Mantua Reservoir, the go-to watersports and fishing spot just east of Brigham City, is suddenly in the spotlight as a potential new Utah state park. State and local officials have already walked the shoreline together and opened early talks, but there is no deal, no timeline and plenty of questions about recreation access, water operations and how much say locals will actually have.
State and local leaders have already toured the site
Utah State Parks staff and Mantua leaders coordinated winter site visits, including a January 30 tour of Mantua Reservoir and a February 6 visit to nearby Echo, as the agency starts gathering local input, according to the Town of Mantua newsletter. Chris Haramoto, a deputy director with Utah State Parks, is among the officials involved in those conversations.
The town newsletter characterizes the state park proposal as "in the works" and tells residents to keep an eye out for public meetings and comment periods, signaling that the process is still very much in the sounding-things-out stage.
Funding language is already in the governor’s proposal
Language to study and start building out a possible Mantua state park is tucked into the Gov. Spencer Cox’s proposed budget. The money would come from fees already collected by the parks division rather than new general-fund spending, according to KSL.
That budget note is not a green light on its own. Lawmakers would still have to approve the spending and formally designate Mantua Reservoir as a state park before any shovels hit the ground. State Parks officials have told local leaders they are thinking in phases so any future improvements can be timed around water operations and safety constraints.
Water, safety and storage matter for any park plan
Mantua Reservoir is a government-owned facility that was completed in 1961. At full capacity, it holds roughly 10,450 acre-feet of water, with a normal storage level around 7,560 acre-feet, according to data compiled by Snoflo.
The dam and reservoir are regulated by state water authorities, and the Utah Department of Environmental Quality has issued recent harmful-algal-bloom advisories for Mantua, underscoring that public health monitoring is already part of the picture and would remain so under any park arrangement, as noted by Utah DEQ. Those infrastructure and health realities are a big reason officials say any park planning has to move carefully, not quickly.
Local leaders say they want community input
Utah State Parks says it is currently "engaging stakeholders" as it evaluates the Mantua idea, and a parks spokesperson told Cache Valley Daily that "there is no timeline and no agreements have been drafted." Brigham City Mayor D.J. Bott told the outlet he supports the proposal at this time, while Mantua Mayor Annette Ash has stressed that the idea will not move forward without community backing.
The town newsletter echoes that stance, framing the recent tours as early-stage outreach and urging residents to show up for upcoming meetings and weigh in before anything becomes official.
What comes next for the proposal
If the concept moves ahead, the Utah Legislature would need to formally designate Mantua Reservoir as a state park and authorize the use of collected park fees for any buildout, a step outlined in reporting on the governor’s budget by KSL.
Town officials say public meetings and additional studies are the next likely steps. If lawmakers sign on and local stakeholders fall in line, any new facilities would probably be rolled out in phases so recreational upgrades do not interfere with water supplies or ongoing health monitoring. For now, Mantua’s state park talk is still in listening mode while state and local leaders sort through the details.
