Upper Tank

The 0.7-acre Upper Tank in Pinal County is a reservoir in Arizona and covers about 0.7 acres, reaches about 8.1 feet at its deepest point and holds roughly 2.6 acre-feet.

The small size of Upper Tank makes quiet casts and short moves more useful than carrying a pile of tackle. With little deep water in Upper Tank, weeds, wind, and water color can matter more than depth alone.

Fish and Baits

At Upper Tank, the fish mix here is not confirmed, so check fresh local information before choosing a target or keeping a catch.

At Upper Tank, begin with one slow bottom presentation and one moving bait, then let bites show whether fish are holding close to cover or roaming open water.

How to Read the Water

At Upper Tank, use wind as a clue; a light push can carry food toward a bank, but hard wind may muddy it, so look for a clean edge near a point or protected pocket.

Season by Season

At Upper Tank, shallow water is worth a careful look in spring and again during fall; bright summer days favor shade, weeds, or deeper breaks; under ice, a small depth change can be more useful than a long move.

A Simple Tackle Plan

At Upper Tank, a medium spinning rod, 8-pound line, a small box of jigs, a few crankbaits, and a simple bottom rig cover most situations; change depth or speed before changing every piece of tackle.

At Upper Tank, record the wind, water color, productive depth, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
