With the Martin Luther King weekend holiday approaching, a soccer tournament expected to draw 2,000 participants will go forward. So will a half-marathon with 1,000 runners.

But soccer participants may have to take some detours to the fields, and the half-marathon route has changed.

"Everything is open for business," said Pam Hilton of the St. George Visitors and Convention Bureau. "There is no damage to the hotels. The sun is out today, which is good."

Marc Mortensen, assistant to the city manager, said flood waters destroyed Blake Memorial, Bloomington, Clark Corner and Mathis parks and that three-quarters of Tonaquints Park was gone. Two miles of St. George's popular river trail system had been destroyed and another seven were covered by mud and water. Many of the parks were built along flood plains.

Mortensen estimated damage to park facilities at more than $3 million.

"Some are unbuildable now," Mortensen said. "There is no ground. It is all in the river."

The main road into Zion Canyon was briefly closed Tuesday because of mudslides but it was open Wednesday, said park spokesman David Eaker. Slides have kept the park's Kolob Canyon road closed.

Facilities at Quail Creek and Sand Hollow reservoirs and at Snow Canyon State Park were undamaged, said Bruce Hamilton of the Utah Division of Parks and Recreation. Division officials could not reach Gunlock Reservoir to assess the damage.

The U.S. Bureau of Land Management's Dixie Red Cliffs Campground sustained no damage but has been closed. The BLM's Baker Reservoir campground remained open and unaffected. The BLM warned against travel on backcountry roads and trails in southwestern Utah because many had been washed out.

St. George golf courses affected by the flooding included city-owned Southgate and Sunbrook and privately-owned Sun River.

The Santa Clara River flooded the front nine holes of the Southgate course. It will take six months to repair those holes but the back nine will remain open, said Dave Terry, the city's golf director.

At Sunbrook, the river damaged 1 1/2 holes on the Woodbridge nine and wiped out a bridge leading to the Black Rock back nine.

"The second hole [at Sunbrook] looked like the Colorado River," said Terry. "It is going to take us until May until we have it put back together again."

Sun River's Jim Finney said the front nine of that course was severely damaged by flooding. Crews were working to get the 17th and 18th holes cleared so the back nine would be usable.

Utah Division of Wildlife Resources biologist Dale Hepworth said it will take a while to assess the effect of the flooding on Quail Creek, Gunlock, and Upper and Lower Enterprise reservoirs, which were recently restocked with fish.

"We have no idea what will happen to those fish," Hepworth said.
