Kevin Swift, owner of Swift Water Design, has dedicated his career to restoring meadows in the Sierra Nevada — specifically one a few miles above Shaver Lake called the Lower Grouse Meadow, which was severely affected by the 2020 Creek Fire. … Swift and his team managed to restore this meadow by building small dams along a stream — replicating what animals would have done. To make dams, he says, think: “dirt lasagna.”
