"Tourism is one of the biggest income markets within the U.S.," Morris said. "It severely impacts a lot of communities that rely on people visiting the country."
Some of the state's national parks have a combination of public and private owners in different regions.
The Mississippi National River and Recreation Area in the Twin Cities, for example, would remain open, as much of it is owned by state and private partners, said park superintendent Paul Labovitz. Its federal offices and programs, including the visitor's center, would close, he said. Other parks, like the Pipestone National Monument in Pipestone, would close completely.
In previous shutdowns, furloughed workers were reimbursed for time lost, Morris said. It's unclear whether that will happen this time.
On Wednesday, a letter to House Speaker John Boehner from 16 U.S. senators, including Minnesota's Amy Klobuchar, urged him to find another solution rather than a government shutdown.
"A government shutdown at this time would only serve as a counterproductive attack on our economic recovery," the letter said.
The letter went on to say that a bipartisan deal is possible and a shutdown would only punish citizens for political gain.
U.S. Sen. Al Franken said in a statement that the last government shutdown caused significant hardship for Minnesotans. He said another shutdown should be avoided at all costs.
"There's no question that we need to cut spending and reduce our deficit, but we must do it in a responsible way that helps create jobs — and that effort does not include shutting down the government," Franken said.
