Our focus is to improve the understanding and appreciation of North American Bears, their role in the ecosystem, and their relationship to humans through education, research and rehabilitation.

NJDEP Division of Fish & Wildlife - Bear Facts for New Jersey
Black bears are the largest land mammal in the Garden State and live in forested areas throughout northern New Jersey. Here in the most densely populated state in the nation black bears are thriving in close proximity to people.

 (Moss Animals those blob things)

Preservation of rare species - The lake provides an ideal environment for bryozoa - fresh water jellyfish.  In the world, there are only 50 of these species that inhabit freshwater.  We are one of a few lakes located east of the Mississippi that where this species thrives.  The species we have in Lake Swannanoa is Pectinatella magnifica.  This variety is an indicator of water purity.  It thrives in our lake and cleanses the water.

They're the ones who are leaving all the empty mussel shells under your rowboat, because beavers are strictly vegetarian.

Lake-Friendly Fertilizer

Your yard maintenance has a direct impact on the water quality of our lake. Excess nutrients lead to algae blooms and weed growth. If you feel you must use lawn fertilizer, you may not use fertilizer containing any phosphorous. This applies to all of Jefferson Township, NOT only to Lake Hopatcong. Please be aware that any runoff into the lake has an effect.

Jefferson Township Code Book, Chapter 240: FERTILIZERS, APPLICATION OF
240-3. Regulations for fertilizer application.
A. Fertilizer. Within the Township of Jefferson, no person, firm, corporation or franchise shall apply liquid or granular fertilizer which contains phosphorous.
B. Time of application. Lawn fertilizer application shall not be applied when the ground is frozen.
C. Disposal of leaves and other vegetative material. No person shall deposit leaves or other vegetative materials on roads or within any lake or stormwater drainage system.
D. Buffer zone. Fertilizer applications shall not be made within 10 feet of any wetland or body of water.

Japanese barberry (Berberis thunbergii)

Leafs out early, shading natives woodland plants, overtakes thier habitat. You'll know it's what you've just pulled up by the acid yellow roots.

Invader of the Month-April (Connecticut Invasive Plant Working Group)

Japanese Knotweed (Fallopia japonica or Polygonum cuspidatum)

Exceptionally invasive, crowds out native species. Get rid of it by repeatedly cutting plant down, being sure to kill all pieces of vegetation by drying it out or burning, since fragments can sprout new plants, and/or treating cut stems with glyphosate (see below). Or you could try eating it (spring shoots are edible). Heavy infestations can be seen along Berkshire Valley Road. Also seen at a few lakeside locations at Lake Swannanoa. Identified in winter by dead light-brown bamboo-like stalks, blooms late summer in white fleece-like clusters.

"For control of emergent or floating aquatic plants or plants growing along a shoreline (where spray will contact the water), the RODEO formulation of glyphosate should be used. RODEO does not contain surfactants included in ROUNDUP products. Prior to applying any pesticide to a body of water or to plants in a wetland, one must obtain a permit from DEP. The half-life of glyphosate in water is approximately 2 weeks, but it does not significantly affect submerged plants. Glyphosate toxicity to fish and other aquatic organisms is very low." From: Connecticut Invasive Plant Working Group Website: SAFETY AND ENVIRONMENTAL CONSIDERATIONS FOR THE USE OF HERBICIDES TO CONTROL INVASIVE PLANTS

Just getting started, mid-Spring. Spreading lakeside infestation of Japanese Knotweed.

Japanese Knotweed Alliance: The Plant & The Problem

"Spread the word, not the weed" Pamphlet

Japanese Knotweed - Reynoutria japonica, information page

"Japanese knotweed is listed as a wild edible plant, and young shoots up to 30cm (1 ft), can be cut early in the spring, steamed or boiled and served like asparagus. Slightly older stems can be used to make a rhubarb-like jam by peeling and boiling the sour rind with sugar and pectin. FBCP do not advise or recommend that Knotweed is eaten."

Purple Loosestrife

invasive purple loosestrive in bloomBlooms during July and August. It grows on the lakefront and also thrives in standing water. If you see this plant, pull it up (roots and all)! Cut off blooms and dispose of in sealed trash bag before composting. See entire northern edge of North Lake for how much this plant can take over. See links below for more information.

As seen below at the boathouse cove. What's green is winged euonymus (mid-Spring).

Despite its invasiveness, it's still purchased and planted as an ornamental, as seen below.

Now, invasive species stream in online  Indeed, online sales of such noxious weeds - some of them illegal - have flourished so much in the past few years that the federal government is preparing a high-tech crackdown.

National Dam Safety Program: New Jersey
Emergency Action Plans developed in the area of the August 12, 2000 severe rainfall event
"On August 12, 2000 parts of northern New Jersey experienced an unusually heavy rainfall event which caused damage to approximately 24 dams with four dams being completely washed out. Four dams in the area including Swannanoa Lake #1 Dam, Swannanoa Lake #2 Dam, Mount Paul Dam, and Morris Lake Dam all had Emergency Action Plan documents and inundation mapping prepared and on file with the New Jersey Dam Safety Section. The Dam Safety Section, New Jersey State Police Office of Emergency Management, and the Federal Emergency Management Agency used these documents during the August 12, 2000 storm and aftermath."

Association of State Dam Safety Officials
ASDSO is a national non-profit organization of state and federal dam safety regulators, dam owners and operators, engineering consultants, manufacturers and suppliers, academia, contractors and others interested in dams safety. Our vision is to lead the US dam safety community with a strong, unified voice and effective programs and policies toward the furtherance of dam safety.
