Blackwater Bay is a large body of water along the crownlands in eastern Westeros. King's Landing, the capital of the Seven Kingdoms, sits where the Blackwater Rush pours into the bay. "Waters" is a common bastard name around Blackwater Bay.
Blackwater Bay is an inlet of the narrow sea, separated from it by the Gullet, held between the arms of Crackclaw Point to the north and Massey's Hook to the south, with the island of Dragonstone guarding the entrance to the bay. Massey's Hook shields against the rougher narrow sea, so Blackwater Bay has calmer waters. Elements of the Iron Throne's royal fleet patrol the bay and ensure it is kept free from piracy.
Aside from King's Landing and Dragonstone, the largest port on the bay is Duskendale, which serves as a secondary port for King's Landing when the main port is overwhelmed with traffic. Rook's Rest is located on the northern shore of the bay and Sharp Point is to the east at the tip of Massey's Hook. The kingswood extends along the southern shore of Blackwater Bay, with the Wendwater flowing into the bay.
A unique geological feature called the spears of the merling king sits within the bay. Within the spears, the currents are strong and treacherous. Waterfowl are abundant in marshes along Blackwater Bay, and the body of water also contains codfish.
The shores of Blackwater Bay were historically disputed by river kings, Storm Kings, Kings of the Isles and the Rivers, and kings from House Darklyn of Duskendale and House Massey of Stonedance.
During the Dance of the Dragons, the blacks blockaded Blackwater Bay by closing the Gullet with the fleet of Lord Corlys Velaryon. The greens tried in vain to break the blacks' naval superiority in the Battle of the Gullet, but sacked Spicetown so severely it was never rebuilt.
A Clash of Kings
The Battle of the Blackwater occurs at the mouth of the Blackwater Rush where it meets the bay. This battle pits the forces loyal to Stannis Baratheon against those loyal to Joffrey Baratheon. Tyrion Lannister, the acting Hand of the King at the time, devises a system with a chain boom pulled across where the river widens into the bay. This chain is raised once the majority of Stannis's fleet is up river and wildfire is deployed to ignite many of the ships. The current pulls these burning ships towards the mouth of the river and against the chain, which results in the destruction of much of the fleet. Salladhor Saan's galleys remain outside of the chain in the bay.
