First Knoll Tank

First Knoll Tank is a reservoir in Navajo County, Arizona and covers about 0.1 acres, reaches about 4.4 feet at its deepest point and holds roughly 0.2 acre-feet.

First Knoll Tank is small water, so a careful lap around the bank can show most of the useful cover. With little deep water in First Knoll Tank, weeds, wind, and water color can matter more than depth alone.

Fish and Baits

When the bite is slow on First Knoll Tank, the fish mix here is not confirmed, so check fresh local information before choosing a target or keeping a catch.

For a first pass on First Knoll 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

A direct approach on First Knoll Tank works like this: start where two things meet: weeds and open water, rock and mud, a point and a drop, or clear water and dirty water; fish that edge at more than one depth before leaving it.

Season by Season

At First Knoll Tank, early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again.

A Simple Tackle Plan

During the first hour on First Knoll 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.

On First Knoll 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.
