The week started out with summer-like weather and dropped in the first few days of October. This time of year I usually have the beach to myself.

Sunday, September 27th, 2020 – This sign is new since I last walked down this part of the beach west of 16th street – thoughtful of someone to warn people.
Monday, September 28th, 2020 – Lots of seagulls to the east of beach area 1
Monday, September 28th, 2020 – Taken from along the beach near 13th street. Where the beach is now was all grass two years ago. The high waters have eroded the shoreline significantly.
Tuesday, September 29th, 2020 – Walking back home from the provincial park at the east end of Wasaga Beach looking toward the main beach parking lot.
Thursday, October 1st, 2020 – Today I was in a race with the rain and just made it back in time. Taken near 15th street looking west.
Thursday, October 1st, 2020 – High waves have trapped water in this gully along what used to be beach drive.
Friday, October 2nd, 2020 – On Friday morning beach one has been groomed. Getting ready for the Thanksgiving weekend perhaps?
Friday, October 2nd, 2020 – A jumble of chairs at a property just west of 13th street. I’m not sure how they got there – strong south wind?

September rolls on and COVID numbers are sadly ticking up across the province. A pop-up car rally towards the end of this week didn’t make our mayor or town council very happy. Like all beach residents, I’m grateful to the town and the OPP for surging resources to Wasaga Beach to help keep things under control. I have no problem with people have fun and enjoying custom cars, but nobody has patience for idiots racing up and down residential streets.

News of the pop-up rally was widely reported in Ontario with local news coverage here – https://www.barrietoday.com/coronavirus-covid-19-local-news/pop-up-car-rally-unacceptable-says-wasaga-mayor-2737890. It’s only getting started as I write this on a Saturday, so I suspect there will be more news soon.

Sunday, September 20th, 2020 – September often has the best weather of the year and this week was gorgeous. With lots of off-shore wind the water level was lower than usual and the beach looked wider than it has. The water levels are still near record highs however. The first day we have a northwest wind, the beach will once again be underwater sadly.
Sunday, September 20th, 2020 – The beach was walkable today all the way from east of beach one to this damaged breakwater near 17th street (looking west). It became impassible again near 18th street and again in several places across beach 4.

Before I continue, just an interesting digression about great lakes water levels. The chart below comes from Fisheries and Oceans Canada.

https://www.waterlevels.gc.ca/C&A/bulletin-eng.html

The great lakes are all at different elevations. Lake Huron and Lake Michigan flow into one another such that they equalize at the same water level. Lake Superior is typically ~700 feet above sea level. Superior feeds Lake Michigan/Huron through a series of rapids and Lake Michigan/Huron is ~25 feet lower than Lake Superior. Water levels drop a further ~3 feet flowing through the Detroit River into Lake Erie. At Niagara Falls where Lake Erie drains into Lake Ontario, there is a further sudden ~326 foot drop and water continues to flow out at ever lower elevations through rapids along the St Lawrence River system to the Atlantic Ocean at sea level.

The chart above shows ~100 years or recorded history of Great Lakes water levels. The red bars are all-time high water marks, and the blue bars are all time lows. The Great Lakes were breaking records for all time lows as recently as 2012 to 2013. What the data shows is that through all of 2020, the Great Lakes have been at 100 year record highs. For example, in July 2020, water levels were above the previous record high last recorded in 1986. The dotted red lines project September 2020 and beyond are estimated highs, and the blue lines are estimated lows.  You can see that  present water levels are roughly 1.4 meters (4.6 feet) above historical long-term averages recorded over ~100 years. Needless to say, this is an enormous amount of water. The good news is that while water levels are projected to remain high, they appear to be dropping slightly below record levels. (see chart above)

Average water levels change seasonally (the gray fluctuating line that looks like a sine-wave). What makes things even more complicated is that the Earth’s Crust is not staying still. To account for this, a standard called the IGLD 85 (International Great Lakes Datum 1985) was published. This represents the sold horizontal black line. All water-level measurement are presently relative to IGLD 85. While this sounds crazy, IGLD 85 is an update from IGLD 55. (The datum needs to be re-calibrated every 25-35 years. this is because the earths crust is still slowly rebounding from the retreat of Glaciers that used to cover the great lakes region. A detailed explanation of IGLD 85 is here –  https://www.in.gov/dnr/water/files/11WhatIsIGLD1985.pdf. What makes this complicated is that the speed with which the crust is re-bounding is not uniform so the relative changes between the great lakes are not uniform. To put this in perspective, elevations at harbor beach in Lake Huron increased by slightly less than 1cm between 1955 and 1985. It’s been 35 years, so we’re due for a new IGLD standard reference.

Monday, September 21st, 2020 – More Piping Plovers along the shoreline with seagulls in the background. According to an article in Midland Today from the spring of 2020 there are only an estimated 150-250 birds across the great lakes, so it is great to see so many birds this year. https://www.midlandtoday.ca/local-news/tinys-newest-beach-users-dont-need-masks-or-even-a-permit-4-photos-2396074. Kind of shocking but there were only 8 breeding pairs in Wasaga Beach this year according to local news reports.
Wednesday, September 23rd, 2020 – Despite the waves, the wind continues to be slightly offshore keeping water levels low. It will be great to have a large beach again with the water levels get back near normal.
Wednesday, September 23rd, 2020 – Looking south from the beach across sand dunes just west of 13th street.
Thursday, September 24th, 2020 – Looking east across the beach at homes along Shore Lane to the west of 13th street.
Friday, September 25th, 2020 – Walk back along the river from the eastern end of Wasaga Beach. Main Street bridge in the distance spanning the river.
Friday, September 25th, 2020 – Looking east across what was formally Beach Drive. The roadway is now covered with sand due to record high water levels.
Friday, September 25th, 2020 – The main street bridge is under construction again now that the summer season is over. This year the focus is on the northbound lanes. You can see that they are doing a complete re-build of the bridge replacing all of the steel I-beams.
Saturday, September 26th, 2020 – Saturday was the pop-up car rally. Because of the high water, the cards could not get down to the beach. There were an estimate 1,000 attendees most concentrated around the area south of beach one.
Saturday, September 26th, 2020 – Lots of burning rubber on Mosely south of beach one today.
Saturday, September 26th, 2020 – Despite the car rally, the main beach was totally peaceful. Note the concrete barriers to the right. These were erected in the spring and backfilled with sand where the road used to be in order to protect business along the beach from high water.

Low 16.1 5.7 3.3 15.2 6.0 2.9

Despite the overnight lows still above freezing we had frost two mornings this week. I get my weather for this site from Weather Underground (an open-source site). My preferred weather station is IWASAG6 near beach area 4. https://www.wunderground.com/dashboard/pws/IWASAG6 

I took a lot of pictures Monday this week, because there were several interesting things to see. The Piping Plovers appear to be doing well this year.

I don’t know much about Piping Plovers but the pictures I took appear to be chicks. (see https://www.greatlakespipingplover.org/ ) – Piping Plovers are an endangered species around the great lakes, and local volunteers have gone to great efforts to protect their habitat including closing large sections of beach east of beach one during their nesting season.

Sunday, September 13th, 2020 – You know that Fall is coming when they start removing the garbage cans along the beach.
Sunday, September 13th, 2020 – Taken near 5th street – A few people on the boardwalk. This is usually one of the busiest areas in the summer. It’s amazing how quickly things quiet down.
Monday, September 14th, 2020 – Walking through the provincial park back to my truck at 18th street.
Monday, September 14th, 2020 – Piping Plover  chicks? I was practically tripping over them walking from beach 3 to beach 2.  They were flying over the water, but they move to quickly to get a picture – https://www.greatlakespipingplover.org/
Monday, September 14th, 2020 – Piping Plovers as far as the eye can see!
Monday, September 14th, 2020 – I’m reminded when I walk west from 18th street that Great Lakes water that levels are still at record highs. The damage across the full length of the beach is enormous.
Monday, September 14th, 2020 – Looking west from 18th street. I tend not to walk west anymore because parts of the beach are now impassible due to high water. (things gets better @ beach 5 and beyond)
Tuesday, September 15th, 2020 – Taken from the park @ 13th street looking east.
Thursday, September 17th, 2020 – Looking across Beach Drive – glad the cages are gone.
Thursday, September 17th, 2020 – What a change from a year ago. Where the sand is now was Beach Drive last summer.
Friday, September 18th, 2020 – Looking west towards Collingwood on my way from Beach one.
Saturday, September 19th, 2020 – Looking east across beach one along what used to be Beach drive.
