the following plants: water buttercup, water milfoil Myriophyllum
alternifolium, the pondweeds Potamogeton natans, P. richardsonii,

P. gramineus, P robbinsii, and P. perfoliatus, arrowhead Sagittaria
cuneata, and hornwort Seeds of the latter, probably representing
the previous year's crop, were dredged from the bottom. Elsewhere
were found patches of charophytes and numerous beds of buckbean, the
latter growing in many places along shore and in isolated beds. One
such bed measured approximately 30 feet by 12 feet (Fig. 17). Speci-
eS aa small white water lily Nymphaea tetragona were found here

Animal food was not abundant and constant dredging produced
only a few molluscs, amphipods Hyalella azteca, caddis larvae,
dragonfly nymphs, bloodworms and the heetles Deronectes striatellus
LeC., and Hydroporus sericeus LeC. Molluscs identified are:
Stagnicola palustris nuttalliana (Lea), Helisoma subcrenatum (Car-
penter), Physella ampullaceae (Gould), Pisidium variabile Prime and
Pisidium adamsi Prime. A large mussel Anodonta kennerlyi Lea is
fairly plentiful

The lake is said to have a fish population of Kamloops trout,
lake char Cristivomer namaycush, suckers, squawfish, Columbia River
chub and lake shiners. Examples of the three species last named
were examined.

No ducks or grebe were observed; it seems probable that the
marshy bays provide feeing places for waterfowl on migration. The
lake and its surroundings are sub-marginal nesting ground.

Muskeg Lake: A short distance south of Summit Lake and close to
the Summit Lake-Prince George Road, is a five acre pond partially
covered with pond lily leaves Surrounding it on three sides is
open muskeg containing a variéd bog and alpine flora that includes
a dwarf willow Salix pediculates var. hypoglauca, cranberry
Oxycoccus quadripetalus, Labrador tea Ledum groenlandicum, wild
rosemary, buckbean, false asphodel Tofieldia glutinosa, dwarf
raspberry Rubus acaulis and long-leaved sundew Drosera anglica.
Between the open muskeg and the margin of the forest are isolated
clumps of dwarf birch.

No ducks were on the lake, the only water birds seen on each
of several times the muskeg was visited being two adult greater
yellowlegs. The land bird population was small and limited to
song sparrows and Lincoln sparrows.
