Category One Upgrades

In 1985, the Department amended the Surface Water Quality Standards (SWQS) at N.J.A.C. 7:9B-1.15 to upgrade certain surface waters of the State to Category One based on parks, wildlife management areas, and trout production waters. Between 1985 and 2002, the Department designated more surface waters of the State as Category One. These upgrades were based on their value as trout production (FW2-TP) waters.

Since 2002, the Department has promulgated several amendments to the SWQS to upgrade the stream classification and antidegradation designations of additional waters of the State based on exceptional ecological significance or exceptional water supply significance. Links to proposed and adopted rule amendments from 2002 through the present are provided in the table below, along with maps of the stream classifications corresponding to each change to the stream classifications.
