Tues., Apr. 18, Free Bay Currents talk, "How Rivers and Lakes Work"

Join us for a fascinating and timely evening as Dr. Vince Resh of UC Berkeley vividly explains the interplay of chemistry, geology, hydrology, and biology in our water bodies. Why, for example, can many plants and animals live in either lakes or streams but not both?

Dr. Resh has taught at UC Berkeley since 1975, in a career that has included restoration of Strawberry Creek on the Berkeley campus, working with international agencies on West African river blindness, and studying effects of Chinese dams in Southeast Asia. He remains involved in water policy, and will also talk about the role of monitoring water quality.

Bay Currents talks are second or third Tuesdays, fall-spring, at St. Alban's Parish Hall, 1501 Washington (at Curtis). Talks are free, but seating is limited. Refreshments 7 PM, talks 7:30 PM. Download full spring schedule here. Sign up for notification here.
