State

Pond dyes

DEP

A pond dye used to control algae or plants (for example by blocking light) needs the joint Chapter 91 permit like any other chemical. A dye used only for color does not, and in a pond fed only by runoff or groundwater it may be applied according to the label. But if a stream flows into the pond and water flows out, dyes and other products that change the water's appearance generally may not be used unless DEP authorizes it.

Also check with your municipality

Your township, borough or city (and county)

Ask about zoning, building and floodplain permits. Your county, township or municipal government may have its own rules, codes or permits for pond construction or maintenance, so check with every level of local government before you start, especially for a new pond.

Owner

Ask the lake's owner first

The utility or company that owns the lake

The owner's shoreline permit is required in addition to state permits. Ask the owner for its shoreline rules and approval before you apply; its approval doesn't replace state permits, and state permits don't replace its approval.
