Lake Mendota Freeze

A Christmas cold snap and low wind helped Lake Mendota officially freeze on Wednesday, December 27. Lake Mendota is the largest lake in the Yahara Watershed. The lake froze 17 days after the smallest lake in the watershed, Lake Wingra, which officially froze on December 10.

The Wisconsin State Climatology Office requires ice to hold for a period of 24 hours before a lake can officially be declared frozen over. After ice took shape on December 26, staff waited to see whether it would hold out through the night. The December 27 freeze date is five days ahead of last winter’s January 1 freeze date, and only seven days later than the December 20 median freeze date. The latest freeze date for Lake Mendota was January 30 – which happened in the winter of 1932.

Dear Friends,

Another year has come and gone on our lakes. Thank you for being a Friend of Clean Lakes. Today, I have only ONE thing on my holiday wish list – healthy lakes.

DONATE today to support our work.

As 2017 closes, we’re already pulling together phosphorus-reduction and water quality numbers for our State of the Lakes annual report. In the meantime, I’m looking back on a few things that have made ME happy this year.

Seven things that make James & the lakes happy:

Leaf Management

Help spread the world about leaf clean up and phosphorus reduction this fall. Removing leaves from the street can greatly reduce the amount of nutrient loading this season.

Joe Parisi press conference

MADISON, Wis. — On Monday, Dane County Executive Joe Parisi announced an aggressive 2018 budget, with numerous projects aimed at diverting and removing algae-causing phosphorus from lakes in the Yahara Watershed. The multi-million dollar proposed budget calls for continuing to remove legacy sediment from streams feeding into Madison’s lakes, as well as new projects like prairie restorations and a pilot “algae pump” to remove scum from surface water.

“Our mission looks to build a community of people, businesses, organizations, and government agencies dedicated to improving and protecting water quality in the Yahara River watershed,” said Clean Lakes Alliance Executive Director James Tye. “The county executive’s lake projects are a strong step in the right direction towards cleaner and healthier lakes.”

Water Quality Monitoring

2017 monitoring season

What started in 2013 as a handful of Clean Lakes Alliance board members testing the water has now grown into a network of over 70 volunteers doing weekly water quality monitoring on all five lakes.

Each week this summer, our team of monitors gathered data on water clarity and temperature. They also made visual observations on beach conditions and identified potentially harmful cyanobacteria (blue-green algae) blooms. And what a summer it was!

Foley and Lardner Volunteer Day

With 58 miles of lakeshore in our watershed, shoreline maintenance is a big job. We’re lucky to have dedicated staff and community groups working to keep our parks and beaches healthy – but sometimes, there just aren’t enough hands to get the job done. That’s where our summer volunteer groups come in!

A summer to remember

So far this season, there have been 15 Renew the Blue volunteer days, for a total of 457 volunteers and 1,481 hours maintaining our lakeshores over the season. These events serve double duty: our lakeshore parks get some much-needed TLC, and volunteers learn more about keeping our watershed healthy.

Farm field and tractor

Here in Wisconsin, manure is on the mind as we work to improve local water quality. A recent Isthmus interview with retiring University of Wisconsin-Madison Center for Limnology director Steve Carpenter reminded all of us of the scale of the phosphorus problem facing our lakes. We often are asked what Clean Lakes Alliance is doing to tackle these issues locally.

Dane County is made up of a large urban population and thriving agricultural community. We greatly value the need to partner with farmers on solutions that will really work.

Clean Lakes Alliance, in partnership with Yahara Pride Farms and Endres Berryridge Farms, hosted our fourth annual Farm Tour on Tuesday, August 22nd, 2017. The event was held at the Endres Berryridge Farms manure compost site in Waunakee, Wisconsin.

The event brought together more than 120 attendees (farmers and suburbanites alike) to learn about manure composting as a manure management technique. Roughly 50 guests were members of the North American Manure Expo traveling from as far as Ontario, Canada to participate.
