A half-covered sky tonight, with air barely moving and pressure ticking upward. Expect most activity at Arrowhead Reservoir around points and the old channel edges. The numbers single out the morning. Fish confidently and change only when the bites stop. Shortening days concentrate the feeding into fewer hours.

Arrowhead Reservoir is listed under Weld County, Colorado. It sits in open valley. About 23 acres of surface, which puts the far bank inside easy sight. It is low-lying compared with other Colorado water we list. The nearest town is Evans, 3.5 miles away. La Salle lies 3.5 miles off, Greeley another 4.2 miles. This one is safely inside the county line.
There is no published depth for this one, so start shallow and work out. A reservoir gives you a hard edge, a shelf, and not much else. Look for where the old bank line still shows under the surface. Open biodiversity records for Weld County list white sucker, common carp, green sunfish and longnose sucker. County data is a starting point rather than a guarantee. Work Arrowhead Reservoir in sections rather than trying to cover it.
The warmest month averages 72°F, the coldest about 26°F. A lid forms in a hard winter only. In milder years the edges alone go, and the middle never sets. The hot months push the fishing to dawn and dusk. That is the shape of the year on Arrowhead Reservoir. Long dry spells drop the level and concentrate them.
We hold no note on access for this one. Recorded parking is half a mile off, far enough to travel light. Carp respond to sweetcorn or boilies fished patiently on the bottom near feeding areas. Some banks are open only from a marked point. Access can change hands, so last year's answer may not hold. Should this one be busy, Rehmer Lake is 1.4 miles off. Confirm before you fish Arrowhead Reservoir.
