Today's Fishing Report

Generated this morning from live readings: gauge, weather model, sun and moon. A fresh report is published here every morning.

4/5Good. Solid day ahead.Stable-to-falling pressure and workable wind line things up.

Lake Tschida is in transition: bait on the move and predators following. The nearest gauge is running 12 cfs, on the rise. Today brings clear skies, wind SSE around 16 mph, falling pressure near 1001 hPa and a high of 77. Water sits around 55 F for the season (estimated). With the waxing gibbous, the solunar majors run 9:23 AM-11:23 AM and 9:54 PM-11:54 PM: the windows to build the day around.

The plan, species by species

WalleyeExcellent

Spring: post-spawn fish scatter and can be slow for a couple of weeks. Fall: one of the best windows, with minnows on jigs and three-way rigs as the water cools toward ice-up.

Northern pikeExcellent

The best band for pike: right after ice-out they move into flooded vegetated shallows to spawn, and they feed actively again as the water cools in fall.

Largemouth bassExcellent

In spring, pre-spawn bass push shallow as the water climbs through the mid-50s; in fall they feed actively until the water cools into the low 50s, then drop back toward deeper structure.

Smallmouth bassExcellent

Spring pre-spawn and fall: Iowa DNR notes the larger bass come up to shallow structure, where a shallow-running minnow bait or a spinnerbait just under the surface works.

Catfish (blue, channel)Excellent

In spring after ice-out, Iowa finds channel cats feeding on winter-killed shad on the shallow, warmer mudflats at the upper ends of reservoirs; cut bait on the bottom works there.

Yellow perchExcellent

Spring and fall: perch hold shallower and, by Michigan DNR's account, feed through the day, so shoreline weed edges, flats and the shallows near spawning areas are worth searching.

MuskellungeExcellent

This band covers the spring spawn, which in Wisconsin runs at 49-60°F; spawning muskies eat little and rarely chase lures, Wisconsin DNR says. After the spawn, and again as fall water cools, work large lures along weed edges and structure.

White bassGood

The spring run happens in this band: tributaries, shoals and the upper ends of reservoirs as the water reaches about 55°F.

CrappieGood

Pre-spawn fish move toward shallow coves, and Iowa DNR points to wading as an effective way to reach them in spring; minnows or small jigs under a float.

Tomorrow: Cooler at 55 F. The solunar majors shift about 50 minutes later.Next report: Sat, Oct 24, 6:30 AMHow this report is made →

Species guide

The species that matter on Lake Tschida: seasons, structure and how to fish each one. Today's ratings live in the report above.

Walleye illustration

Walleye

Best: spring and late fall, around dawn, dusk and night

A cool-water perch of large lakes, reservoirs and rivers whose reflective eyes are built for low light, so it feeds most at night and in murky water. The Missouri Department of Conservation ranks it among the continent's most important freshwater game fish. Spring: post-spawn fish scatter and can be slow for a couple of weeks. Fall: one of the best windows, with minnows on jigs and three-way rigs as the water cools toward ice-up.

White bass illustration

White bass

Best: the spring run up the tributaries, then summer surface schools

A silvery temperate bass of rivers and large reservoirs, also called sand bass, that schools in open water after shad and runs up tributaries to spawn in early spring. The spring run happens in this band: tributaries, shoals and the upper ends of reservoirs as the water reaches about 55°F.

Northern pike illustration

Northern pike

Best: cool water, from ice-out through spring, in fall and under the ice

A long, duck-billed predator of weedy lakes, slow rivers and backwaters that ambushes fish from vegetation. Wisconsin DNR points out that, unlike most of the state's common game fish, pike do their best feeding in cool water. The best band for pike: right after ice-out they move into flooded vegetated shallows to spawn, and they feed actively again as the water cools in fall.

Crappie illustration

Crappie

Best: the spring spawn; summer around docks, brush and the thermocline

Two slab-sided panfish, the white crappie and the black crappie, that gather around submerged timber, brush piles, docks and bridge pilings in lakes, reservoirs and slow river backwaters. Texas Parks and Wildlife counts crappie as the state's most popular panfish. Pre-spawn fish move toward shallow coves, and Iowa DNR points to wading as an effective way to reach them in spring; minnows or small jigs under a float.

Largemouth bass illustration

Largemouth bass

Best: the spring pre-spawn and the fall feed

A warm-water sunfish of lakes, reservoirs, ponds and slow river backwaters that holds tight to cover: weeds, logs, rock ledges and docks. In Texas, TPWD surveys rank it "by far" the freshwater fish anglers most want to catch. In spring, pre-spawn bass push shallow as the water climbs through the mid-50s; in fall they feed actively until the water cools into the low 50s, then drop back toward deeper structure.

Smallmouth bass illustration

Smallmouth bass

Best: spring and fall, when bigger fish come shallow

A bronze-brown black bass of clear, cool streams and rocky lakes, with dark vertical bars instead of a side stripe. Michigan DNR says its southeastern coast, from Port Huron to Lake Erie, is known nationally for both the size and the number of its smallmouth. Spring pre-spawn and fall: Iowa DNR notes the larger bass come up to shallow structure, where a shallow-running minnow bait or a spinnerbait just under the surface works.

Catfish (blue, channel) illustration

Catfish (blue, channel)

Year-round, best at dusk and after dark

Three big catfish share most of the country's rivers and reservoirs: the channel catfish, the most widespread; the blue catfish, the largest; and the flathead, which hunts live fish. All feed mostly on or near the bottom. In spring after ice-out, Iowa finds channel cats feeding on winter-killed shad on the shallow, warmer mudflats at the upper ends of reservoirs; cut bait on the bottom works there.

Yellow perch illustration

Yellow perch

Caught all year, including under the ice through winter

Yellow perch are schooling panfish of the Great Lakes and northern lakes, and Michigan DNR calls them the game fish most often caught in that state. Spring and fall: perch hold shallower and, by Michigan DNR's account, feed through the day, so shoreline weed edges, flats and the shallows near spawning areas are worth searching.

Muskellunge illustration

Muskellunge

Fished from late spring into late fall where seasons allow

Muskellunge are solitary, fish-eating ambush predators of the pike family, holding in weed beds and other cover in lakes and rivers of the Great Lakes, upper Mississippi and Ohio basins. This band covers the spring spawn, which in Wisconsin runs at 49-60°F; spawning muskies eat little and rarely chase lures, Wisconsin DNR says. After the spawn, and again as fall water cools, work large lures along weed edges and structure.

Ten Reclamation boat ramps (13 lanes), seven campgrounds and a swimming beach; 15 miles south of Glen Ullin on Highway 49. Reclamation, Bismarck: (701) 250-4592.

About this water

3,397-acre Reclamation reservoir on the Heart River, Grant County, North Dakota.

Fishing Lake Tschida: the full guide

Heart Butte Reservoir

Reclamation manages Heart Butte Reservoir, known locally as Lake Tschida, as part of the Pick-Sloan Missouri Basin Program. Its recreation page lists 3,397 water-surface acres and 55 miles of shoreline, 15 miles south of Glen Ullin on Highway 49.

What Reclamation lists

The species on Reclamation's page are crappie, walleye, catfish, perch, white bass, pike, bluegill, and largemouth and smallmouth bass.

Facilities

Reclamation counts 10 boat ramps with 13 lanes, seven campgrounds with 420 sites, 17 picnic shelters and one swimming beach, and its fee table lists no entrance, camping or launch fees. The area is open around the clock; a bait, food and gas concession runs from Memorial Day through Labor Day.

North Dakota limits

No Heart Butte exception appears in North Dakota's 2026-28 fishing proclamation, so statewide limits apply: five walleye, sauger and saugeye combined; five northern pike; 20 yellow perch; 10 crappie; and, because the lake lies west of ND Highway 1, 20 channel catfish a day. Unoccupied fish houses must be off the ice from midnight March 15 until ice-out.

How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written text was drafted with AI assistance from the official pages listed above, and its facts were checked against those pages by automated verification on October 8, 2026; anything that could not be verified was taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Errors are published in the verification log; the full policy is in the editorial policy.
