History of Dierkes Lake

Dierkes Lake has a fascinating backstory. It was named after John Dierke, a German immigrant who arrived in Idaho in 1907. While working for Idaho Power, he discovered the canyon’s creek and began planting orchards of apples, cherries, and peaches nearby.

However, his farming efforts were short-lived—irrigation caused the local water table to rise, eventually flooding the land. Legend has it that Dierke had to pick his last crops by boat! In 1969, the lake was sold to the city of Twin Falls and opened for public recreation.
