Golf Course Creek Meets Sylvan Lake-2016-07-16

A few millimetres of rain in the last week:

Precipitation to 2016-07-16

Precipitation in 2016 measured at the Alberta Agriculture weather station at Hespero.

has increased the stormwater runoff from the Golf Course Creek catchment and transported another load of suspended solids into Sylvan Lake through Marina Bay:

See more evidence of lake contamination in this photo album.

The flow through the Hwy 11A and Marina Bay culverts creates a brown plume of nutrient rich fine particles when it disperses in Marina Bay before discharging into Sylvan Lake. Reports suggest that, as in previous cases that we investigated in 2015, even 20 mm of rain can saturate and fluidize soil at construction sites up the watershed slope in the Town of Sylvan Lake (TSL), carry it in stormwater into Golf Course Creek, through the Sylvan Lake Golf and Country Club property, and into Marina Bay.

With more land development scheduled in the TSL’s annexed West Area, Golf Course Creek should expect to receive similar contamination in the future unless the best low impact development practices are applied as the SLWSS has recommended and contractors are required to comply with the Water Act and other Alberta environmental regulations.

 

 

Sylvan Lake Water Quality Tested Again

July 12 was the second day of the Sylvan Lake Watershed Stewardship Society-led 2016 campaign to sample and analyze the water quality of Sylvan Lake as part of the Society’s long-term project to monitor the condition of the lake and its tributaries. Alberta Lake Management Society’s field technician Breda Muldoon, a U of S toxicologist by training, follows the official lake monitoring protocol so that data meet the standards of the Alberta Environment lakes database. Charter captain Ed Thiessen of Norglenwold, and SLWSS directors Steven Johnson of Birchcliff S.V. and Graeme Strathdee of Sylvan Lake provided on-board assistance.

See this photo album for more lake sampling action.

The water, plankton and invasive species samples that are collected are analyzed by Edmonton-area labs and results are eventually disclosed to the public by ALMS in a Lakewatch-series report, like this one for 2014.

Extra samples are taken this year to compare the nutrient composition near the surface and bottom of the lake at its deepest point. Phosphorous (the element P), an important nutrient for green phytoplankton, accumulates in the lake sediment and is released to the hypolimnion, an oxygen-depleted layer. As an in-lake diffuse source of P it is important for us to understand the potential for fertilization of chronic algal blooms when that layer is mixed through the water column by seasonal temperature cycles and water density changes.

The 2016 water quality monitoring project is funded by Alberta and feeral government agencies that support the work of ALMS, the Red Deer River Watershed Alliance, and the SLWSS. The Sylvan Lake Management Committee has accepted our invitation to participate in the project as a learning experience. The inter-municipal group will contribute $500 to the project and provide two on-board observers for the August sampling dates.

 

 

 

Do-It-Yourself GIS for Your Watershed

Learn how to build a Geographic Information System for your Alberta watershed by using this starter kit from the Sylvan Lake Watershed Stewardship Society.

The process involves downloading free software, acquiring georeferenced data for your land and lake area, and creating maps that will help you to understand and make better decisions about your watershed.

The linked slideshow and notes explain the GIS software options, where to find and download GIS data and imagery, and some of the useful mapping functions that will help you to survey your environment, answer questions, and to add value to your GIS project.

Geographic Information System for the Sylvan Lake Watershed

The brand new SLWSS Geographic Information System (GIS) demonstrated at CARL  2016 received rave reviews from participants.

Two mapping technologies, QGIS and Google Earth Pro, have been applied to compile and display watershed information for stewardship applications. Here are a few examples:

Where is the boundary of the watershed.? It must be there somewhere.

This image shows several different perimeters, one based on an Alberta Hydraulic Unit map that only encloses part of the watershed; A wiggly white one that makes no sense; and a practical red one that accurately follows the high land.

A Google Earth Pro survey tool allow precise identification of changes in the slope of the basin using satellite-based ground elevation data. Regional tributaries shown above in purple flow into and away from Sylvan Lake depending on the topography.

This next colorful map shows a few of the many layers of GIS data acquired from Alberta and national data banks:GIS Data Dump-001

Ground topography; Lake bathymetry; Soil types; Roads; Tributaries; The watershed boundary; Fishery survey stations; Railroads

TSL Divide-001

In the image above, GIS survey tools are overlaid on this Town of Sylvan Lake imagery to locate the 50th Street ridge that determines if stormwater flows east and out of the watershed to the Red Deer River, or west towards Golf Course Creek.

Green map pins at the peak of the ridge also define the area of the town that is inside or outside of the watershed boundary. Stormwater paths determine the direction of flow of any spilled contaminants or urban pollution. Sylvan Lake is exposed to that  west side flow.

Railway Berm Wetlands-001

High resolution Google Earth Pro satellite imagery (one computer pixel can represent one square foot on the ground) and layers of GIS data, enable rapid investigation of land areas that are important for water quality protection.

The land between the railroad berms west of 60th Street is part of the recently annexed West Area five quarter sections that extend from Highway 11 to the lake shore.

Caution will be required to preserve the wetland services of that gully which is also the flow path of the important Golf Course Creek tributary.

 

 

 

Watershed Stewardship at CARL 2016

The 2016 Central Alberta Recreational Lakes forum, held at the Best Western Chateau Inn on Saturday May 14, attracted 46 lake participants from as far north as Lac Isle and many staff from government departments and agencies. Watch this blog for links to the presentations after the organizer, Janine Higgins of Alberta Environment and Parks, posts them on the CARL website.

The event was organized and sponsored by Alberta Environment and Parks (AEP), the Sylvan Lake Watershed Stewardship Society (SLWSS) and the Sylvan Lake Management Committee (SLMC).

SLWSS VP Susan Samson Leads the Urgent Care Campaign

Click here to read the feature article on the Urgent Care project in the Sylvan Lake News edition of April 21.

While our Watershed Stewardship Society priorities are a healthy environment and Sylvan Lake’s water quality, watershed residents and visitors must be healthy too, and have quick access to emergency services 24/7.

Please visit the Urgent Care website to learn more about the campaign and how you can help. VP Susan and the campaign team will welcome your support.

The Red Deer General Hospital is just a 24.7 km ambulance ride away from the Town of Sylvan Lake

Remember that the Red Deer General Hospital emergency department is only an ambulance ride away when Sylvan Lake clinics are closed and your life might depend on you receiving the prompt medical attention that your taxes pay for.

Where does this year’s $20.261 billion of health care spending go if it’s not meeting our community’s Urgent Care needs? That’s more than $4800 per person for each of the 4.23 million people in Alberta. And it’s almost $100 million of annual spending on our regional population of 20,000 people.
