Michigan Department of Natural Resources Cass County (T6S, R13-14W, Sections 19 and 24) Surveyed June 27-28, 1990 James L. Dexter, Jr. Environment Kirk Lake is a natural lake located in east central Cass County (see
map of Kirk Lake). It lies about 2 miles east of the small town of
Vandalia. Small rolling hills characterize the topography of the area.
The northeastern shoreline is owned by the State of Michigan (Crane Pond
State Game Area). The watershed is a mixture of cultivated farm fields, pig farms, and
woods. No information exists on the soil types of the area. Kirk Lake is 41.5 acres in size and has a maximum depth of 23 feet. Shoals,
composed mostly of pulpy peat and marl, make up about 40% of the lake
area. Aquatic vegetation is abundant throughout the lake. Floating and
emergent species ring the entire lake to a depth of about 5 feet. Belas Lake is the source of the only inlet. An outlet drains west into
Wildcat Drain and eventually into Christianna Creek. Both inlet and outlet
are rated as second quality warmwater streams. This small watershed lies
in the St. Joseph River Basin. Water quality conditions were studied on July 27, 1990. The color of
the water was light brown, and Secchi disk readings were 11.5 inches.
Within the water column, alkalinity ranged from 144 ppm at the surface
to 162 ppm at the bottom. The pH was 7.8 at the surface. These values
indicate that the water is well buffered and very hard. Water temperatures
ranged from 76.1°F at the surface to 55.4°F at the bottom (20
feet). A thermocline began at 8 feet. Dissolved oxygen levels were sufficient
for fish to a depth of 11 feet (2.5 ppm). Surface oxygen levels were 8.1
ppm. Development is very limited on Kirk Lake, because much of the surrounding
shoreline is marshy or wet. An access site exists on the south side of
the lake. This site can handle up to five vehicles with trailers. There are few historical records for this lake. Bluegills were stocked
from 1934 through 1940. During the late 1940's, there was good fishing
for bluegill, largemouth bass, and fair fishing for perch and black crappie.
White suckers and bowfin were said to be numerous. This same type of fishery
was documented in a 1973 netting survey. Growth rates of bluegill and
crappie were well above state averages. Before the access site was upgraded in 1980, access to the lake was possible
only by a very poor trail road. This was passable only in dry periods,
which kept angler use of Kirk Lake to a minimum. During this most recent survey, three different types of nets (2 each)
were fished for one night. These nets included standard 6' x 3' x 1.5"
trapnets, mini-mesh (¼") full-size fyke nets, and 125'-long experimental
gillnets. The fish community found during this survey (Table 1) was virtually
unchanged from previous surveys. However, a few species were found in
the 1990 survey that had not been previously recorded. These included
carp, pumpkinseed sunfish, and shortnose gar. No black crappies were collected
in this survey, although they had been found in the past. The present fish community of Kirk Lake is dominated by good numbers
of large bluegills. More than 76% of the bluegills captured were 6 inches
or larger, and 43% of these were over 7 inches. Schneider (1990) developed
five criteria for ranking bluegill populations from survey catches in
Michigan. Using these criteria, Kirk Lake bluegills ranked about 5 (good)
on a scale of 1-7. Data from the 1973 survey ranked bluegills at 4.8,
or slightly below the current ranking. Bluegills as large as 9.5 inches
were collected in the 1990 survey. Only a few northern pike, largemouth bass, and yellow perch were collected
in this survey. The northern pike may be the offspring of 100 fall fingerlings
stocked into Belas Lake in 1954. Too few of these species were collected
to make any determination about their status. One angler reported that
bluegill, crappie, and northern pike fishing at Kirk Lake was very good,
and that most angler pressure occurred during the winter. Growth rates of bluegills were just above state average (Table 2). The
few largemouth bass, yellow perch, and northern pike collected were growing
at state average rates. The age composition and survival characteristics of bluegills appear
to be normal considering that relatively few small fish were sampled (Table
3). Significant mortality, either from fishing or natural causes, apparently
takes a large portion of the bluegills between age IV and V. Fishing at Kirk Lake can be a very enjoyable experience. Limited development
and low fishing pressure lend a wilderness aura to the lake. Compared
to other area lakes similar in chemical and physical properties, Kirk
Lake is a good fishing lake. The bluegill population is better than those
found in many other lakes. Natural reproduction by northern pike should
be a welcome addition in this area where pike are sparse. No intensive management activities need to be undertaken for this lake.
The fishery, the surrounding lake shore area, and the watershed should
not be undergoing any major changes in the near future. Kirk Lake should
continue to produce a high quality warmwater fishery for years to come.
A favorable balance among natural reproduction, growth, species mix, and
low public use will all contribute to maintaining the good health of the
fish community. Report completed: June, 1991. Schneider, J. C. 1990. Classifying bluegill populations from lake survey
