The St. George River extends 10 miles in a northeasterly direction to the town of Thomaston. The approach to the entrance of St. George River has very broken and irregular bottom, with numerous ledges bare and submerged. Strangers should proceed with caution and avoid crossing broken areas where the charted depth does not greatly exceed the draft.
The channel depths in the river up to Broad Cove range from about 22 feet to over 80 feet; above this, the depths gradually decrease and the channel narrows to a small stream through extensive flats that bare at low water. From a point about 1 mile below Thomaston, a narrow channel, subject to shoaling, was dredged to a depth of 16 feet. The channel in the upper river is marked by buoys, some of which are uncharted because they are frequently shifted to mark the best water. The sharp bend in the dredged channel near Thomaston is marked by a seasonal light.
St. George River is crossed at Thomaston, above the wharves, by a fixed highway bridge with a clearance of 5 feet; the nearby overhead power and telephone cables have a clearance of 40 feet.
