The Blackwater Rush, also known as the Rush or the Blackwater River, but more commonly called the Blackwater, is a river in the southern riverlands, the northern reach, and the crownlands with some headwaters in the westerlands. It is one of the major rivers of the Seven Kingdoms of Westeros.
With headwaters near Stoney Sept, the Blackwater flows southeast and is joined by two tributaries, one east of Stoney Sept and one from the Gods Eye. King's Landing, the seat of the Iron Throne, is situated at the mouth of the Blackwater Rush at Blackwater Bay, and the River Gate is on of the capital's gates. The Goldroad crosses and follows some of the Rush. Tumbler's Falls is also located on the Blackwater Rush.
A deep and swift river, the Blackwater's currents are wicked and treacherous. The current is strong where the Blackwater Rush meets Blackwater Bay. Although the Rush is a wide river at its mouth, it is only a fifth as wide as the Rhoyne in Essos.
In the days of the Hundred Kingdoms, the mouth of the Blackwater was claimed by the Darklyns of Duskendale, the Masseys of Stonedance, and the river kings of Houses Mudd, Fisher, Bracken, Blackwood, and Hook. The river's mouth was successfully claimed by King Benedict II Justman.
Prior to Aegon's Conquest, the southern shore of the Blackwater was claimed by Argilac Durrandon, the Storm King, and the northern shore by Harren Hoare, the King of the Isles and the Rivers. After landing at the mouth of the river, Aegon the Conqueror founded the Aegonfort. The new king had the swords of those slain in the Field of Fire sent downriver as material for the Iron Throne.
A new town developed at the mouth of the Blackwater Rush during the Conquest. After being anointed by the High Septon at Oldtown, Aegon I chose to make the court of House Targaryen at this new settlement, which would become known as King's Landing.
A cog on the Blackwater was used as a temporary sept for King's Landing, and then a stouter building of daub-and-wattle was built on the shore. The High Septon then sponsored the building of a more impressive permanent sept at Visenya's Hill.
After the yielding of Harrenhal in the Dance of the Dragons, Prince Daemon Targaryen and Caraxes followed the Blackwater downstream to participate in the participate in the fall of King's Landing. Moslander of Yore, Ser Garrick Hall of Middleton, Ser Merrell the Bold, Ser Roger Corne, and Lord Owain Bourney were men of the Blackwater who participated in the First Battle of Tumbleton.
Baela Targaryen enjoyed moonlight swims in the powerful river. Lady Buckler and her daughters drowned en route to the Maiden's Day Cattle Show of 133 AC when their boat sank in the Blackwater.

A Clash of Kings
After being stopped at the Red Fork in the Battle of the Fords, Lord Tywin Lannister joins Lord Mathis Rowan and Lord Randyll Tarly near the headwaters of the Blackwater. At Tumbler's Falls they meet Lord Mace Tyrell, who has brought barges and a large host with him. From there they float down the Blackwater and land a half day's ride outside of King's Landing.
During the Battle of the Blackwater, many of the ships of Joffrey Baratheon and his uncle Stannis Baratheon are set ablaze by wildfire after a great chain divides the river from Blackwater Bay. The Rush appears to be on fire, and King Joffrey has Antler Men flung into the river. Podrick Payne knocks the armored Ser Mandon Moore into the water to save Tyrion. The Lannisters and Tyrells attack Stannis's army in the rear and force him to retreat.
A Storm of Swords
In the aftermath of the Battle of the Blackwater, Ragged Jenna and Laughing Lord become pirates on the river. Bronn is rewarded for his role in the battle by being knighted as Ser Bronn of the Blackwater.
Before the port of King's Landing can be reopened, the Blackwater must be dredged of sunken ships. Three out of every four quays are damaged. A flat-bottomed ferry is one of the few ships crossing the river at the capital.
