The city’s carbon monoxide monitoring system will be replaced before the 2019 boating season. Tuesday, Lake Havasu City Council members approved spending $141,612 on a new system that will replace the 11 units placed in the Bridgewater Channel in 2007. The money for the system will come from the city’s contingency fund. Brian Davis, Lake Havasu City fire chief, made the request, citing five failed units by the end of the 2018 boating season. Davis said city staff planned to include the system replacement in the 2019-2020 budget but after seeing some of the units fail they decided to recommend the upgrades sooner.
