Mantua Reservoir is a reservoir in Utah, near Box Elder County.
Stocking records show that the following fish or strains were stocked here. A historical stocking does not by itself prove that a self-sustaining population remains today.
Mantua Reservoir is a reservoir in Box Elder County, Utah and covers about 514.7 acres, reaches about 24 feet at its deepest point and holds roughly 7,560 acre-feet.
The best plan at Mantua Reservoir is to choose one arm or shoreline and work it from shallow cover to the first deep break.
Mantua is a shallow northern Utah reservoir built around weeds, warm flats, points, and an old channel. It supports bass, crappie, bluegill, perch, trout, and a complicated walleye issue.
Fish weed edges for bass and bluegill, jig small baits for crappie and perch, and cast light spoons for rainbow trout.
Recent Utah proposals describe Mantua walleye as an illegal introduction and call for removing caught fish. That makes current rules essential and keeps walleye from being promoted like a managed target.
At about 24 feet deep, weed growth and water color matter more than chasing a deep hole. A clean outside weed edge can hold several species.
Channel catfish, cutthroat, and tiger trout appear in stocking history. Keep those releases separate from the confirmed warm-water list.
Fish listed for Mantua Reservoir include Black Crappie, Bluegill, Common Carp, Green Sunfish, Largemouth Bass, Smallmouth Bass, Rainbow Trout, Utah Chub, Utah Sucker, Walleye, and Yellow Perch.
A useful walleye plan on this water is to work a jig, minnow rig, or small crankbait along points and the old channel edge.
A useful yellow perch plan on this water is to keep a small jig tipped with a worm or minnow close to bottom on a shelf.
At Mantua Reservoir, try this for black crappie: fish a small jig or minnow around wood, weeds, and sharp little drops.
At Mantua Reservoir, try this for bluegill: use a small jig, worm, or tiny plastic around green weeds and protected pockets.
Other targets listed here include Smallmouth Bass, Largemouth Bass, Rainbow Trout, and Common Carp; give each one its own bait and depth instead of trying to catch everything with the same rig; make the next cast parallel to the edge.
Channel Catfish, Cutthroat Trout, and Tiger Trout have also been stocked here; that proves fish were released, but it does not promise that they are still common or easy to catch.
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; keep the lure near the depth that produced, then work each small drop before going deeper.
Here, 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 light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control; fish where rock meets mud, then save the heaviest tackle for deep cover.
At Mantua Reservoir, 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.
Keep the first hour simple: use one moving bait to find active fish, slow down with a jig or natural bait on the best edge, and repeat the same setup when two bites come from matching depth and bottom during that part of the trip; keep the bait near useful cover.
The key difference is that mantua is a shallow northern Utah reservoir built around weeds, warm flats, points, and an old channel.
For a first trip, fish weed edges for bass and bluegill, jig small baits for crappie and perch, and cast light spoons for rainbow trout.
Do not let the largest depth or an old stocking note replace current water conditions, food, and the confirmed fish list; start with the cover closest to deep water, then write down the productive depth.
