Here's a dusty Koenig Lane looking east towards that fancy new reservoir in 1937. N. Lamar now crosses Old Koenig just past the reservoir.

The reservoir still exists today on Old Koenig Lane. The above photo was taken from about where Old Koenig Lane splits off from the new Koenig Lane which now passes the reseroir to the right in the old photo.
