Kīlauea is the youngest and most active volcano on the Island of Hawai'i.
The lake, which appeared after the eruptions in 2018, is expected to reach up to 230 feet in depth.
In total, the lake contains around 125 million gallons of water and is gradually growing larger by the day.
The USGS has released images of the newly-formed lake inside the Halema'uma'u crater.
The body of water—which is rusty brown in color due to chemical reactions —measures up to 100 feet deep and has an area of roughly five football fields.
Water has been steadily rising in the pool since it was discovered at the end of July.
The eruption started in April and continued through August, as magma drained and the caldera collapsed.
It reportedly registered a magnitude of about 4.3.
It's headed for the boat ramp in Isaac Hale Park.

Coagulated volcanic spatter has created a 200 feet cone that should last for thousands of years.
Several new fissures are oozing lava—and there was another explosion at Kilauea's summit.
Volcanic ash continued to sputter from a volcano on Hawaii's Big Island, raising health concerns about exposure to the toxic plumes.
