Dams like Plughole create enchanting water displays

According to the Solano County Water Authority, Monticello Dam spillway in Northern California was turned on for the first time on February 4, 2019 since 2019.

Its release system is known as the “hole of glory” style, as a result of a Pulgor-like effect as the water flows.

Officials say the system was used because the dam was too narrow for the spillway of traditional releases.
