Lodi Unified School District students this week participated in the first step to hatch salmon and return them to the Mokelumne River. Representatives from East Bay Municipal Utilities District visited more than 80 classrooms throughout the region Thursday, delivering eggs that students will nurture and monitor for the next couple of months. … [District spokeswoman Mary] Campbell said there were some warm temperatures early on during last year’s spawning season, but EBMUD staff was able to maintain cold stable water conditions to support salmon spawning, egg incubation and juvenile survival in the lower Mokelumne River. She said temperatures this season were very good, and some 10,536 Chinook salmon returned to the river.
