Estimated terminal length (L∞ ) occurs at the intersection of the regression line with the diagonal reference line; the parameters from the regression give k = .614 and L∞ = 296 mm.

5.4 Sexual Maturity and Condition

5.4.1 Rainbow Trout Sample sizes are low, but rainbow trout sexual maturity appears to occur between ages 4 and 6 for females, and at age 6 or later for males in Jean Lake (Table 3). The population condition factor appears typical of small lake rainbow trout populations in Skeena region during late summer (Figure 7).

6. LIMNOLOGICAL SAMPLING

Limnological sampling was conducted at midday 06 September 1995, at the Jean Lake limnology station labelled on Figure 2. Raw data and associated information were recorded on the RIC standard “Lake Biophysical Data Form” which is reproduced in Appendix D. Water samples were collected at 0.5 m and 14.0 m depths, apportioned into aliquots for general chemistry, metals, and dissolved metals analysis and shipped to Zenon Laboratories for processing. Zenon’s records show that the Jean Lake samples were received on 08 September 1995, within the 72 hr RIC standard time frame for water sample transport.

6.1 Stratification

The oxygen - temperature profile of Jean Lake on 06 September 1995 is shown in Figure 8. The lake was strongly stratified, with the inflection points of the oxygen and thermal profiles both at about 6 m below the surface. Oxygen levels in the hypolimnion would have excluded any use of that volume by Jean Lake fish populations.

6.2 Water Chemistry

Results of the general chemistry and metals analyses by Zenon Labs are given in Table 4 and Table 6. Jean Lake is moderately acidic with very low specific conductance. Phosphorus and nitrogen concentrations imply oligotrophy and low productivity. Estimated N : P ratio of the hypolimnion (Table 5) was greater than 150 : 1, suggesting phosphorus limitation of algal growth above in the epilimnion. The most striking feature of the metals analysis is the reduced availabilty of (Mn) in the epilimnion relative to the hypolimnion.

Table 6. Metals concentrations estimated by Zenon Laboratories. Sample collection is described in the caption to Table 4. Dissolved metals aliquots were filtered by 0.45µm cellulose acetate membrane syringe. All metals aliquots were fixed immediately after collection with 1 ml HNO3 . Analysis was performed using a Jarrell-Ash Model 61E (inductively coupled argon plasma analysis); “total metals” aliquots were subjected to HNO3 digestion by Zenon. For values labelled with (1), the dissolved metal concentration was greater than the total concentration. MDC = minimum detectable concentration for the analytic method.

7. OTHER FLORA AND FAUNA

7.1 Aquatic Plants

More than 99 % of lake surface is open water. Some flooded sedges and swamp horsetail grow at the lake perimeter. A few mixed macrophyte beds are dominated by Potamageton sp. and Nuphar polysepalum.

7.2 Zooplankton

The Jean Lake zooplankton community was dominated by small cyclopoid copepods and their immature stages. Small to moderate-sized daphnids were also abundant and displayed late-season morphology (head elongation) often associated with predation pressure. Macrozooplankton such as amphipods and chaoborids were not present in the plankton. The zooplankton species composition and size structure was suggestive of relatively intense planktivory by the lake’s abundant rainbow trout.

Table 7. Zooplankton collected by horizontal tow of a 118 µ mesh conical plankton net, Jean Lake offshore, 18:40 h. on 05 September 1995. Net mouth diameter was 15 cm and net length was 1 m. Tow duration was 3 minutes, at velocity of 0.4 m/sec and depth between 0 and 2 m.

7.3 Waterfowl and Other Fauna

Beaver were active on the lake during the field visit, and two lodges were visible. Loons and an osprey were observed fishing on the lake. Moose and bear sign were abundant. Other aquatic fauna included western spotted frogs.

8. MANAGEMENT COMMENTS

Jean Lake provides a highly aesthetic setting, and pleasant angling for moderate-sized but abundant rainbow trout. The lake is fairly deep for its size and probably does not winterkill, unlike many small in the region. Jean Lake is oligotrophic, as evidenced by the low specific conductance and phosphorus concentrations and high Secchi depth. Abundant spawning habitat is currently available, despite beaver activity in the area. Low primary production, spawning habitat abundance, and the presence of competitor fish species probably all contribute to the low terminal length of the rainbow trout. Nevertheless, the trout are plentiful, in good condition and large enough to provide enjoyable recreation. Depth sounder traces showed some suggestion that larger fish may be present in the lake. Fish sampling did not indicate the presence of lake char, but Jean Lake could possibly support this species, given its depth and the abundance of suitable rocky substrate.

The shape of the lake basin, the presence of forested islands, and the relatively pristine surroundings contribute to the beauty of the area. Boats stowed at the lake, and trails and other signs of hunting and trapping activity, suggest that this lake and its surroundings are already a moderately exploited recreational resource. Protection of the fish populations of Jean Lake is not of special concern at this time. The immediate area of the lake is not likely to be subject to industrial activity in the near future, due to the forest stage. However, the aesthetic nature of the area and its location only 20 km north of the developed Highway 16 corridor make this lake a strong candidate for ‘remote lake’ designation, to be maintained without road access.

UTM values were obtained from two sources. 1. For lakes, UTM at the outlet was obtained from the WCD; this is noted after the UTM. 2. For stream reaches at lake outlets, UTM for the lake outlet is used, and referenced as WCD. Otherwise, UTM for the surveyed reach was estimated from NTS 1:50,000 mapsheets, using interpolation. UTM datum year (i.e. NAD27) is recorded after the estimate.

Native land claims information was derived from the following sources: 1. Northern Interior Negotiating Region, Statements of Intent, August 31 1995. Ministry of Forests Aboriginal Affairs Branch.

The NTS mapsheet shows this this channel ending in swamp before reaching the lake, but in fact it does reach the lake and at higher flows would be passable to fish
