Arlington and Roxbury Township are using this funding to implement two major storm basin rehabilitations.  Drainage upgrades are also planned in the Borough of Hopatcong and Jefferson Township. 

What are the Major Environmental Issues Facing the Lake?

The most important environmental issue facing Lake Hopatcong at this time is the flow of nonpoint source pollution into the lake.  Nonpoint source pollution in the form of stormwater runoff is the main source of excessive phosphorus and suspended solid loading to Lake Hopatcong, which can increase plant growth and decrease water quality.  Efforts to protect the lake's water quality is focused on reducing the nonpoint source pollution load to the lake.
