The radar technology developed to find water on Mars is cheaper and more effective in detecting leaks in public water systems compared to traditional ones. And now it has arrived in Michigan.

The Lake Michigan and Lake Huron waters governed by an 1836 treaty are at the heart of negotiations between Michigan, the federal government and Native American tribes to determine how much and what kinds of fish can be harvested by recreational, state-licensed and Native American commercial fishers. Much has changed since the treaty was signed, notably because of invasive mussels. But change created by human activity was underway even before the signatories to the Washington Treaty ink dried in Washington D.C. in March 1836.

Since the early 2000s fewer young whitefish have been making it to adulthood. Understanding the decline of lake whitefish recruitment is important for fishery managers and regulators as they approach the deadline to update a 2000 consent decree that regulates recreational and commercial fishing in Lake Huron and Lake Michigan.

How the shape of the Great Lakes now compares with their past is important as negotiators update the consent decree addressing commercial and recreational fishing interests in waters covered by an 1836 treaty. The deadline is at the end of June, the third such decree covering these contentious waters. The most recent one in 2000 was for 20 years, and it’s overdue for an update.

The impact that quagga mussels have on the Great Lakes food web gives deep meaning to the saying, ‘food for thought.’ These prodigious filter-feeders are implicated in the decline of many Great Lakes fish species, well beyond those with commercial and recreational value.

The food web in lakes Michigan and Huron has changed in ways that jeopardize age-old fishing traditions and raise questions about how we’ve managed them. Now negotiators are updating a legal settlement that spells out where and how much lake whitefish and lake trout can be harvested.
