What Happened to all the Alewives in Lake Michigan?

Alewives are small fish native to saltwater but migrate to freshwater rivers and streams to spawn. They are also called River Herring, Sawbelly, Gaspereau, and Kyak. Alewives are a type of herring similar to Atlantic herring and are a good source of protein and omega-3s.

Alewives, a non-native species, entered the Great Lakes through canals, lacking natural predators, allowing their numbers to explode.

In the 1960s, the government began a program to restore the balance of the Great Lakes ecosystem. With the intentional introduction of predators to control the exploding alewife population, non-native salmon species like Coho and Chinook were introduced into the Great Lakes. These salmon preyed heavily on alewives, bringing their numbers down significantly.

Alewives primarily fed on zooplankton. A reduction of zooplankton populations in Lake Michigan due to invasive zebra and quagga mussels also contributed to their decline by limiting their food supply.

Eventually, the alewife population reached a more balanced level within the Lake Michigan ecosystem. While die-offs still can occur, they are far less frequent and much smaller than the massive beaching events of the 1950s through the 60s.

Alewives are sensitive to sudden temperature changes. Cold weather snaps following warmer periods could shock massive numbers of fish, leading to die-offs. 
Thousands of alewives cover a beach near downtown Chicago after being washed ashore by Easterly winds. Migrants from salt water, the fish pack Lake Michigan. After they spawn, they die. Chicago Park District crews have the messy, smelly job of clearing the beaches and freshening the air.


The sheer vastness of their population meant that these die-offs resulted in millions of dead fish washing ashore, creating a foul-smelling mess on Chicago's beaches.

Alewives are still present in the Great Lakes but in much lower numbers.

Shumway, Illinois, is One-Third of a Square Mile in Size.

The village of Shumway is an unincorporated community in Effingham County, in Southern Illinois, founded around 1856. The village population was 179 (2023). Shumway is part of the Effingham Micropolitan Statistical Area.

The quiet village of Shumway traces its roots back to the mid-19th century. While details of its earliest days are shrouded in the gentle passage of time, we know that the area was primarily settled by families seeking the fertile lands of the Illinois prairie. Farming became the lifeblood of the nascent community.

The village of Shumway owes its name to one R.H. Shumway, a visionary entrepreneur who played a pivotal role in shaping its identity. Originally established near what was known as Summit Station, the village would relocate to accommodate a depot on the Vandalia Railroad in 1881. This strategic repositioning fueled rapid growth. This growth is tied directly to R.H. Shumway, who founded his seed company in Rockford, Illinois.

In 1870,  Shumway established the R.H. Shumway Seedsman company, a modest enterprise that would transform the village and ultimately make an international impact. Shumway's innovative approach, commitment to quality seeds, and shrewd marketing acumen saw his operation quickly outgrow its initial premises in Rockford. Seeking a better location to accommodate his expanding business, Shumway's eye fell upon the small, farming-focused community that would eventually bear his name.

By 1881,  Shumway successfully relocated his seed company. The village, strategically located along a railroad line, provided excellent logistical advantages at a time when rail transport was vital. Shumway's seed business quickly blossomed into a commercial powerhouse. At its zenith, the company was renowned as the largest of its kind worldwide, dispatching upwards of 200,000 catalogs each year. 

As its economic fortunes soared, Shumway steadily built out the infrastructure and amenities, befitting a flourishing village. Businesses sprang up, catering to the needs of the burgeoning population. Homes multiplied, lining its streets and establishing a cozy residential character. Establishing institutions such as churches and schools cemented the village's sense of community and purpose.

This historic and picturesque church was established in 1864 and replaced with the current building shown in the above picture. It is a testament to the village's spiritual heritage. The date of 1864 refers to the congregation's founding.

The church you see today dates back to 1880, with additions, such as the parish hall, etc., made since then. The original structure was erected one mile north of town in 1865, but no records exist of whether any of that building or its materials were moved or they started rebuilding from scratch. The site of the original structure is still the site of Trinity's cemetery today, though it has been expanded several times over the years.

Shumway's success transformed the once-modest settlement into a thriving regional hub. R.H. Shumway Seedsman eventually became one of the largest seed distributors in the world by the time of Shumway's death in 1925.

The village of Shumway grew in tandem with the seed company's success. This small community on the vast Illinois plains became a surprising agricultural innovation and trade hub. Residents took pride in connecting to the Shumway name, which is recognized locally and in households nationwide. The Shumway seed catalog was a familiar and anticipated resource for countless farmers and gardeners, promising bountiful harvests year after year.

However, the world was changing, and even small communities like Shumway were not immune to those changes. The agricultural industry continued to modernize as the decades passed, with large-scale agribusiness increasingly displacing smaller operations. While the R.H. Shumway Seedsman company was eventually sold, changing hands and relocating, the village named for its founder perseveres.

Today, Shumway maintains its small-town charm. Visitors find a quiet and welcoming place with residents proud of their history as a center of seed distribution and rural life.
