By: Cliff Aichinger, Administrator, Ramsey-Washington Metro Watershed District

I proudly accepted this award at the Minnesota Association of Watershed Districts Annual Conference on December 6th. The award was presented by John Jaschke, Executive Director for the Minnesota Board of Water and Soil Resources.


I want to first acknowledge that the other excellent staff at the District and our innovative and visionary Board of Managers play a huge part in making me look good. I want to thank all of them for shaping our success. I consider this award to be recognition of the District’s successful watershed management activities and projects. I have been privileged to work in a supportive work environment where innovation, creativity and leadership is encouraged and fostered. Without this approach from the District Board we would not have had the courage to push the envelope on innovative projects and programs like WaterFest, the Lake Phalen Shoreline Restoration, the Tanners Lake Alum Treatment Facility, the Maplewood Mall Volume Reduction Retrofit Project, the District Volume Reduction Rules, our BMP cost-share incentive program, Living Streets and many others.

Too Much of a Good Thing in Lake Owasso?

As we all prepared for our Thanksgiving celebrations, something very disturbing was taking place on Lake Owasso. Nearby residents ventured onto the lake to take a break from the holiday hustle, and many were shocked to see dead fish scattered just under the newly formed ice. Immediately after the discovery, residents made phone calls and shot off emails that alerted state and local agencies. News crews were on the scene to cover the story.  Since the onset of the reports, managers and research scientists have been working to determine what caused the fish kill. Below is an update.



The fish kill was initially investigated the Saturday after Thanksgiving (November 30th) by DNR biologists. A large number of dead game fish, primarily panfish, were observed in Owasso. Newspapers articles showed dead largemouth bass, walleye, and muskie just under the ice. Fish were found mainly in the shallows, scattered around the lake.

Is it possible that a chemical was responsible for the kill? Well, there were no outward signs or reports of a chemical spill around the lake. Aquatic plant control was last conducted in August, and the herbicide would be at very low or undetectable levels going into fall.



Fisheries biologists doubt that a fish disease was the culprit. However, samples of dead fish were brought to DNR’s pathology lab for analyses. Results should be available in a couple of weeks.

Until these other things are officially ruled out, the most plausible explanation for the kill has to do with too much of a good thing- oxygen.


Fish need ample but balanced oxygen in the water to survive, so it was one of the first things scientists tested for. Dissolved oxygen testing on Saturday revealed high levels in and around the shallows where dead fish were identified. Additional oxygen testing was performed by the Ramsey County Public Works Environmental Services staff on Monday, December 2nd. Again, test results pointed to normal to high dissolved oxygen levels.  

Although uncommon in lake systems, water can actually accumulate too much gas, like oxygen, under certain conditions. This phenomenon is called “super-saturation.”

The super-saturation fish kill hypothesis that is currently being talked about has to do with photosynthesis and ice formation. The thesis goes like this: There were unusually high levels of algae (phytoplankton) in Owasso going into fall. As an early-season ice sheet formed on the lake, we experienced sunny periods without any snow cover. With these conditions, the algae likely had a high rate of oxygen production (through photosynthesis), and this oxygen could not diffuse into the air because of the newly formed ice sheet. With a lot of algae, a clear ice sheet, and sunny conditions, it is possible to have super-saturated oxygen levels in lake systems.

With the excess oxygen levels in the water, fish experience symptoms like the “bends” that scuba divers suffer when they ascend too quickly. Gas bubbles form in the blood stream, causing a blockage in blood flow, which can eventually lead to death. This condition, however, is quite difficult to detect in nature, due to the gas bubbles dissipating quickly after a fish dies (usually less than 24 hours). Because of this, it is too late to run tests on the Owasso fish and gain meaningful results.


Although uncommon, fish kills have been reported on other lakes in the Midwest immediately after ice formation. For instance, a similar occurrence happened on Forest Lake last year. Dead fish were tested for disease, but nothing turned up.

TJ DeBates, DNR’s East Metro Fisheries Supervisor, will be evaluating the extent of the fish kill in the spring. He states that DNR may adjust the stocking rates of walleye and muskie to compensate for any substantial game fish loss that was experienced from the unusual fish kill.


This kill has reminded all of us that our urban lakes are complex systems. Although we can’t say with certainty that too much algae caused the fish kill, we can state that it is a condition that we just don’t want to see. Watershed, lake management, and individual homeowner activities are critical in working to bring phosphorus levels down, which will in turn, reduce algal blooms.

If recent fish tissue or water quality testing reveals any novel findings, we will let you know.

Neighborhoods Turn into Living Classrooms

By Tracy Leavenworth and Sage Passi


Conrad Freeks, longtime Beaver Lake resident shares his stories and perspective with
L'Etoile du Nord fourth graders.

This fall two fourth-grade classes from L’Etoile du Nord French Immersion and a second grade class from Battle Creek Elementary left behind their traditional classrooms to engage in interactive watershed learning experiences in their East Side neighborhoods. Ames Lake, Battle Creek and Beaver Lake became the “living classrooms” for Nick Gasho’s and Audrey Gagnaire’s fourth-graders and Don Booth’s second-graders who explored the surroundings of their nearby water resources by bus and on foot.


These neighborhood tours were designed by Watershed District staff to introduce students and teachers to water-related issues that are happening right “in their back yards” and connect them with local watershed stewards who can provide ideas, inspiration, and assistance for meaningful service projects that students can implement in their own community. This fall, the community partners who supported these initial investigations included Maplewood Nature Center and St. Paul Community Education’s Service Learning Program.

L’Etoile du Nord’s Investigation at Ames Lake reveals some “hot buttons”

Sage Passi uses quilt pictures to explain the
history of Ames Lake to French Immersion students.

  Preparation for these field trips involves an introduction to watershed basics and some hands on learning in the traditional four-walled classroom. Before venturing to Ames Lake, Gasho’s fourth-grade class used squares from a story quilt to learn the history of how the lake was once filled, paved over and covered with a shopping mall back in the early 1960’s.
Ames Lake, though much different now than it once was, is a success story of urban habitat restoration in the City of St. Paul that still faces some on-going challenges.


On their field trip at Ames Lake the fourth-graders “met” the native plants that surround the lake and learned that efforts to manage the area were needed to remove invasive plants. They learned that the prairie around the wetland needs to be burned periodically to remove unwanted species and to nourish the soil. They explored the variety of habitats the plants provide for animals and birds and documented issues including invasive species, turbid water, litter and graffiti. 
 

French Immersion students enjoy a first-hand experience of Ames Lake’s ecology on their scavenger hunt.

“My students loved the activities and are excited to keep it going,” said L’Etoile du Nord French Immersion teacher Gasho in a follow-up email after his tour in late October. During their enviro-scavenger hunt bingo at Ames Lake, Gasho commented that the students, who would normally have had a difficult time focusing in the classroom, worked enthusiastically to recognize native plants and documented landmarks and issues they discovered around the lake.  


This coming winter and spring his students will have the opportunity to meet some of the local enthusiasts and elders who have been involved in the neighborhood projects. They’ll return for a visit in the winter and then when the lake thaws in the spring, they’ll investigate the water quality, study animal and insect life, learn how the area connects to other wildlife corridors and bring their learning to life through a service learning project.



Uh-oh....graffiti!

Kathy Sidles, a local environmental activist, joined French Immersion fourth-graders at their clean-up event at Ames Lake last spring. It’s a partnership that she hopes to continue with French Immersion students this year and augment their efforts by uniting multiple East Side St. Paul schools in a joint effort to clean-up and remove invasive plants at Ames Lake and along the Bruce Vento Trail that runs through St. Paul neighborhoods.

 

Battle Creek gets a visit from Don Booth's motivated second-graders



Beginning the adventure along
the creek corridor.

Battle Creek, the stream in East St. Paul that precipitated the birth of Ramsey Washington Metro Watershed District in 1975, has spawned many watershed heroes through the years, including a long list of teachers, students and citizens who have taken on the mission of advocating for and protecting its water quality and nearby habitats by building rain gardens, installing trench drains and doing creek shoreline restoration and buckthorn removal.

Battle Creek Elementary second-grade teacher, Don Booth, no stranger to teaching, is a recent transplant to the neighborhood and is destined, in all estimations, to become a hero in the area in the near future. It may be his first year teaching at Battle Creek Elementary, but he has an impressive track record of guiding his students to watershed action and community involvement in many projects over the years. While teaching at Parkway Elementary School on the east side of St. Paul a number of years ago, he and his fourth grade students installed a native garden and took on the goal of saving the large wooded area and open space next to the school to prevent it from being sold by the School District. His efforts helped set the stage for the next school that moved into the building. Following the lead of Don and other Parkway teachers, L’Etoile du Nord moved forward in Parkway's former space to complete a butterfly garden, a large scale hillside restoration project and a rain garden on the school grounds.

middle school classes and residents.

This fall’s field trip in the Battle Creek neighborhood provided an opportunity for Don and his class to find their bearings in the neighborhood. They took a walking tour to the creek near the school and observed how water carrying pollutants flows to storm drains and then into Battle Creek. They visited two rain gardens and met a couple of the neighbors who built them with the help of Battle Creek Middle School classes a few years ago. They learned how rain gardens prevent run-off from polluting the nearby creek and took note of the problem of buckthorn as they walked along the creek corridor.


As the year progresses, it will be inspiring to see how these second graders turn their observations into action steps with the guidance and seasoned experience of their teacher, Don Booth.

Audrey Gagnaire’s fourth-graders team up with Beaver Lake residents and Maplewood Nature Center

Ann Hutchinson shares her LEAP Award-winning garden with
French Immersion fourth-graders.

Gagnaire’s tour began at the home of Maplewood Nature Center Naturalist, Ann Hutchinson, who lives across the street from the west shore of Beaver Lake. Ann is a longtime partner of the Watershed District who provides education for the community about watershed issues and helps lead citizens to take action. A few years ago she helped the Nature Center become a model for “Protecting Water One Rain Drop at a Time,” by installing innovative best management practices (BMPs) and colorful signs to communicate clean water messages to the community.

Nature Center that help to maintain clean water.

Ann initiated French Immersion’s trip by doing some teaching on her own turf – her home turf that is. Turf is not exactly a word in Ann’s vocabulary. Ann’s mission is to “replace” turf in her yard by planting beautiful native plants that perform water-cleaning functions and provide great habitat for birds, butterflies and other creatures. She and her husband, Rich Lindell are the recipients of a LEAP (Landscape Ecology Award Program Award) in 2007 for their sustainable yard practices. 

Students discover a place above Beaver Lake where runoff is causing
erosion on the hillside leading down to the lakeshore.

 
After identifying examples of watershed stewardship in her yard, Ann guided the students along the sidewalk above the shores of Beaver Lake, pointing out erosion issues and calling attention to wildlife and plants present in the area. The next tour stop, a couple blocks from her home was at Achieve Learning Academy to explore two rain gardens that the school established in 2011 with help from the Watershed District. While there, Gagnaire’s fourth-graders collected seeds from the native plants in the rain gardens and learned how their long roots soak up water and protect it from being polluted before it ends up in nearby Beaver Lake.

For their next stop, the French Immersion fourth-graders visited eighty-eight year old resident and self- taught Watershed Steward, Conrad Freerks and his wife, Yvonne on the east side of the lake. Freerks recently attended one of RWMWD’s Community Conversations in the Watershed and sent the District a long letter documenting his observations from around the lake including a tally of people who frequent the paths around the lake. Students listened to his stories about how the area surrounding the lake has changed over time while walking down to the shoreline below his Beaver Lake home.


The neighborhood tour culminated at Maplewood Nature Center where students explored the watershed features on the site that included several rain gardens, pervious pavers, a cistern, a drain channel and a rain chain. They interacted with teaching tools inside and outside that related to ecosystems and water quality protection. Delighted students were surprised with hot chocolate from the Nature Center and chocolate cookies freshly baked by Conrad’s wife, Yvonne. It was a welcome treat on such a cold day!

As this class considered the issues they encountered on their neighborhood tour (erosion along the lakeshore, a build-up of leaves in the lake near the outlet and lake level fluctuations pointed out by Conrad), they also took note of the partnerships developing between the Watershed District, homeowners and the Maplewood Nature Center. They will have much support on their chosen project in the spring!


Our partners who help us with our investigations and projects such as these are invaluable. They are the ones helping students determine how clean their water is and what their role can be in improving it. Our partners are critical conduits who help us find and make connections between people and places. They show us the way to tap into resources, inspire a group’s imagination, foster visions, share knowledge of the community and teach leadership skills.

Rain Garden Pilot Program Recap: Year 1

By Nicole Soderholm, District Inspector

As we’re sure you’ve all noticed, it is definitely winter. The District’s rain gardens have temporarily turned to ‘snow gardens,’ but not before Minnesota Native Landscapes was able to finish the year’s maintenance on the rain gardens selected for RWMWD’s pilot study targeting rain gardens in Little Canada. If you’ve missed the introduction or mid-summer update of our pilot study on rain garden maintenance, take a quick peek at our April 11, 2013 and June 6, 2013 Ripple Effect posts for more information.

RWMWD has enjoyed contracting with Minnesota Native Landscapes this year, and we’re all impressed with the noticeable changes to the function, health, and aesthetics of the rain gardens under their care. Regular maintenance is truly one of the most important factors in improving the function and longevity of a rain garden –preserving its ability to effectively capture and filter pollutants in rainwater.

This year, maintenance included weed and debris removal (trash, leaf litter, etc.), sediment removal, mulch replacement, and cutting back plants to allow for new growth. In October, Minnesota Native Landscapes planted a variety of native plants in over 30 rain gardens in Little Canada that had previously been looking a little bare. See some species examples in the photos below. We’re excited to see these new plants flourish this coming spring!

Left to right: Swamp milkweed (Asclepias incarnate), tussock sedge (Carex stricta), Jacob's ladder (Polemonium reptans), wild bergamot (Monarda fistulosa).

Now that we’ve gotten these rain gardens back to their height of function and beauty, we are planning on implementing ‘Year 2’ of this pilot study. We are especially interested in whether we will see a change in the amount of time and materials spent now that the gardens have been regularly maintained for an entire growing season. Stay tuned for future updates!
