Progress continues on the new Marshfield Aquatic Center By Liz Holbrook MARSHFIELD, WI (WSAU-WDLB) –Marshfield's new replacement for Hefko Pool is taking shape. During a tour of the project on Thursday, city Parks and Recreation Director Justin Casperson told a small group of business and community leaders the work on the Vandehey Waters Outdoor Aquatic Center is on time and on budget so far. “They’re finishing up the bathhouse right now. They want to get that sealed up before Mother Nature takes hold, snow starts falling, and temperatures really start dropping. “We’re lucky, fortunate, and thankful that we’ve had favorable temperatures so they’re able to work a little quickly. The pool vessels themselves, they’ve done most of the flatwork and now they’re starting to do the walls on all the vessels themselves. We just hope Mother Nature will keep cooperating with us. I know probably Rotary Winter Wonderland would like some snow but the Vandehey Aquatic Center would like sunshine and warm weather.”
