and the same aquatic vegetation as Nukko Lake. No waterfowl were
observed there

Nukko Creek and Chief Lake: The latter 3 1/2 miles long, 3/4 to

2 miles wide; 11/2 miles north of Nukko Lake. A large section

of forest on the west side of the lake was burned about 10 years
ago and is now grown up with aspen, otherwise the surroundings are
similar to those at Nukko Lake. At one place amongst the usual
riparian growth a small clump of wild cherry was observed. Except
in marshy bays the shores are chiefly sand and gravel. Along sec-
tions of the east shore coniferous forest reaches the lake margin.
The water is muddy and is said not to exceed 16 feet in greatest
depth. A growth of horsetail widening to 50 yards or more in
numerous places is almost continuous along the shore and in these
open marshes the pondweeds Potamogeton richardsonii, P
zosteriformis, P. alpinus var. tenuiflora, P. gramineus, P-. nodosus,
P. perfoliatus, and water sinartweed are plentiful. Near the centre
of the lake are extensive beds of Potamogeton amplifolius. On some
sections of the east shore the prevailing horsetail is replaced by
stretches of spike rush Eleocharis palustris, and there is one nar-
row bed of round-steam bulrush Scirpus acutus about 300 yards in
length Two streams passing through thick willow and alder bottoms
enter the lake, one at the south draining Rubai Lake, the other on
the east side draining Swamp Lake. At the mouths of these streams,
and for some distance on either side, are beds of yellow pond lily
and much submerged vegetation including pondweeds of several species.

Chief Lake drains into Salmon River, some four miles to the
north, through Nukko Creek and travel down this stream by canoe is
possible for about one mile where a beaver dam prevents further
progress (Fig 21) Below this the stream bed is steep and rocky.
For a mile or so below the outlet (Fig. 22) Nukko Creek is
contained within a half-mile wide valley filled with sedge-covered
bog so that its channel is not everywhere clearly defined. Sections
of the channel are narow and deep; others widen to pond size and
here yellow pond lily covers some of the deeper portions, while
Robbin's pondweed, bladderwort and water buttercup form thick
beds-of vegetation in the shallows; greater duckweed is abundant.
Sedges of various species are the prevailing type of vegetation on
the boggy shore; there are patches of cattail, and where the shore
is broken down and submerged, are stretches of horsetail, buckbean
and water arum (Fig 23) Amongst the sedges along the stream grow
numerous plants such as bur reed Sparganium multipedunculatun, marsh
skull cap Scutellaria epilobifolia, loosestrife Lysimachia thyrsiflora,
cress Roripa palustris var. glabrata, marsh cinquefoil and dock Rumex
maritimus

Invertebrate life is not abundant judged by the material collec-
ted that consisted of a few amphipods, a beetle Haliplus immaculicollis
Harris, one damselfly and two mayfly nymphs, and seven nymphs, and two
