This lake was created at the behest of Sir Damien Catharn’s father, to control Spring flooding issues where the Eldercut River joined the Churnwash. The high, swift waters would sweep way the crude docks at the base of the ore sluice where the miners would load rafts bound for Tilburne.
The small river eels native to the river get trapped in the man-made lake and grow fat. Once a year, residents of Tilburne come to Eelrock Lack and capture the eels in nets. This is a fairly big part of the Autumn harvest.
