Used to cruise Powell and look for boils. Only got one or two fish then school would submerge for a while. Had to chase them to get more.
As for eating, I brought many home. Now days it seems that mercury warnings are everywhere. Here is Powell's:
Location: Lake Powell, Coconino County (Arizona) Kane and San Juan Counties (Utah) from Dangling Rope Marina south to the Glen Canyon Dam.
Pollutant: Mercury
Fish Species: Striped bass
Advisory: The State of Utah recommends that pregnant women and children under six should limit their consumption of Striped bass to one 4- ounce meal per month. Women of childbearing age and children between the ages of six and sixteen should limit their consumption of Striped bass to three 8-ounce meals per month. Adult women past childbearing age and men older than 16 should limit their consumption of Striped bass to nine 8-ounce meals per month
