Searching online for these place names only yields program notes from performances of Scheherazade, at least in English. And while this location is included in the [English Wikipedia article about the piece](https://en.wikipedia.org/wiki/Scheherazade_(Rimsky-Korsakov)#Background), it is absent from the [Russian-language version](https://ru.wikipedia.org/wiki/%D0%A8%D0%B5%D1%85%D0%B5%D1%80%D0%B0%D0%B7%D0%B0%D0%B4%D0%B0_(%D1%81%D1%8E%D0%B8%D1%82%D0%B0)). EDIT: I updated the English version of the page to include the site.
Obviously, place names can change, and this was in 1888. But do we know what lake or town these names refer to now?
tl;dr It's the name of a private estate outside of town of Luga in Leningrad Oblast.
