adults of a waterbug Sigara mullettensis. The only molluscs taken
were several young of Helisoma and Physella. The fish population

is said to include Kamloops trout, lake char, Hastern whitefish Core-
gonus clupeiformis, Columbia River chub, coarse-scaled sucker
Catostomus macrocheilus, squawfish and lake shiner. Specimens of
the four last named were examined

A census of the waterbird population on July 7 is as follows:
loon, 1 pair; Holboell grebe, 1 pair; American bittern, 1; mallard,
« fenales with broods; buffle-head, 2 yearling females; solitary
sandpiper, 1; spotted sandpiper, 1; semipalmated sandpiper, 5;
Wilson phalarope, 3; black tern, 20 to 30 pairs.

According to local report Chief Lake is frequented by large
numbers of ducks during migration; it is little used as a nesting
place

Brule Lake: Approximately 90 acres, about four miles southwest of
Chief Lake in the burned-over area referred to earlier. The shores
are boggy, sedge-covered on the inner, and with horsetail marsh on
the outer, margin. There is considerable growth of water hemlock
Cicuta Douglasii, sedge Carex stipata, dock Rumex Brittanica and
one clump of cattail, the latter introduced, along the shore. The
water surface is more or less covered with yellow pond lily; there
are quantities of pondweeds, and duckweed is abundant amongst the
horsetail. No water birds were observed on this lake.

Murch Lake: 1 1/4 miles long, 1/4 to 1/2 mile wide; about one-half
mile west of Brule Lake. The fire which swept this district was
checked before the shoreline timber was destroyed, so that the
large Douglas fir and Engelmann spruce along the lake are intact.
The shores are part gravel, part boggy with horsetail marshes

The submerged vegetation is similar to that of Brule Lake; the fish
life consists of squawfish, lake shiner, suckers and Columbia River
chub. The only water birds observed were a pair of loons and one
pair of Holboell grebe.

Tsula Lake: A short distance east of Brule Lake is similar in
character This and other lakes in the vicinity are of slight
importance as waterfowl nesting grounds.
