(Kevin Fujii\/Civil Beat\/2024)<\/p>\n<p>The state Department of Land and Natural Resources issued four deficiency notices to Dole between 2009 and 2020 for failing to adhere to dam safety regulations. Then in 2021, the state land board issued a $20,000 fine to Dole for failing to address safety concerns with the dam and its spillway.\u00a0<\/p>\n<p>A recent safety report notes that the spillway is \u201cundersized and deteriorated\u201d and notes that there are stability issues with the reservoir\u2019s embankment.<\/p>\n<p>The deficiency notices and fines were also issued for failing to keep the water level below a 65-foot restriction set by the state.<\/p>\n<p>Dole General Manager Dan Nellis said the spillway was built to accommodate milder storms, not today\u2019s stronger varieties.<\/p>\n<p>\u201cIt\u2019s a good, strong dam,\u201d Nellis said. \u201cIt\u2019s very functional.\u201d<\/p>\n<p>The state moved to acquire the reservoir and accompanying irrigation system in 2023. That year, Dole also asked the land board to suspend its fines and remediation plan while it worked out a deal to transfer the reservoir to the state. The land board rejected that proposal and kept the fines in place. But the state has yet to close on the acquisition of the dam.<\/p>\n<p>It\u2019s still unclear what stage of the acquisition the state is in, though the purchase of Sustainable Hawai\u02bbi\u2019s 143-acre portion of the dam and spillway was in escrow in January this year. The remainder of the system, owned by Dole, was not complete at that time.<\/p>\n<p>The price tag for the system and safety improvements is now over $50 million.<\/p>\n<p>The state planned for the Department of Land and Natural Resources to take over Lake Wilson, with the remaining infrastructure to be owned by the Agribusiness Development Corp. once refurbished.<\/p>\n<p>The state-owned corporation anticipated the transaction would be complete by June this year but was \u201cahead of schedule,\u201d executive director Wendy Gady told Civil Beat in January.<\/p>\n<p>Reporters Caitlin Thompson and Thomas Heaton contributed to this report. <\/p>\n<p>          <img decoding=\"async\" class=\"aside-logo\" src=\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/07\/logo10.png\" alt=\"Civil Beat\"\/><\/p>\n<p>            Sign up for our FREE morning newsletter and face each day more informed.<\/p>\n<p>                  Sign Up<\/p>\n<p>\n                Sorry.
