- We will haul and install cedars at several locations in the river.
What You Should Bring
- Chest waders (in water work) or be prepared to wet wade
- Long sleeve shirt
- Sunblock
- Heavy work gloves
- Water
What the DNR & TCTU Will Provide

Registration will close 24 hours before the event for an accurate list of participants.
Irrigation Water Testing – Hampton (city)
Dakota County, the Dakota County Soil and Water Conservation District and the Minnesota Agricultural Water Resource Center will be offering farmers who irrigate their crops the opportunity to test their irrigation water for nitrogen. Testing is at no cost.
Participants will receive their results the same day. They will learn how to credit nitrate in their irrigation water for next year’s nutrient management plans. Participants will also walk through the Irrigation Management Assistant (IMA) Tool with a SWCD staff member. The tool helps with irrigation scheduling.
Private well owners can also have their drinking water tested for nitrate. They will receive their results and treatment recommendations, if applicable.
Sampling instructions for irrigators
Samples may be taken the day of analysis or ahead of time. Samples taken ahead of time must be frozen until attending a session to prevent samples from degrading.
Participants may bring in several frozen samples collected over a period of several days to get a more representative result.
Samples can be collected directly from irrigators or by installing a boiler drain to a pivot point or the well itself.
If sampling directly from irrigators:
- Allow irrigators to pump water for at least 15 minutes before sampling.
- Fill a clean 5-gallon bucket, or similar container. Mix before collecting the sample.
- Collect the test sample in a small Ziploc bag or a clean bottle or container. Only about 1 ounce of water is needed for testing.
Sampling instructions for private well owners
- Collect samples from your primary drinking water source after eight hours of nonuse, preferably first thing in the morning
- Collect your sample in a small Ziplock bag or clean bottle or container
- Do not run the water before sampling — collect the first draw in the container
- Only about 1 ounce of water is needed for testing, but collecting extra is advised.
Test results
Nitrogen results are confidential. Participants are not required to take any action after testing. They will receive their results and information on nitrogen crediting.

Meet-a-Stream Day with Minnesota Trout Unlimited
Join MNTU education specialist and long time fly angler, Evan Griggs, at his favorite MNTU habitat project sites. Tour the project site to see how habitat work benefits the stream. Learn about stream ecology by sampling macroinvertebrates to determine water quality and see what the trout are eating. Then we’ll practice our fly fishing skills, like casting and knot tying, before heading out to try and catch some trout.
Our programs are tailored for kids, families, and newer anglers. This is a great way to explore some new fishing spots, understand how our habitat projects benefit trout, and grow your fishing skills! All gear provided and no fishing license or trout stamp are required for participants at these events. For ages 10+, an adult must accompany their minor(s) at all times. If looking to register more than 3 people or have questions, contact Evan Griggs, tic.mntu@gmail.com.

Native Seed Collection at Vermillion River Linear Park – with Friends of the Mississippi River
Gathering the seeds of native plants in order to be able to restore other areas to more natural habitats is important work. It’s also a very enjoyable and educational activity. Come and learn more about the native plants in our area parks.
After a brief introduction and training, volunteers will collect native prairie seeds on the restored sandy-soil prairie. The FMR land conservation team will redistribute the seed to areas of nearby Vermillion Falls Park that have lower plant diversity. This seeding will help improve habitat for pollinators and grassland birds.
All are welcome, however capacity is limited, and registration is required. All supplies and training will be provided, and volunteers will work closely with FMR staff. This event is part of the Vermillion Stewards program, engaging Vermillion River Watershed residents to learn about the local watershed while working to protect and enhance its unique natural resources.
Space is limited, so sign up today!
Imagine a Day Without Water
Come take a tour of Lakeville’s Water Treatment Facility to see where the city’s groundwater becomes potable water. Learn how your home’s water usage affects our drinking water supplies and the quality of lakes and rivers.
Lakeville Water Treatment Facility
8400 Ipava Ave., Lakeville
Friday, Oct. 18
Tour times: 8:30 a.m., 10:30 a.m. or 1 p.m. Register now.
Redd survey on South Branch Vermillion River
What’s A Redd?
Trout are gravel nest spawners. Females excavate a nest, called a redd, where they deposit eggs. These eggs are fertilized by one or more male trout and then covered by gravel. Counting the number and distribution of redds over time provides data on the health of our streams. TCTU has decided to begin collecting redd data on the trout streams in our service area, data that we can share with the DNR, other agencies and anyone that is interested.
What Will We Be Doing?
- Doing TCTU’s 1st ever redd survey
- We will be walking the stream (about 1.8 miles) searching for and documenting redds
- We hope to have a total of 9 volunteers
The Plan
- Meet at the start time at the parking lot of the AMA.
- We will break out into teams, and walk sections of the river searching for and documenting redds.
What You Should Bring
- Clothes appropriate for the weather!
- Chest waders as some of you will have to cross the stream!

Volunteer for Winter Salt Week – Jan. 27-31
Join Dakota County and local watershed organizations in sampling for chloride in water. Stop by a Dakota County Library branch to pick up sampling materials and learn how you can use less salt and reduce chloride pollution while staying safe this winter.
Chloride levels in Minnesota’s lakes, rivers and groundwater are increasing over time, largely attributed to overuse of de-icing salt. One teaspoon of salt pollutes five gallons of water, with no feasible way to remove it. Salt damages property and the environment, harms aquatic species and impacts drinking water quality.
With friends or family, collect a water sample from a local lake, stream, or wetland and test it for chloride using the Izaak Walton League of America’s Salt Watch Kit. Choose any Dakota County library and sign up to collect testing supplies at that location Jan. 27 – 31.
Your testing kit will include a list and map of streams, ponds or wetlands near the libraries where you can collect a water sample from. Report the data/share the results to the Clean Water Hub. All materials needed and instructions will be provided by the county.
Participating library branches include:
- Burnhaven Library (Burnsville)
- Farmington Library (Farmington)
- Galaxie Library (Apple Valley)
- Heritage Library (Lakeville)
- Inver Glen Library (Inver Grove Heights)
- Kaposia Library (South St. Paul)
- Pleasant Hill Library (Hastings)
- Robert Trail Library (Rosemount)
- Wentworth Library (West St. Paul)
- Wescott Library (Eagan)
While at your favorite Dakota County library:
- Browse book displays on winter topics. Pick up a bookmark with the book lists.
- Have fun on a scavenger hunt.
- Learn how to be a Smart Salter and pick up a cup to use the right amount of salt if it is needed.
- Know what watershed you live in and how you can help protect local water resources.
- Kids activities include Salty Dawg activity book, temporary tattoos, origami and buttons!
- Learn from Salty Dawg and take the pledge to be a Smart Salter. Find more information about the pledge at all library branches and on the Dakota County website
More information about Winter Salt Week
Winter Salt Week is January 27-31, 2025. This event is a collaboration of governmental and non-governmental organizations across the United States and Canada. Winter salt use damages infrastructure and threatens the health of lakes, streams and drinking water. The goal of the event is to engage with Minnesotans on chloride pollution in your community and continue ‘working to keep freshwater fresh.’
Visit www.wintersaltweek.org for more information and to learn about the daily webinars including Minnesota speakers providing public works perspectives and presenting on the policy solutions panel.

Winter safety tips:
- Wait until roads are safe to travel before driving to a sample location.
- Wear crampons or shoes with good traction.
- Approach water where the ground is flat and not slippery.
- NEVER walk on the ice over the water.
- Sample where ice is thin enough to easily break through and reachable from a stable spot on the bank.
- When in doubt, come back when conditions improve.
General safety tips:
- Wear fluorescent clothing when sampling during hunting season or along a roadway.
- Dress appropriately for weather conditions.
- Be sure to sample on public property or secure landowner permission first.
- Park carefully when sampling near a roadway.
- Go with a partner or make sure someone knows where you are going and when you are expected to return.
