Wengwater

The Wengwater was a tributary of Lake Weng in Amn.

Description
The river was fast and had dangerous rapids. Each year, it flooded, which left small ponds north of the town of Amnwater.

Geography
The Wengwater began in the Cloud Peaks and flowed past Amnwater until it poured into Lake Weng from the east.

History
Every few years, someone tried to run the rapids of the Wengwater in a feat of daring, but as of 1370 DR, no one in 300 years had successfully navigated them.
