MILFORD STATE PARK, KS (KDWP)- Are cardboard boats seaworthy? The question will be answered Aug. 18th at the Extreme Outdoor Water Festival at Milford State Park. Activities will take place at the South Boat ramp from 10 a.m. until 4 p.m. and include a triathlon, games for kids, courtesy boat inspections, canoe and kayak paddling, and a "Float Your Boat" race.

In the Float Your Boat race, teams will build cardboard boats and see if they will not only float, but carry a crew. Age categories for two-person teams are seven through nine, plus one person older than 18; 10 through 12, plus one person older than 18; 13 through 17; 19 and older.

Construction of boats is simple. The only materials allowed are cardboard, which may be waxed, and packing and/or duct tape. Teams will be required to negotiate a set course using only oars for power. All team members will be required to wear a life vest.

“We expect a variety of designs and building techniques," says Cynthia Dierks of the Milford Lake U.S. Army Corps of Engineers. "Every team that enters will win a prize, with the top two finishers in each category winning trophies and cash. We do not have an entry fee, so we’re hoping for lots of entries.”

The cardboard boat race will take place from 1 p.m. to 3 p.m. at the South Boat Ramp area. Boats and teams need to be on site by noon for registration and inspection. For additional information and details, visit the Junction City Chamber of Commerce website.
