Big Tank in Sierra County is a reservoir in New Mexico and covers about 1 acres, reaches about 3 feet at its deepest point and holds roughly 1.6 acre-feet.

When choosing a bank on Big Tank, this water is small water, so a careful lap around the bank can show most of the useful cover. Before changing spots on Big Tank, this water is shallow, so weeds, wind, and water color can matter more than depth alone.

Fish and Baits

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

At Big Tank in Sierra County, 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 focused trip to Big Tank begins this way: do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.

Season by Season

When the bite is slow on Big Tank, spring runoff can add color and pull fish toward fresh water; green weeds and the first drop become stronger summer targets; in fall, follow bait toward points and shallow flats, while winter rewards a slower search.

A Simple Tackle Plan

At Big Tank in Sierra County, 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 Big Tank in Sierra County, 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.
