SCOFIELD — The hope was that given the opportunity to catch and keep twice the regular limit, fishermen would return to what was once one of Utah's most popular fishing holes.

It appears more fish wasn't the answer. Now officials are looking to see if bigger fish will be more enticing.

The statewide limit on trout is four. New regulations this year bumped the limit to eight at Scofield.

The reason?

A drop in the number of people fishing there. The reservoir is one of the most productive and offers some of the best fishing, but pressure has dropped significantly over the past 20 years.

In 1986, anglers spent almost 347,000 hours fishing at Scofield. The number dropped to just under 115,000 hours in 2005, a drop of 67 percent.

Understandably, fewer fishermen has resulted in fewer fish being caught. In 1986, anglers caught more than 252,000 trout. By 2005, that number had fallen to less than 36,000.

A random survey this year found there were some avid fishermen who didn't even know where Scofield was.

It is roughly 100 miles from Salt Lake City en route to Price by way of Spanish Fork Canyon. Strawberry is 75 miles away.

Before making the change in the limit, said Paul Birdsey, regional fisheries biologist for the Utah Division of Wildlife Resources, a survey was conducted and the results were split — half wanted an increase in the limit and half wanted a decrease.

"We opted for the increase," he said.

Funding only allowed staff to run creel surveys for four months. In question is whether those surveys hit peak fishing periods.

"Which is why we're going to increase our efforts to see if we're getting the most accurate data," said Birdsey.

One concern, said Roger Wilson, cold-water fisheries coordinator for the DWR, is an increase in the number of chubs showing up in Scofield.

The first reappearance of chubs was seen in gillnet surveys in 2005. In 2006 there were 19 netted and 54 this year, which accounted to about 30 percent of the fish caught in the nets.

The solution to the chub problem at Strawberry Reservoir was to plant a predator fish, the Bear Lake cutthroat. The plan for Scofield is to plant tiger trout, also a predator fish.

In recent weeks, anglers have been catching 18- to 20-inch tiger trout.

The increase in chubs, however, has caused a change in planting plans. A couple of weeks ago, 120,000 of the 5-inch tiger trout were planted in Scofield. In the spring, 450,000 of the 3-inch rainbow were planted, and in the fall another 100,000 of the 7-inch fish.
