4+ loops
lake nokomis open swim
64 degrees (air) / 70-72 (water)
clouds then rain then sun then clouds
Hooray for Friday morning open swim! Overcast and calm water. For the first 100 yards, the water felt slow and cold, then faster and invigorating. At the last reading (tues, july 2) the water temp was 72, but it rained a lot, so I’m thinking the temp maybe went down a degree or two? I should start tracking the temp to see how much it fluctuates.
Because the buoys are positioned by lifeguards every swim — they paddle out on kayaks where they are advised by someone on shore where to drop their anchor — and because there’s no exact spot for each of buoys, the loop distance varies. Today it was long, which I like — the more distance, the better! Here’s a comparison on 3 different 4 loop swims by number of strokes I took / distance (which I’m pretty sure my watch doesn’t measures accurately):
25 june 2024: 2094 strokes / 3100 yards
30 june 2024: 2124 strokes / 3600 yards
5 july 2024: 2374 strokes / 4000 yards
I should note that my stroke count is very consistent. It’s kinda amazing to me how steady and even and similar my stroke count per 100 yards is across the summer.
For much of the swim, I felt strong and focused: 1 2 3 4 5 breathe left 1 2 3 breathe right 1 2 sight 3 4 5 breathe left. Not much thinking, some noticing:
10 Things
- the particles in the water — just ahead of me, reminding me of confetti or glitter, not so much moving through them as moving with them
- at first the water felt cold, invigorating
- for 3 loops: a white cloud-covered sky
- a car in the parking lot had its headlights on — glaring bright yellow
- visibility: very good for lake nokomis — if I had tried, I think I would have read my watch underwater!
- watching my hands underwater: stretching slicing, ghostly pale
- another swimmer’s legs coming into view, glowing white under the water
- loop 4 sun, 1: patches of soft blue sky
- loop 4 sun, 2: shafts of light underwater, illuminating the particles and making them sparkle
- as I neared the beach, surveying the way the bottom went from deep to shallow — a steep drop-off!
In the middle of the swim, I decided to recite Anne Sexton’s “The Nude Swim.” I had memorized part of it a few years ago, but this morning I memorized all of it. Such a great poem — I really like Anne Sexton’s voice. I should read more of her poems.
still my favorite lines from it:
All the fish in us
had escaped for a minute.
The real fish did not mind.
We did not disturb their personal life.
aquatic plant management
A few days ago, I looked up information about the vegetation/vines that I swim above in lake nokomis. I looked them up a few years ago, and recall learning that they were milfoil, but this summer I started doubting that I was remembering the name right. I was! There are two types of watermilfoil:
Eurasian watermilfoil : invasive, choking out native plants
Northern watermilfoil: native, food for the fish
On the Minneapolis Parks’ site, they describe aquatic plant management, which was fascinating. The most effective way to control Eurasian watermilfoil is to harvest it, either with a mechanical harvester or by scuba divers (!). The mechanical harvester, which from what my bad eyes can see is a boat with a big spinning blade
removes plants that are in the top four to six feet of water. The harvested plant material is removed from the water and stored until the end of summer when it is brought to the Minnesota Landscape Arboretum to be used as organic fill for their operations.
Aquatic Plant Management
The scuba divers, who only do this on Wirth Lake and Lake Nokomis, hand-pull the watermilfoil in areas that are inaccessible for the mechanical harvester. I wonder what areas are inaccessible and if I’ve ever witnessed the scuba pulling and not realized it. Very cool!
The water was at least 10 degrees colder than the Y pool (82 degrees), but not that cold. Still, by the end of loop 3 (almost an hour in), my hands were getting a little numb. When I got home, I took a long, hot shower. I’d love to be able to swim in very cold water someday — one fantasy: moving to the UK and swimming in the ocean all year round. The other day, I watched this video and thought, I want to be able to do this with other woman, laughing and freezing and loving it:
