River Algae Creates Distinctive Patterns

SOLVANG, CA - MAY 20: An thick layer of algae forms distinctive shapes, clumps, and patterns along the Santa Ynez River west of Cachuma Lake on May 20, 2019, in Solvang, California. With the abundance of rain this year, the river water flow has been running consistently through the spring, but the river is now beginning to seasonally dry up, creating areas of algae.
