Going east on the county line, at intervals of 160 feet, I found water 
66, 96, 96, and 66 feet deep. 
The lake is well stocked with fish—bass. bluegills, perch, grass-pike, 
and others. Under much of the shallow water there is an abundance of 
workable marl. 
TIPPECANOE LAKE, OR. BIG LAKE, NOBLE COUNTY. 
This lake occupies parts of sections 28, 29, 32 and 33, Town. 33 N., 
Range 9 east. It formerly had an area of about 400 acres, but a ditch has 
lowered the water about 7 feet and reduced the area to about 300 acres. 
Before ditching, fully one-half the area was less than 10 feet deep. 
There is still considerable shallow water in the southeast and southwest 
portions of the lake, but much the greater part of the area is deep water. 
The bluffs are low, not more than 10 to 15 feet above the, water. The 
ditching caused the destruction of a great mass of vegetation, and so 
changed the environment of another great body of plant life that it will 
be many years before the vegetation can adjust itself to the changed con- 
ditions and reach a stable equilibrium. At its present level the lake can- 
not support as much vegetation as formerly. The lake is famous for the 
quantities of fish found in its waters, but they are not as plentiful as 
formerly. On the southwest we found water 380, 85, 46, 47, and 36 feet 
deep, and going northwesterly along the axis of the lake at intervals of 
about 200 feet we found water 50, 65, 72, 65, 50 and 88 feet deep. Deeper 
water was claimed, but we could not find it. There is considerable marl 
in the lake bed, but it is not a workable deposit. 
GOOSE LAKE. 
This lake is in the southwest 4, section 12, Town 52 N., Range 8 E., 
Troy Township, Whitley County. It has an area of about 150 acres. It 
is surrounded by considerable swamp and low land, in which are several 
small ponds. Back of these are several morainic hills rising from 30 to 
50 feet above the surface of the lake. The slopes of the lake bed are rather 
steep and the water is in general quite deep. The lake has been lowered 
about 6 feet by a ditch. This drained adjacent swamps but lessened the 
area of the lake by only a few acres. Fishing is said to be fairly good. 
Commencing on the south and going northerly and westerly at intervals 
of about 100 feet we found the depth as follows: 100 feet out, 17, 20, 
29, 30, 34, 34, 34, 37, 37, 41, 50, 54, 57, 62, 63, 62, and 61 feet; westerly,
