Utah fishing in July

High country season, early mornings on the reservoirs.

July is the high country's month. The Uintas, Boulder Mountain, the Manti-La Sal, and the Tushars are all open, the DWR is still stocking heavily (July is second only to June), and the high lakes and creeks fish all day in cool water. Low-elevation waters warm into the 70s, so reservoir trout go deep and the bite shifts to dawn, dusk, and after dark; bass, catfish, and wipers take over the warm hours. Rivers are at summer base flow and clear — hopper season starts on the freestones — and harmful-algal-bloom advisories begin showing up on the warmest reservoirs.

Where to go in July

Uinta high lakes and creeks, Boulder Mountain lakes, the upper Provo and Weber, the Green, Strawberry early and late in the day, Utah Lake and Willard Bay for catfish and wipers.

July tips

• Check HAB advisories before bringing a dog or wading a warm reservoir — they're listed on every affected water page.
• Terrestrials rule the rivers: ants, beetles, and hoppers from mid-month on.
• Brook trout in the Uintas are aggressive and plentiful; a small Royal Wulff or a black leech covers most lakes.
