Here is the Upper Peninsula fishing report for this week:

Marquette — This past week saw a large increase in fish almost everywhere. Steelhead were reported going back up the rivers. There were a few more coho salmon caught along the break wall and near the Shiras Power plant. A few brown trout and steelhead were also caught on the break wall this week, and more were expected as it warmed up.

The Carp River produced a few more steelheads. If fishing near the mouth was not productive, anglers moved farther up the river, where a few fish were reported past the prison and near the Marquette Mountain area.

The Chocolay River was slow again this past week due to high water levels and flooding. In the bay, the coho salmon bite improved significantly, with the average catch per boat increasing from three the previous week to six per boat. There was also an increase in fish size, including a 25-inch coho salmon caught while trolling. Most fish were small earlier in the season, but larger fish appeared to move in from deeper water as the bay warmed. Many brown trout were caught while trolling around the mouth of the Chocolay River as well.

Au Train — The Brownstone boat launch was accessible. Coho salmon and steelhead started staging in the river, and the Au Train River mouth had reopened and was fishable again. Many coho salmon were caught there this past week by surf anglers. The fish seen since March were all caught near the mouth of the river along the ice cliffs. Most were caught using jigs with wax worms, floating spawn eggs, or casting spoons.

Munising — Low fishing activity this past week, a lot of ice was still in the bay as anglers waited for it to push out for open water season. Anglers reported little success at the Anna River mouth with only a few coho salmon being caught.

Grand Marais — The boat launch was opened, and the bay still had some ice around in West Bay and near the Sucker River Mouth. Anglers reported catching a few coho salmon off the breakwall with spawn working the best.

Manistique — The river this week was extremely high and fast. Most anglers elected to delay their efforts for when the river is lower. The fishing was not successful and the river was dangerous.Little Bay de Noc — Angling pressure was very low. Docks had been put in at the Escanaba River. Other docks will be put in as the remaining ice melts.

Keweenaw Bay — The docks remained out of the water. Shore anglers reported the occasional catch of coho salmon and steelhead, although fishing was slow.

Traverse Bay/Portage Entry — The docks remained out of the water at the Traverse Bay and South Portage Entry boat launches. However, anglers were able to launch. Shore anglers reported a slow bite.

Ontonagon River — Docks remained out of the water at the Ontonagon Marina boat launch. Angling efforts on the river were very low. River conditions slightly improved over the past week, but low temperatures seemed to be keeping anglers off the water.

Ontonagon/Silver City/Union Bay — Docks remained out of the water in Ontonagon and Silver City. Access to Union Bay was open as the gate into the Porcupine Mountains boat launch was opened for the season. The fish cleaning station located at the Ontonagon Marina also remained closed for the winter season. Fishing efforts from these ports have been very low. Reports suggest that coho salmon were caught in low numbers.

Black River Harbor — Amenities at the harbor remained closed from the winter off season. Fishing efforts remained low over the past week. Some anglers reported catching coho salmon in low numbers from the harbor breakwalls.

St. Ignace — The Carp River mouth site was accessible. Carp River temperatures fluctuated between 36 and 38 degrees, while Nunns Creek ranged between 38 and 40 degrees. McDonald’s Rapids, the Carp River campground, and the power lines access sites for the Carp River still had snow and were inaccessible to most vehicles. Pine River was accessible for shore fishing at the M-134 overpass bridge, but the DNR boat launch was inaccessible. There was still ice cover at the City of St. Ignace boat launches.

Les Cheneaux Islands/DeTour — There was minimal ice fishing activity in Hessel this past week with very little luck finding fish. However, the ice was no longer safe to be on in any of the Les Cheneaux Island areas. DeTour still had ice and saw no fishing activity.

Fishing tip

Water temperatures — Match your retrieve speed to the water temperature. In colder water, fish are less willing to chase, so a slower, more subtle retrieve often produces more strikes. As the water warms, you can gradually increase speed to trigger more aggressive bites.
