The North Central Region Water Network is a recently formed partnership between extension agencies and professionals in twelve states. The network was created to help foster collaboration between researchers and extension staff throughout these states addressing water issues common to the region.
The Current, a webinar series designed to connect people with the new network and the water issues that are critical to the region, held the first round of presentations earlier this month. IISG’s water resource economist Margaret Schneeman was among the presenters for the inaugural webinar, Managing Water Supply: Resources for Education, Engagement, and Research, and she highlighted the work done so far to address water supply planning in northeastern Illinois. Gary Zoubek of the University of Nebraska-Lincoln Extension, and David Lusch from Michigan State University presented for the webinar as well.
Through both the webinars and collaboration between extension programs, the North Central Region Water Network hopes to expand water protection efforts, research, and the spread of information throughout the states. Visit the webpage (linked above) to learn more.

Asian carp may be getting a foothold in waters near Lake Erie according to recent water sample analysis.
“Multiple water samples taken from the Muskingum River last fall carried the environmental signature of bighead carp, an invasive species threatening the ecosystem of the Great Lakes. A report released Friday by the Nature Conservancy — in conjunction with the Muskingum Watershed Conservancy District, the Ohio Department of Natural Resources, and researchers from Central Michigan University — indicated 10 of the 222 samples from the river tested positive for bighead carp eDNA.
Asian carp have been established in the Ohio River for more than a decade, but these eDNA results indicate the fish could be present in the Muskingum some 80 miles north of where the Muskingum joins the Ohio at Marietta.
The Muskingum has a series of old dams and deteriorating locks, but if the genetic evidence is accurate, those have not provided a significant impediment to the carp moving up the river system.”

We first introduced you to Alice Denny last year when she worked as an IISG summer intern. Well, we liked her too much to let her go. When her internship ended, Alice became the newest member of our aquatic invasive species (AIS) team, located at the Chicago Botanic Gardens.
As an outreach assistant, Alice works on wide range of projects, including finding new opportunities to connect with recreational water users, aquarium hobbyists, water gardeners, and more. She will spend much of the summer spreading the word about AIS at professional and amateur fishing tournaments. Her message to anglers and boaters will be simple—be sure to remove, drain, and dry after a day on the water.
Prior to her internship with us, Alice worked as a field technician in the Chicago area and conducted research on invasive species in New York state parks. She holds a Bachelor’s in Biology from Hartwick College and is a member of the Illinois Volunteer Lake Monitoring Program.

With the big spring thaw underway (mostly) and warmer weather on the way, Lakes Michigan and Huron are on track to get closer to their long-term water levels than they were last summer.
“Water levels on Lake Michigan- Huron typically rise from March through July. Lake Michigan- Huron has risen one inch since early March, but is 13 inches higher than this same time last year. Although the above two lakes are higher, they are still 16 inches below the long term average for this date.
The rise in the lakes in the past month was the result of melting snow. Precipitation didn’t help much to the rise in lake levels, as March was fairly dry. The dry pattern in March was good for helping Michigan avoid major flooding. However, heavy rain would have really boosted lake water levels. March precipitation over the Lake Michigan-Huron drainage basin was only 1.49 inches, which was 69 percent of normal.”

Lake Erie is one of the Great Lakes that is most affected by toxic algal blooms, and finding the cause for them is the first step in reducing or preventing them. Scientists may be closer to understanding just what causes these harmful blooms.
“Algal blooms and dead zones in Lake Erie were severe during the 1960s, caused primarily by large releases of phosphorus from sewage and industrial plants. The 1972 federal Clean Water Act and the 1978 bi-national Great Lakes Water Quality Agreement led to dramatic reductions in phosphorus from these sources and a rapid improvement in water quality.
Lake Erie, however, saw a reemergence of the algal blooms and the growth of the dead zone in the mid-1990s, and the problems are worsening. In 2011, for example, Lake Erie experienced its most severe bloom of toxic algae on record. Last fall a toxic algal bloom in the lake forced officials to shut off a public water supply system in Ohio.
The new studies, part of the Ecological Forecasting (EcoFore) Lake Erie project led by researchers at the University of Michigan, found that the current targets to reduce phosphorus to alleviate algal blooms in Lake Erie may not be low enough to revive the dead zone. That conclusion informed the International Joint Commission’s recommendations in February for improving Lake Erie’s water quality.
The findings, and those of other studies from across the Great Lakes region, are delivering an ever clearer picture of the specific causes of nonpoint phosphorus runoff, algal blooms, and dead zones. The basic drivers of these problems are no longer unknown. The new research fills a critical void in information that has been often cited as a reason that strict regulations on nonpoint pollution sources, including agriculture, were not regulated under the 1972 federal Clean Water Act.”

Members of the House of Representatives from Great Lakes states are lobbying their colleagues in Congress to continue funding the Great Lakes Restoration Initiative.
“Forty-six House members from both parties recently sent a letter to leaders of a subcommittee that recommends spending on the environment.
It requests $300 million for the Great Lakes Restoration Initiative. The program usually gets about that much for projects dealing with threats such as toxic pollution and invasive species. President Barack Obama’s 2015 budget would cut it to $275 million.
Rep. Sander Levin of Michigan says the program has done much to improve the lakes’ health and now isn’t the time to cut back.”

The IISG aquatic invasive species team (AIS) kicked off their fishing tournament season with a bang earlier this week. Several members were onsite April 6 for a high school bass fishing tournament to talk with young anglers about the threat of AIS and what they can do to prevent their spread. Hosted by the Illini Bass Fishing Club, the third annual High School Open drew a record number of teams and anglers to central Illinois’ Clinton Lake.
IISG science writer Anjanette Riley joined the AIS team for the tournament and recalls the day’s events:
“If every fishing tournament this year was like the High School Open, this will be a great year for AIS outreach. During the couple hours we were onsite, Sarah Zack and Alice Denny talked with hundreds of anglers, coachers, and on-lookers from Illinois and Wisconsin.
But more than the numbers, what really made Sunday a success was people’s enthusiasm. Groups huddled around the IISG table to talk about Sea Grant, invasive species, and three easy steps to ensure invaders can’t hitch a ride to new waterbodies: remove, drain, dry. Many of these coaches said they would take the message—and the Stop Aquatic Hitchhikers giveaways—back to team members not competing that day. And frequent announcements from Luke Stoner, the Illini club president, reminded the crowd of the risks AIS pose to their sport and the importance of “leaving the lakes better than we found them.”
The day also proved successful for many of the anglers fighting to catch the most and biggest bass. The fish were hesitant to bite, but more than half of the 79 competing teams weighed in at least one. Several teams brought in bags of fish weighing more than 6 lbs. The winning duo, though, sealed their victory with two fish weighing in at 8.3lbs, and the Big Bass award went to an Edinburg-South Fork student who caught a 6.46lb largemouth bass—a true “Clinton Lake slaunch.”
These hard-working high school anglers have a full season of fishing in front of them. In fact, for many of the teams, Sunday was their first day on the water this year. And their successes at the tournament will help them qualify to compete in sectional and state competitions.
Sunday was the first of many tournaments for IISG’s AIS outreach team as well. Sarah, Alice, and others will take their message of prevention to professional and amateur tournaments across Illinois and Indiana this spring. But the annual High School Open marked a rare and important opportunity to talk with young anglers about the importance of curbing the spread of AIS.”

White Lake, located in Michigan just north of Muskegon, has long been listed as an Area of Concern in the Great Lakes region. Federal officials are currently moving forward on one of the last efforts to remove the lake from the AOC list.
“The lake is one of 14 major sites in Michigan on a list of toxic hot spots in the Great Lakes region. The cleanup work is difficult and expensive, but it’s expected to improve conditions for people and wildlife throughout the region.

While the spring thaw will be a welcome change of weather in most of the country, there is a risk that snow melt and spring rains could lead to rivers exceeding flood levels.
“The continuation of winter weather, above-average snowpack, frozen ground and thick ice coverage on streams and rivers will delay spring flooding into April in the upper Midwest eastward to New England.
The intensity of the flooding will depend on the rate of snow and ice melt, and future rainfall.
Continued well-below average temperatures this winter resulted in significant river ice formation and ice jams in locations further south than customary, flooding homes and businesses, and impacting river commerce.
There is also an elevated risk of more ice jams this spring in the northern tier of the U.S. from Montana eastward to northern New England.
‘This year’s spring flood potential is widespread and includes rivers in highly populated areas putting millions of Americans at risk,’ said Louis Uccellini, director, NOAA’s National Weather Service.
‘Although widespread major river flooding is not expected, an abrupt warming or heavy rainfall event could lead to isolated major flooding.'”
