This would be where I would tell you the fascinating history of why the winter harbor at Rogers City was referred to as the Frog Pond, but I’m unable to find much except for that’s what everyone calls it. There’s one in Toledo too.

The Presque Isle County Historical Museum is located in the historic home of Carl D. Bradley, general manager of Michigan Limestone and subsidiary Calcite Transportation. About the photo, they write:

Ice is Nice: Tracking Ice Cover on the Great Lakes

Ice on Michigan’s Great Lakes has become something of a phenomenon in the last few years, attracting photographers and thousands more to see the ephemeral beauty created by wind, water, and freezing temperatures. But ice has other important purposes, as NOAA’s Great Lakes Environmental Research Laboratory page on Great Lakes Ice Cover explains:

Ice formation on the Great Lakes is a clear signal of winter. Looking back in time, the lakes were formed over several thousands of years as mile-thick layers of glacial ice advanced and retreated, scouring and sculpting the basin. The shape and drainage patterns of the basin were in a constant state of flux resulting from the ebb and flow of glacial meltwater coupled with the rebound of the underlying land as the massive ice sheets retreated.

Heavy ice cover can reduce the amount of evaporation from the Great Lakes in the winter, thus contributing to higher water levels.

In bays and other nearshore areas, ice forms a stable platform for winter recreational activity such as ice fishing. This stable ice also protects wetlands and the shoreline from erosion.

  • 94.7% ice coverage in 1979 is the maximum on record (data began in 1973)
  • 9.5% ice coverage in 2002 is the lowest on record
  • 11.5% ice coverage in 1998, a strong El Niño year
  • The extreme ice cover in 2014 (92.5%) and 2015 (88.8%) were the first consecutive high ice cover years since the late 1970s.

NOAA pegs the current ice cover at 9.9% and you can also watch an animation of the last 60 days of ice formation. You can check out satellite images of the Great Lakes for current ice cover and also this cool animation of Great Lakes ice cover from 1973 – 2016.

Mark took this photo a little over a week ago at Lincoln Township Park near Stevensville. With the warmer weather, there’s probably less. View his photo bigger and see more in his Michigan Winter slideshow.

Know Your Michigan Fish: Northern Pike (Esox lucius)

The Michigan DNR’s Northern Pike page has this to say about this apex predator of the Great Lakes and Michigan’s inland lakes:

As predators, northern pike can have significant impact on their prey species. As with muskies, pike lurk in the cover of vegetation in the lake’s clear, shallow, warm waters near shore, although they retreat somewhat deeper in midsummer. Pike consume large numbers of smaller fish – about 90 percent of their diet – but seem willing to supplement their diet with any living creature their huge jaws can surround, including frogs, crayfish, waterfowl, rodents, and other small mammals. Their preferred food size is approximately one third to one half the size of the pike itself.

Great Lakes pike spawn in the shallows in April or May, right after the ice leaves, and before muskies reproduce. As a result of their eating habits, young pike grow rapidly in both length and weight. Females become sexually mature at age three or four years, and males at two to three years. Beyond sexual maturity, pike continue to gain weight, although more slowly. Great Lakes pike have an average life span of 10 to 12 years.

Pike eggs and new hatchlings (which stay inactive, attached to vegetation for their first few days of life) fall prey in large numbers to larger pike, perch, minnows, waterfowl, water mammals, and even some insects. Larger pike have two primary enemies – lampreys, and man. Spawning adult northern pike, exposing themselves recklessly in the shallows, are vulnerable to bears, dogs, and other large carnivores.

Northern pike flesh excels in flavor, thus making them a doubly rewarding game fish. Since their skin has heavy pigmentation and an unappetizing mucous coating, most people skin them or scale them carefully.

This photo was one of Isle Royale National Park’s “Wildlife Wonders of the Week.” They noted that a five pound female pike will lay about 60,000 eggs. Two weeks later fertilized eggs hatch, hungry for microscopic morsels. Once to the fingerling stage, food scarcity may force them to eat their own siblings for nourishment.

Line 5 and the Great Lakes

“There is a pipeline that‘s sitting at the bottom of the Straits of Mackinac. It was designed for a 50 year life and it’s been down there for 63 years. There’s a risk involved in this.”
-Mark Shriberg, National Wildlife Federation

In Line 5 puts Great Lakes at risk on Absolute Michigan via the University of Michigan (video below):

Up to 152 miles (245 km) of coastline in lakes Huron and Michigan could be fouled by a single oil spill at the straits, according to the simulations. When all 840 simulated spills are plotted on a map, a total of 720 miles (1,162 km) of shoreline in the U.S. and Canada are considered potentially vulnerable to spills that would require cleanup. Seven hundred twenty miles is roughly the distance from Detroit to Atlanta.

Areas at highest risk include Mackinac and Bois Blanc islands, as well as locations directly east and west of Mackinaw City. Communities also at risk include Beaver Island, Cross Village, Harbor Springs, Cheboygan and other places along the lakes Huron-Michigan shoreline.

…”Until now, no one knew exactly how much shoreline was vulnerable to spills in the Straits of Mackinac,” said Schwab, a research scientist at the U-M Water Center. “These findings show that under the right conditions, a spill in the Straits of Mackinac could affect a significant amount of shoreline and open-water areas in either Lake Michigan or Lake Huron, or both, very quickly.”

Failure of Poe Lock at the Soo Locks would be devastating

via today’s Five Things you need to know about Michigan on Absolute Michigan comes a Detroit Free Press report on  the potentially dire consequences for the US & Michigan if the Soo Locks fail:

A U.S. Department of Homeland Security report indicates a 6-month shutdown of the Poe Lock in Sault Ste. Marie, if one occurred, would plunge the nation into recession, closing factories and mines, halting auto and appliance production in the U.S. for most of a year and result in the loss of some 11 million jobs across the nation.

The report, obtained by the Free Press through the Freedom of Information Act, paints a grim picture of the outcome of any long-term shutdown of the Poe, the only one of the so-called Soo Locks able to handle the 1,000-foot-long vessels that each year move millions of tons of iron ore from mines in Minnesota and northern Michigan to steel mills dotting the lower Great Lakes and beyond.

….But what is also clear from the Homeland Security report is that while a longer-term shutdown would be catastrophic, even a shorter one could have a much wider impact than previously thought: If such a closure occurred at the Poe during the March 25-Jan. 15 shipping season, for instance, as much as 75% of the nation’s steel output could be halted within two to six weeks.

Doing nothing about Asian carp probably isn’t going to work

Traverse City based AP Environmental Writer John Flesher is (for my money) one of the best reporting on Great Lakes issues. His latest piece Effort to keep Asian carp from Great Lakes appears stymied begins:

When scientists discovered six years ago that aggressive Asian carp had made their way up the Mississippi River’s tributaries toward the Chicago area, the Obama administration and alarmed state officials pledged swift action to head off an invasion they feared could devastate fishing and boating on the vital Great Lakes.

Since then, federal agencies have spent more than $300 million on stopgap measures, including placing electric barriers on one likely route, a shipping canal that leads to Lake Michigan. But as the carp get closer_some are within 80 miles of the lake— the quest for a surefire deterrent seems to be coming up empty.

An advisory panel that has debated solutions for several years is scheduled to hold what may be its final meeting Thursday, with no sign of a consensus plan, several members said in interviews.

Even if talks continue, chances are growing that the carp will arrive before anything conclusive is done to stop them. At their recent pace, the first young carp could reach Lake Michigan within two years, although a number of obstacles could slow them considerably.

“It’s one of the things that keep me up at night,” said U.S. Sen. Debbie Stabenow, a Michigan Democrat whose state borders four of the five Great Lakes. “Asian carp could devastate our Great Lakes and the hundreds of thousands of jobs that depend on them.”

…Environmental groups and the region’s fishing and boating industries, which generate $23 billion annually on the lakes, are most worried about two varieties of Asian carp: bighead and silver, which weigh dozens of pounds and gorge on the same tiny plant and animal life that feeds the lakes’ other fish. Scientists are still measuring their impact in rivers, but under worst-case scenarios, the large carp could leave popular sport fish to go hungry and suffer population drop-offs. Asian carp are edible but bony, and most Great Lakes fish connoisseurs regard them as a poor substitute for the walleye and whitefish.

Additionally, silver carp are notorious for springing from the water when startled, sometimes ramming boaters with bone-cracking force — a hazard that some fear could damage the Great Lakes’ tourism industry.

Read on for much more, and be sure to follow John on Twitter for more of the story. And please, make it clear to every elected official you interact with how important the health of the Great Lakes is to Michigan!
