Is that a lake?
This photo illustrates the difficult history of Diamond Lake. It doesn’t look like a lake at all — and it might not have been. The 1938 annual report of the park board refers to “the dry lake bed at present.”
I recently received an email from a reader who lives near Diamond Lake who commented on the differences in how Diamond Lake is treated from other Minneapolis lakes in that there is no hiking or bicycle trail all the way around it. Many perceive the west shore to be private property. In fact, the entire lakeshore is park property. The photo above is undated, but I think it was shot in the 1940s. According to Hennepin County property records, the houses on the east side of Pearl Park were built in 1938.
At this time Todd Park — the dark area north of 57th Street at Portland — was referred to simply as the “east swamp.” It was dedicated as a “park” on the plat of the neighborhood, but it was, on average, 12 feet below the grades of surrounding streets.
Pearl Lake was filled in 1936-37, with dirt from extensive runway excavation and construction at Minneapolis Municipal Airport, which the park board owned and operated at the time. The runway construction and lake filling were both WPA projects. About 200 men and 75 trucks were assigned to the project in 1936. About one foot of peat was peeled off the old lake bed, a couple feet of airport fill smoothed over the skinned landscape, and the peat reinstalled as a top coat.
In the 1938 annual report of the park board, superintendent Christian Bossen wrote that Diamond Lake had almost dried up in the 1920s due to development and low rainfall, but, “With the separation of the storm water drainage from the sanitary sewers, the City Engineer is now using and expects to use to a greater extent Diamond Lake as a storm water reservoir.”
The 1938 annual report contains a detailed description of what the park board hoped to accomplish around Diamond Lake. It provides the details of an important chapter in the history of the lake and the neighborhood.
