Aquatic biologist Brandon Watson loads a box of the chemical 2,4-D onto a boat equipped with outriggers designed to distribute the chemical into the water to kill Eurasian milfoil, an invasive aquatic weed, during a control effort at Newman Lake.

A technician pours the chemical 2,4-D into a spray tank on Tuesday at Newman Lake. Boaters and swimmers were asked to stay off the lake for a few days this week to prevent disturbances that would reduce the herbicide’s effectiveness.
