Dear Shareholders and Easement Members,
We are looking forward to another great year on the lake in 2023. As promised in my previous message, the purpose of this email is to update you on our plans for the upcoming year. Areas of focus include budget, water quality, safety, events, etc. Please take the time to read it through. If any questions or comments arise, please reach out. We really want to hear from…
LOC Communication regarding 2023 Assessment and Special Assessment
Following its annual review of Lake Oswego Corporation’s budget and expenses, the Board of Directors has approved a 3.5% increase in the annual assessment to help offset rising costs due to inflation, as well as a special assessment to…
With the end of the year approaching, I wanted to make sure and send out a quick update ahead of our closure for the holidays. It looks like we might get a small blast of wintry weather later this week. While they are not calling for much snow or ice (if any). you should be aware that boat lift canopies don’t need much additional weight on them to start having problems. If you are going to be out of town, it’s a good idea to have someone check for you should we get any…
As you can see from the recent water quality update we realized a temporary benefit from the alum application the end of July that improved water clarity. We don’t have all the data from that time period (particularly nutrients and phytoplankton), but we do know the application stripped algae and cyanobacteria cells from the water column, taking them and the phosphorus contained inside to the lake bed. This led to…
Our new website is up and the water quality information you see will be a bit different than before. There will be weekly sampling summaries posted on the Lake Data page that provides graphical trends of water quality data. Certain data we collect are available the same day, but nutrients, phytoplankton, and zooplankton data need to be analyzed by an outside laboratory, which can take a few weeks. Charts will…
This has been a frustrating and disappointing year for water quality. My last posting on August 12 was somewhat positive about the potential for a good summer, hoping the alum treatment later in the month would stave off a serious cyanobacteria bloom. However, that is not how things turned out, with cyanobacteria still active in mid-October.
Historically our phytoplankton starts with a large population of diatoms in…
Summer came on in a hurry this year and the lake is getting a bit green as a result. We usually end up with a green lake this time of year but we were optimistic the wet spring would lead to good conditions all summer. However, when you have a week of 90-100 degree weather it erases any gains from the late spring. The weather is going to get warm again next week so no relief is in sight.
Even though the average…
We had some interesting weather at the office on Monday (May 2), but not everyone in the watershed experienced the event. At the LOC weather station on our office building roof we received a combination of hail and rain amounting to almost 2.5 inches of precipitation for the day. A bit to our south near Hallinan they received over three inches from the storm. However, it was another story two miles away at the Lake Grove swim park weather station, where less than 3/4…
We have had a dry and relatively warm February so far, with a high temperature of 67 degrees at the marina on the 13th. This will not last if the predictions for March and April are correct. Since we are still in a La Niña weather pattern, March and April are predicted to be cooler and stormier than average, but May is predicted to be warm. This will be good news for snowpack and lake health as it will…
Swimming season has arrived. As the weather warms, we are finding more people swimming, floating and playing in the open water (lake areas outside designated swim parks/areas). Whether you are a recreational swimmer going for a quick dip to cool down, or a competitive swimmer taking part in a training session, take these common-sense precautions to stay safe…
