Willard swimming pool is now filled with mud FacebookTwitteremailPrint By Frances DinkelspielJan. 5, 2011, 11:45 a.m.Oct. 31, 6:31 p.m. The city of Berkeley has filled Willard pool with dirt. The pool was shut down June 30, 2010 after voters rejected Measure C, which would have imposed a special tax to help maintain Berkeley’s four public swimming pools. Don’t make the mistake of trying to dive in. Frances Dinkelspiel is co-founder and executive editor of Berkeleyside. Email: email@example.com.
