A study is being considered to assess the risks at a Lake Wanahoo spillway where an 11-year-old boy drowned last month.
Olsson Associates, the Nebraska engineering company that designed the spillway, will provide the NRD with a list of consulting firms that could perform a risk-assessment study, said John Miyoshi, the general manager of the Lower Platte North Natural Resources District.
Currently, there is no fencing around the spillway that releases water into Sand Creek from the 662-acre Lake Wanahoo, about a mile north of Wahoo, Neb.
“Olsson did not recommend any changes in the area below the dam,” Miyoshi said. “They are very concerned about placing any permanent structures that could change the hydraulics of the (lake) discharge.”
Bayden Martinez of Wahoo drowned in the spillway June 12 after his leg became caught in a 12-inch drain. The NRD erected warning signs after the boy's death.
The NRD board also has voted to accept one $550,000 payment from Saunders County and Wahoo to settle a dispute over the final costs of Lake Wanahoo. The NRD had sought $648,000 from each of its partners to complete the $33.5 million flood-control project.
Wahoo Mayor Jerry Johnson said the payment will “complete all financial obligations of the interlocal agreement” that the three entities signed in 1998. Johnson said he is the fourth Wahoo mayor to be associated with the project.
“It's great to have it behind us,” Johnson said.
