A team of state geologists and dam-safety experts examined the failed Quail Creek dike Tuesday, but no decision has been made about whether to drill for underground geology tests.

Deputy sheriffs and state parks officials were stationed near the dike on Wednesday to keep people from dangerous areas."They've requested people stay off the dike itself, because it's unstable near the edge where the water has run through," said Dave Morrow, a ranger stationed at the state park at Quail Creek Reservoir. Spectators also are required to stay out of the cut itself, he said.

The state team Tuesday included Richard B. Hall, in charge of Utah Division of Water Rights dam safety department, plus geologists from the Division of Water Rights and the Division of Water Resources and a state photographer. Larry Anderson, director of the Division of Water Resources, was scheduled to arrive Wednesday.

A blue-ribbon task force of three or four experts is expected to be formed this week to study the dike's collapse and report on the cause. That panel will decide whether drilling for samples will be required.

Meanwhile, no federal dam safety experts are on site.

"We asked them not to come in. We don't want the area disturbed until state officials can make their studies," said Dee Hansen, director of the Utah Department of Natural Resources. Hansen was interviewed by telephone in Salt Lake City.

Hansen said one reason he would like to limit the number of people around the dam is, "it's fairly dangerous now with those vertical banks."
