Waccamaw River rises at Lake Waccamaw, N. C., and flows southwest 142 miles into Winyah Bay, just above Georgetown. In June 1934 there was a controlling depth of 12 feet (3.7 m) to Conway. From Conway to Red Bluff a depth of 234 feet (0.8 m) obtained. Above Red Bluff, no work having been done for several years, the channel is obstructed by logs and snags and cannot be navigated safely. The Intracoastal Waterway northward from Winyah Bay, when completed, will follow the natural waters of the Waccamaw River to a point about 7 miles northwest of Murrell Inlet; thence through a land cut to a point in the headwaters of Little River.

Pee Dee River rises in the mountains of North Carolina and flows generally southeast for 435 miles into Winyah Bay just westward of Waccamaw River. Above the Uharie River, 233 miles from the mouth, it is called the Yadkin. In June 1934 a depth of 9 feet (2.7 m), by way of Bull Creek, obtained to a point 52 miles above the mouth and 3 feet (0.9 m) to Jefferys Creek. Above Jefferys Creek the river cannot be safely navigated because of many snags and sunken logs.

Black River empties from northward into Pee Dee River about 32 miles above its mouth; it is navigable for river steamers for a distance of 44 miles. Mingo Creek empties into Black River, about 22 miles above its mouth; it has a low-water depth of about 8 feet (2.4 m) for a distance of 10 miles to Hemmingway Bridge, the head of navigation, but there are many sharp bends.

Sampit River is entered from Winyah Bay through a dredged channel 400 feet wide with a controlling depth of 162 feet (5.0 m) in July 1935. The river entrance is protected on the eastern side by a timber and brush training wall 2,000 feet long. The outer end of the training wall is marked by Sampit River Jetty Light (flashing red). The Sampit River is entered on Sampit River Range (front light flashing red, rear light occulting white) located northwest of Hare Island. The depth in the river channel for a distance of 212 miles above the dredged channel is 18 feet (5.5 m) and this is the depth abreast the city of Georgetown. The principal landing above Georgetown is Sampit, about 10 miles above the mouth of the river.

Pilots.-Pilotage for Winyah Bay is compulsory for certain vessels. There is no regular pilot boat, but pilots will come out upon signal. Rates of pilotage-Georgetown, S. C., effective May 15, 1933

Towboats are employed by sailing vessels and may be had from Georgetown by making the signal when outside the bar.

Anchorages. Good anchorage can be found anywhere in the bay between Georgetown Lighthouse and South Island Light. There is a limited anchorage in the upper part of the bay off the mouth of Sampit River, and between Western Channel Lights No. 13 and No. 15. On account of the limited swinging room, only small craft anchor in the Sampit River abreast Georgetown.

Quarantine. The quarantine boarding station, formerly maintained near Georgetown, has been discontinued. The old station on South Island has been abandoned.

Storm warnings are displayed at Georgetown and Georgetown Lighthouse. Notices regarding displaying and taking down storm signals are telephoned to Georgetown Lighthouse from Georgetown. Tides.-The mean rise and fall is about 32 feet (1.0 m). The tide at Georgetown Lighthouse occurs about 25 minutes later than at Charleston, while at Georgetown it occurs about 1 hour 35 minutes later.

Currents. The tidal currents in Winyah Bay vary in velocity with the state of the rivers emptying into it, as well as with the stage of the tide. Their velocity is greatest between the jetties, where, at strength, it is 2 to 3 knots. The set is diagonally across the south jetty. During freshets in the rivers, also with westerly winds, the buoys between the jetties are nearly towed under at times on the ebb. Off South Island the average velocity is from 2 to 211⁄2 knots, increasing somewhat with the springs. Between North and South Islands the set of the flood current is toward Mud Bay until past the north point of the latter, when the set is more westward. Northward of Frazier Point the flood sets into the channel eastward of Hare Island and also into Waccamaw River. In the western channel the current sets generally fair with the course to be steered.

Remarks and dangers.-There are no dangers eastward of the entrance. The dangers southward of the entrance are described with the coast from Winyah Bay to Charleston. The south jetty is covered at high water, with the exception of the three mounds on it, which are 5 mile apart. Winyah Bay South Jetty Light, on the mound at the end of the jetty, and Georgetown Lighthouse are described with the coast preceding. The Middle Ground is extending seaward, and its eastern end should be given a good berth when off the entrance.

DIRECTIONS, WINYAH BAY

Approaches, from eastward.-From a position about 1 mile south of Frying Pan Shoals Lightship make good a 2582° true (W. 3⁄4 S. mag.) course for 78 miles to a position about 100 yards south of Winyah Bay Lighted Whistle Buoy 2 WB.

From a position about 200 yards northwest of Cape Fear River Entrance Lighted Whistle Buoy 2 CF make good a 2332° true (SW. % W. mag.) course for 65 miles to a position about 100 yards south of Winyah Bay Lighted Whistle Buoy 2 WB.

From southwestward.-From a position about 200 yards southeast of Charleston Lighted Whistle Buoy C make good a 60° true (NE. by E. 2 E. mag.) course for 37 miles to a position about 1/2 mile

southeast of Hector Wreck Lighted Bell Buoy 4 CR and 15 miles 96° true (E. 34 S. mag.) of Cape Romain Lighthouse. Then steer 3° true (N. 1/2 E. mag.) for 7 miles; Winyah Bay South Jetty Light will then bear 324 true (NW. by N. mag.). Then steer 356° true (N. 1% W. mag.) for 5 miles to a position 100 yards south of Winyah Bay Lighted Whistle Buoy 2 WB.

Georgetown, S. C., population 5,082 in 1930, is situated on the north bank of the Sampit River, just inside its mouth; it has considerable trade in lumber, naval stores, and cotton. It is the terminus of a branch of the Seaboard Air Line Railway. The river trade to the Santee, Waccamaw, and Peedee Rivers is considerable. There is sufficient depth at the wharves for vessels able to enter the bay, and there are convenient, sheltered berths for small craft.

Supplies. Provisions, gasoline, and fresh water in quantity and a limited amount of ship-chandler's stores and coal can be obtained at Georgetown.

Repairs. Facilities for making repairs at Georgetown are limited; there are small machine shops and one marine railway of about 100 tons capacity for hauling out boats of 4-foot (1.2 m) draft forward and 7-foot (2.1 m) aft. There is a marine railway at Waverly Mills, on the Waccamaw River, 12 miles from Georgetownlength, 90 feet; draft, 6.5 feet (1.9 m) at high water.

United States Public Health Service. The nearest marine hospital is at Savannah, Ga. At Georgetown there is a relief station (third class) of the United States Public Health Service.

WINYAH BAY TO CHARLESTON ENTRANCE

(Charts 1238, 1239)

Between Winyah Bay and Charleston Harbor an inside passage is afforded by the Intracoastal Waterway. Dredging of this section of the waterway to a depth of 10 feet (3.0 m) is now in progress (April 1935). In September 1935 it was reported that navigation at mean low water was restricted to a draft of 32 feet (1.1 m) at one point and 52 feet (1.7 m) through several reaches between Minim Creek and Charleston. Shoaling had reduced the depth at mean low water in the northerly section of the Estherville and Minim Creek Canal to 7.8 feet (2.4 m).

Along the coast there are a number of rivers and inlets into which depths of from 1 foot to 6 feet (0.3 to 1.8 m) can be carried from sea at low water. These inlets are changeable in character, and, although recent surveys have been made, the chart may not show present conditions. Suitable anchorages can be found inside these inlets or in the waters tributary to them. The channel at most of these entrances trends in a general northerly direction, and shoals and breakers pretty well mark the edges of the channels inside of the bars. The entrances to the North Santee River and Bull Bay are less difficult of navigation than the other entrances in this locality. Except in an emergency, however, none of the entrances should be attempted without favorable conditions and local knowledge.

Santee River is one of the largest rivers of South Carolina and empties into the ocean between Winyah Bay and Cape Romain. There are two mouths, known respectively as North Santee and South Santee; both are obstructed by shifting bars, with little depth, as shown on the chart. The Santee River is formed by the junction of the Wateree and Congaree Rivers, 124 miles above its mouth, and is navigable throughout. Wateree River is navigable 58 miles to the town of Camden and Congaree River 44 miles to the town of
