The Hawaii Board of Land and Natural Resources voted to approve the state's acquisition of the Wahiawa Reservoir, also known as Lake Wilson, following a recent scare over the dam's potential failure. Officials say the move could help manage flood risks and allow upgrades to meet modern safety standards, though the deal is not yet finalized.

Why it matters

The Wahiawa Reservoir is a critical water resource that helps recharge the island's groundwater aquifer, provides irrigation for agriculture, and offers recreational opportunities for the local community. Acquiring the reservoir will allow the state to better maintain the aging infrastructure and mitigate flood risks, ensuring the long-term sustainability of this important asset.

The details

Last week, city officials urged residents downstream to evacuate after the dam was considered at risk of failure. The Board of Land and Natural Resources voted to approve the state's acquisition of the reservoir, which is currently owned by Dole Food Company. One of the first priorities would be upgrading the reservoir's spillway to current safety standards. The proposal now goes to the Agribusiness Development Corporation Board of Directors for final approval before the property officially transfers to the state.
