The name derives from Gautsjór from the male name Gautr, which may have become Gok.

Both draining rivers and inlets are located on the lake's northern shore. Storelv and Skorgeelva (Trollsåselva) are the two most important inlets. It is drained solely by Hagneselva, which flows into Åsrumvannet and eventually into Numedalslågen. Its most important inlet is the river Storelv, which flows from Askimvannet in Andebu.[3]

Fish species found here include Northern pike, European perch, Ide, Common dace, European eel, Salmon and Brown trout.[4]
