(Betsy Bloom/Daily News photo) A gull, probably a ring-billed, dozes in the sun Friday on the re-formed ice at Lake Antoine in Iron Mountain. The recent colder weather allowed the ice to reclaim many area lakes this past week, though only a thin layer that ebbed on the few days with temperatures in the 40s and 50s. It has slowed migration even as some new birds continue to make their way back. Next week should see a gradual warming trend, according to the National Weather Service.

A proposal in Michigan would expand the operation of Class 1 electric bicycles on state park-managed nonmotorized trails open to bicycles.

Class 1 e-bikes — e-bikes that are pedal-assisted and can go up to 20 miles per hour — are currently allowed only on improved surface trails. These are trails that are paved or consist of gravel or asphalt.

The proposed Department of Natural Resources land use change would expand allowable e-bike use to include Class 1 e-bikes on natural surface, nonmotorized trails on state park-managed land open to bicycles.

In addition, the change would allow operation of Class 2 e-bikes, which are throttle- and pedal-assisted and can travel up to 20 miles per hour, on both linear paved trails and state park-managed natural surface trails for mobility purposes as long as a cyclist had applied for and received a permit to do so.

A public survey is open through Sunday at https://www.research.net/r/DNR-E-BIKE.

Results will be shared during the April 11 Michigan Natural Resources Commission meeting and action may be taken at the commission’s May meeting. Statewide, about 3,000 miles of nonmotorized state park-managed trails open to bicycles would be affected.

“This change would make trails more accessible for people who may not have the physical ability to ride a traditional bike,” said Tim Novak, the DNR’s state trails coordinator.

The first noticeable push of walleye happened about a week ago on the lower Peshtigo and Menominee Rivers, the Wisconsin DNR said.

“Fish were seen from the walkway on Hattie Street (in Marinette) but were not very willing to bite,” the DNR said. “Best catches for walleye were reported by anglers vertical jigging the lower Menominee.”

The Michigan DNR reported this Upper Peninsula activity:

Little Bay de Noc: Weather created tough fishing conditions and limited pressure from anglers. Perch anglers that made it out were able to catch fish and reported good fishing when using perch rigs with worms or minnows. The Kipling, Rapid River, and Escanaba River docks are in, although there was shore ice reported at the Rapid River launch.

Marquette: Anglers fishing along the breakwall reported doing well when fishing for coho salmon. Due to weather, there were very few boats that were able to make it out on the water. Anglers who were floating down the Chocolay River did quite well catching steelhead and brown trout. Anglers fishing the Carp River reported consistently catching steelhead.

Au Train: Winter weather kept boats off Lake Superior. Anglers also reported slowed numbers of coho salmon being caught. Blue and silver spoons did well for coho.

Keweenaw Bay: Angling pressure was low due to inclement weather. Anglers who were able to brave the cold and rain were rewarded with splake, rainbow trout and brown trout caught mostly from shore. Anglers who had the most success fishing from shore were using spawn and casting near river mouths.
