Then and now

When was the wooden dam for Oswego Lake replaced by a concrete dam that allowed the levels of the lake to be controlled?

Stay tuned to the end of the newsletter to find out more!

Wooden dam

The wooden dam (pictured here) presented unique problems during weather events. Several times, the dam was severely damaged during a flood. There were many dams throughout Oswego's history, placed along different locations, although this one was the major dam connecting the lake to the creek. 

From the desk of the Executive Director

We're open on Saturdays now! This has been a big dream for a while now. I can't tell you the number of times I've heard something along the phrase of, "We'd love to come visit, but we aren't able to because of your hours!" Now, we'll be open on Saturdays from 11:00 AM - 2:00 PM, which means more families, working people, and youths will be able to visit and discover Lake Oswego history.

This is only possible because of our museum docent program. Eleven people signed up to our training and have prepared to come in Saturdays throughout the summer. After summer, we'll be able to take a look at how many people came through Saturdays and adapt our new program from there. THANK YOU to those who have volunteered! 

If you've been looking for an excuse to visit the Heritage House, here it is! Drop by on a Saturday, meet our new docents, and learn something new. We'll be having some special events upcoming that are worth visiting for.

From the archives

FROM THE VOSE COLLECTION... 

Parent letters to Irma Vose

If you think classrooms today are much different than classrooms in 1939, check out this handwritten note offered to Miss Vose, a teacher at the Oswego Public School, from a concerned parent. 

Dated December 20, 1939, the first letter is addressed to Miss Vose, a teacher. The writer identified at the end as Mrs. Gertrude E. Stevens, expresses concern about “the trouble” involving students—specifically mentioning twins and a boy named Clifford. Mrs. Stevens refers to “some foul language supposed to be used by one of the twins” and makes clear that such behavior is not tolerated at home: “We never allow any nasty talk in our conversation or allow the children to use it.”

Mrs. Stevens goes on to suggest separating the twins from Clifford, whom she describes as someone who “does nothing but fight and pick quarrels.” Whether this is entirely fair or parental bias is hard to say, but it's certainly a conversation still familiar to teachers today!

First Wednesday Chautauqua for May 2026

OIN US ON WEDNESDAY, MAY 6TH, AT 5:30 PM FOR OUR LAST PRESENTATION OF THE SEASON

When we look at historic houses, the first thing we see is often the spacious front porch. It seems that every house built between 1890 and 1930 had a porch! This was an era when front porches were expected on houses, and when those porches were used. What was our culture like in those “good old days”? And... What did people do on their porches? This was an era when front porches were expected on houses, and when those porches were used. What was our culture like in those “good old days”?

Kay Demlow, dressmaker, fashion historian, and creator of The 1909 School, will share stories from porches long ago, and will spark ideas for spending time on your porch.

1921!

The building of the 1921 concrete dam

While people like Albert Durham, JC Trullinger, and Socrates Tryon operated dams in the 19th century, the first wooden dam built by an iron company was in 1860, with a higher dam completed in 1866. This, combined with the new canal in 1872, increased the length of the lake. 

In 1921, the first concrete dam, built by the Puget Sound Dredging Company, allowed for the levels of Oswego Lake to be controlled.
