The Biodiversity Monitoring Institute Reports on Alberta

The Alberta Biodiversity Monitoring Institute (ABMI) has released a series of reports that can be used to observe changes in land use and environmental variables.

See these web pages:

Human Footprint Map

Species

Some  of the map products will be useful for monitoring of the Sylvan Lake watershed, however the resolution is too low to monitor changes at the community or individual property scale.

News from the Alberta Recreational Lakes Forum 2017

Alberta Environment and Parks organized this year’s forum at Lake Isle west of Edmonton.

Several forum documents and presentations are filed in this online SLWSS folder.

The SLWSS did not attend this year’s forum as the need for input from community stewardship groups has declined. We did provide this report on our 2016 activities and projects:

SLWSS REPORT FOR THE ALBERTA RECREATIONAL LAKES (ARL) FORUM 2017

State of the Watershed 2016

Our comprehensive report “The Sylvan Lake Watershed-Second Edition” documented changes in the key indicators that affect the state of the watershed. Data on Environmental, Social and Economic Cumulative Effects variables were compiled for time periods of one or more decades and presented a picture of a relatively stable environment.

Water Quality Monitoring 2016

Preliminary analytical data indicate that in a year with little spring runoff the nitrogen and phosphorus nutrient concentrations have been lower than the long-term average. The lake water clarity remained very high with Secchi disk depth measurements typically greater than 5 metres. Photo albums of the lake sampling expeditions were posted on our SLWSS News blog site.

Nature Alberta’s Living by Water Program

The Society has promoted the Nature Alberta Living by Water program for several years and enabled more than 80 property owners to benefit from Home Assessments. Response to L by W has declined and we awarded a SLWSS yard sign to just a single property owner in 2016.

Government Affairs in 2016

The Society presented a statement on the potential impact of the West Area structure plan at a public hearing of the Town of Sylvan Lake with regard to transport of silt from construction sites through Marina Bay into Sylvan Lake in Golf Course Creek runoff. We recorded several cases of increased turbidity in stormwater runoff.

Groundwater Research

We assisted a University of Calgary geophysics survey team led by Profs. Lauer and Bentley to collect groundwater aquifer data at the west end of Sylvan Lake in October.

Quiet Enjoyment Initiative

The QEI subcommittee chaired by Kent Lyle continued its efforts to have local municipal bylaws adopted to control the sources of noise on the lake. An education and boat launch site signage project was developed at the request of the SLMC. Subsequent support by the municipal members of the SLMC was mixed and disappointing to the hard-working sub-committee. The QEI message resonated with and received considerable major and local media interest in its efforts to promote respect for others. An expanded QEI subcommittee report is posted here.

Community Outreach

Our ceramic tile for the new lighthouse is mounted on the structure with inscription: “Sylvan Lake Watershed Stewardship Society: Protecting the lake’s natural assets and values through vigilance and science”.

 

 

 

Juno Beach Comes to Sylvan Lake

The shoreline of Sylvan Lake is changing as McMansions replace those old time family summer cottages.

Architectural, environmental and aesthetic standards seem to be flexible. Living by Water principles that help property owners manage water balance and preserve the riparian zone with recommended low impact development and landscaping standards in some cases have apparently been eaten by the family dog.

One Birchcliff SV property owner has prepared for an invasion by sea as this section of re-contoured escarpment and shoreline now resembles Juno Beach in 1944:

Birchcliff vs Juno Beach

Shoreline impairment surveys document the degradation of the naturally protective riparian zone around the perimeter of the lake.

Spring Runoff in Golf Course Creek

The early snow melt runoff flowed quickly for a few days in late March. Here is the Golf Course Creek culvert that carries flow under Highway 11A into Marina Bay, then Sylvan Lake:

Flipside Kids Learn About Water Quality

This Sylvan Lake News story was published in the April 20 edition:

Children involved in the drop-in programs at the Flipside Youth Centre were taught some things about that big body of water at the north end of town, on April 13.

President Graeme Strathdee and Director-at-Large Susan Samson of the Sylvan Lake Watershed Stewardship Society gave an interactive presentation on the science surrounding the waters of Sylvan Lake.

Both representatives provided various examples of what affects water quality in the lake, as well aswhat procedures are used to test the quality of that water, such as pH testing.

“They talked to kids on how they do testing for farm runoff, and what comes out of rainwater thatends up in the lake,” said Deshon Lennard an FCC Youth Services Coordinator with the Town ofSylvan Lake.

Lennard said that in their presentation, Strathdee and Samson explained all the factors that affectthe lake, from tourist activity to bacteria from garbage. Their presentation also had a hands-onaspect, with children carrying out experiments that tested tap water quality.

“The kids got to do a scaled down version of the larger activities, with one simulating the types ofwater in the lake with cups,” said Lennard. “Each cup represented geographic areas in the lake, andthey used food colouring to differentiate the distinct areas of the lake.”

Lennard said that last Thursday’s session was part of a larger educational segment of the youthcentre’s programming called Power-up Thursday, whereby children engage in educational activities,that “engage them in diverse areas of science and math.”

“The kids were very interested and curious,” said Lennard. “They learned something new, and tooksome pride in learning about the water in the lake, because they’re from here.”

Our Stewardship Science message was built around this slideshow of water quality sampling of Sylvan Lake and Golf Course Creek.

Can you collect a composite sample of lake water like Breda is doing? Flipside kids can.

Thanks to Sam Macdonald, new SLN reporter just arrived from NS, for the reprinted story.

 

 

Sylvan Lake Shoreline Impairment Video Surveys

The Sylvan Lake shoreline has been surveyed twice using airborne video cameras to record the impairment of the riparian zone by property owners, once in 2002 for the Alberta Conservation Association and again in 2007 by Alberta SRD together with Fisheries and Oceans. These are valuable records of the cumulative effects of human impact on the natural values that otherwise would be provided by the shoreline environment to protect the lake.

This graphic summarizes the 2002 findings:

sylvan-lake-impaired-shoreline-2002-survey-v2

The shoreline sections occupied by the Town of Sylvan Lake and Summer Villages or equivalent county communities are typically Moderately or Highly impaired. The SLWSS has recruited property owners along those sections of shoreline to participate in the Living by Water program of Nature Alberta. Regrettably, less than 20% of shoreline occupants have volunteered to have property assessments completed.

These three helicopter survey files should playback on a computer or phone. If that doesn’t work, then download the files and play them locally:

The Atlas of Alberta Lakes is now online

The Atlas, first published as a printed report in 1990, has been digitized and is available here.

Sylvan Lake is part of the South Saskatchewan Region.

Maps and data for some lakes monitored by Alberta Environment and Parks may be found here.

and the AEP Lake Information page.
