Construction Of wing dams continued,
under the contract in force at the begin
nIng of the year, until September, 'sS, and
the dredging was suspended in Decem-
Der, 'S3. for lack of funds. A survey Of
the river has been made from Venus
Point to Tybee knoll for use in the fur
Their improvement of the river. al Of the
dams and the adjacent channels have been
recently examined fundamentally.
CRoss-TIDEs DAM.
No material change; no work done.
GARDEN BANK sHoAL.
The channel defined by the 19-foOt m. b.
W. curves has narrowed somewhat. but its
minimum width of last year, 500 feet, has
not changed: il has shoaled an average Of
IL feet. The least mean high water
sounding along the channel is 1872 feet,
the deepest is 22.9 feet.
WRECKS CHANNEL.
Eight thousand four hundred and forty
eight cubic yards were dredged in July,
1888. The Jetty is in good condition. The
filling in continues both between the
spurs and north of the jetty. Along the
upper and middle part of the channel but
little change is observed. The lower pOr-
tiOn is one to three feet deeper than last
year, and the part deeper than nineteen
feet mean high water, is more uniform
and has widened to $50 feet from a width
OF 100 feet. The shoalest sounding along
the range is 1871 feet mean high water,
with 20 south of the range.
HEAD OF ELBA ISLAND.
No work done. Dam at this point shows
no settlement. A shoaling of two feet s
shown over a small part of dredged cut;
depth of latter has in general been main
tanned. Steamers have no trouble.
UPPER FLATS CROSSING.
Wing dam No. % was completed. A
cut go feet wide was dTedged between the
dams and continued 1000 feet below the
lower set. Dams have not settled.
Channel has been very much improved

tion 10 feet at m. b. W. could not be car
