In 1712, Cistercian cartographer Mauritius Vogt confused the Bradlava with the Úhlava in his book, and also made a typographical error when he wrote it as Úslava.

[1] The Úslava originates in the territory of Kolinec in the Blatná Uplands at an elevation of 637 m (2,090 ft), on the slope of the Zálužnice mountain, and flows to Plzeň, where it enters the Berounka River at an elevation of 299 m (981 ft).

[2] The longest tributaries of the Úslava are:[3] The river flows through the municipal territories of Kolinec, Číhaň, Zavlekov, Hnačov, Plánice, Újezd u Plánice, Mlýnské Struhadlo, Neurazy, Žinkovy, Prádlo, Klášter, Vrčeň, Srby, Ždírec, Blovice, Zdemyslice, Žákava, Nezvěstice, Šťáhlavy, Starý Plzenec and Plzeň.

[2] Many fishponds were founded directly the Úslava; the largest of them are Hnačovský, Žinkovský and Labuť.

For most of the year, the Úslava is not suitable for river tourism due to lack of water.
