The Haw River Watch will host a Macro-Micro Workshop on Saturday, March 29 from 10 a.m. to 2 p.m. at Bynum Beach. River Watch volunteers will teach those interested about collecting and inspecting water samples for microscopic creatures (with an interlude for lunch). Examining the creatures can provide information about water quality. RSVP and get more information from Cynthia Crossen at 967-2500 or riverwatch@hawriver.org
