Question: Where does the river by the city sharing a border with Elizabeth Berg's birthplace empty into the Gulf of Mexico?

Knowledge 1: Elizabeth Berg (author)
Berg was born in Saint Paul, Minnesota, USA, and lived in Boston prior to her residence in Chicago. She studied English at the University of Minnesota, but later ended up with a nursing degree. Her writing career started when she won an essay contest in "Parents" magazine. Since her debut novel in 1993, her novels have sold in large numbers and have received several awards and nominations, even though some critics have tagged them as sentimental. She won the New England Book Awards in 1997. [SEP] Knowledge 2: Minneapolis
Minneapolis lies on both banks of the Mississippi River, just north of the river's confluence with the Minnesota River, and adjoins Saint Paul, the state's capital. The city is abundantly rich in water, with 13 lakes, wetlands, the Mississippi River, creeks and waterfalls; many connected by parkways in the Chain of Lakes and the Grand Rounds National Scenic Byway. It was once the world's flour milling capital and a hub for timber. The city and surrounding region is the primary business center between Chicago and Seattle. As of 2018, Minneapolis was home to 6 Fortune 500 companies, and the Twin Cities were the fifth-largest hub of major corporate headquarters in the United States. As an integral link to the global economy, Minneapolis is categorized as a global city. [SEP] Knowledge 3: Mississippi River
The Mississippi River has the world's fourth - largest drainage basin (``watershed ''or`` catchment''). The basin covers more than 1,245,000 square miles (3,220,000 km), including all or parts of 31 U.S. states and two Canadian provinces. The drainage basin empties into the Gulf of Mexico, part of the Atlantic Ocean. The total catchment of the Mississippi River covers nearly 40% of the landmass of the continental United States. The highest point within the watershed is also the highest point of the Rocky Mountains, Mount Elbert at 14,440 feet (4,400 m). [SEP] Knowledge 4: Gulf of Mexico
The Gulf of Mexico formed approximately 300 million years ago as a result of plate tectonics. The Gulf of Mexico basin is roughly oval and is approximately 810 nautical miles (1,500 km; 930 mi) wide and floored by sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Florida Straits between the U.S. and Cuba, and with the Caribbean Sea (with which it forms the American Mediterranean Sea) via the Yucatán Channel between Mexico and Cuba. With the narrow connection to the Atlantic, the Gulf experiences very small tidal ranges. The size of the Gulf basin is approximately 1.6 million km (615,000 sq mi). Almost half of the basin is shallow continental shelf waters. The basin contains a volume of roughly 2,500 quadrillion liters (550 quadrillion Imperial gallons, 660 quadrillion US gallons, 2.5 million km or 600,000 cu mi). The Gulf of Mexico is one of the most important offshore petroleum production regions in the world, comprising one - sixth of the United States' total production.

The Gulf of Mexico (Spanish: Golfo de México) is an ocean basin and a marginal sea of the Atlantic Ocean,  largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast", in comparison with the U.S. Atlantic and Pacific coasts.
