New Jersey wasn’t the only state impacted by HABs. The increase caused severe impacts on lakes throughout the country, resulting in beach closures, restricting access to lake usage, and prompting wide-ranging health advisories. In November, New Jersey Governor Phil Murphy and officials from the New Jersey Department of Environmental Protection (NJDEP) announced a three-pronged, $13 million initiative to reduce and prevent future HABs in the state. As part of the initiative, NJDEP hosted its first regional HABs Summit with the goal of prevention by improving communication throughout lake communities and sharing information ahead of the warmer months when HABs begin to appear. The summit, which was held on January 28, 2020 at NJDEP's Pequest Trout Hatchery and Natural Resource Education Center in Warren County included a Q&A panel discussion, information resource tables for one-on-one discussions, and presentations from a variety of NJDEP representatives and environmental experts. Princeton Hydro's Director of Aquatics and regional HABs expert Dr. Fred Lubnow’s presentation focused on how to properly and effectively manage HABs. According to Dr. Lubnow, “Managing loads of phosphorous in watersheds is even more important as the East Coast becomes increasingly warmer and wetter thanks to climate change. Climate change will likely need to be dealt with on a national and international scale. But local communities, groups, and individuals can have a real impact in reducing phosphorous levels in local waters.” In a recent press release from Governor Murphy’s office, the NJDEP Chief of Staff Shawn LaTourette said, “We will reduce HABs by working closely with our local partners on prevention and treatment techniques, while relying on the best available science to clearly communicate risk to the public. Our new HABs initiative will enhance the Department’s ability to evaluate statewide strategies and increase the capacity of lake communities to reduce future blooms.” New Jersey’s new HABs initiative is comprised of three main components: Providing Funding: More than $13 million in funding will be available to local communities to assist in preventing HABs, including:

New Jersey’s new HABs initiative is comprised of three main components:
More than $13 million in funding will be available to local communities to assist in preventing HABs, including:
$2.5 million will be available as matching funds for lakes and HABs management grants, including treatment and prevention demonstration projects.
Up to $1 million in Watershed Grant funding will be made available for planning and projects that reduce the nonpoint source pollution, including nutrients, that contribute to HABs in surface waters of the State.
$10 million in principal forgiveness grants will be offered through the Clean Water State Revolving Fund for half of the cost, capped at $2 million, of sewer and stormwater upgrades to reduce the flow of nutrients to affected waterbodies.
Per the Governor’s press release, “the second element of the initiative is to build upon the state’s scientific expertise and enhance its capacity to respond to HAB events. This includes establishing a team of experts from across various sectors to evaluate the state’s strategies to prevent HABs and pursuing additional monitoring, testing and data management capacity.”
The third component is focused on increasing NJDEP’s ability to communicate with affected communities. The regional HABs Summit held on January 28 was one of two Summits that will occur in early 2020 (the date of the next Summit has not yet been announced). NJDEP has also developed new web tools to provide HABs education, offer a forum to discuss and report potential HAB sightings, and better communicate HAB incidents.

Climate change is an enormous concept that can be hard to wrap your head around. It comes in the form of melting ice caps, stronger storms, and more extreme seasonal temperatures (IPCC, 2018). If you’re an avid angler, photographer, swimmer, boater, or nature enthusiast, it’s likely that because of climate change you’ll bear witness to astonishing shifts in nature throughout the greater portion of your lifetime. This is especially true with respect to lakes.
Lakes are living laboratories through which we can observe the local effects of climate change in our own communities. Lake ecosystems are defined by a combination of various abiotic and biotic factors. Changes in hydrology, water chemistry, biology, or physical properties of a lake can have cascading consequences that may rapidly alter the overall properties of a lake and surrounding ecosystem. Most of the time the results are negative and the impacts severe.
"Managing loads of phosphorous in watersheds is even more important as the East Coast becomes increasingly warmer and wetter thanks to climate change," said Dr. Fred Lubnow, Director of Aquatics in a recent NJ.com interview. "Climate change will likely need to be dealt with on a national and international scale. But local communities, groups, and individuals can have a real impact in reducing phosphorous levels in local waters."
Recognizing and monitoring the changes that are taking place locally brings the problems of climate change closer to home, which can help raise awareness and inspire environmentally-minded action.
We put together a list of four inter-related, climate change induced environmental impacts that can affect lakes and lake communities:
The survival of many lake organisms is dependent on the existence of set temperature ranges and ample oxygen levels. The amount of dissolved oxygen (DO) present in a lake is a result of oxygen diffusion from the atmosphere and its production by algae and aquatic plants via photosynthesis. An inverse relationship exists between water temperature and DO concentrations. Due to the physical properties of water, warmer water holds less DO than cooler water.
This is not good news for many flora and fauna, such as fish that can only survive and reproduce in waters of specific temperatures and DO levels. Lower oxygen levels can reduce their ability to feed, spawn and survive. Populations of cold water fish, such as brown trout and salmon, will be jeopardized by climate change (Kernan, 2015).
Also, consider the effects of changing DO levels on fish that can tolerate these challenging conditions. They will thrive where others struggle, taking advantage of their superior fitness by expanding their area of colonization, increasing population size, and/or becoming a more dominant species in the ecosystem. A big fish in a little pond, you might say. Carp is a common example of a thermo-tolerant fish that can quickly colonize and dominate a lake’s fishery, in the process causing tremendous ecological impact (Kernan, 2010).
Just as fish and other aquatic organisms require specific ranges of temperature and dissolved oxygen to exist, they must also live in waters of specific salinity. Droughts are occurring worldwide in greater frequency and intensity. The lack of rain reduces inflow and higher temperatures promote increased evaporation. Diminishing inflow and dropping lake levels are affecting some lakes by concentrating dissolved minerals and increasing their salinity.
Studies of zooplankton, crustaceans and benthic insects have provided evidence of the consequences of elevated salinity levels on organismal health, reproduction and mortality (Hall and Burns, 2002; Herbst, 2013; Schallenberg et al., 2003). While salinity is not directly related to the fitness or survival rate of all aquatic organisms, an increase in salinity does tend to be stressful for many.
Phosphorus is a major nutrient in determining lake health. Too little phosphorus can restrict biological growth, whereas an excess can promote unbounded proliferation of algae and aquatic plants.
If lake or pond water becomes anoxic at the sediment-water interface (meaning the water has very low or completely zero DO), phosphorus will be released from the sediment. Also some invasive plant species can actually “pump” phosphorus from the sediments and release this excess into the water column (termed luxurious uptake). This internally released and recycled sedimentary phosphorus can greatly influence lake productivity and increase the frequency, magnitude and duration of algae blooms. Rising water temperatures, declining DO and the proliferation of invasive plants are all outcomes of climate change and can lead to increases in a lake’s phosphorus concentrations and the subsequent growth and development of algae and aquatic plants.
Rising water temperatures significantly facilitate and support the development of cyanobacteria (bluegreen algae) blooms. These blooms are also fueled by increasing internal and external phosphorus loading. At very high densities, cyanobacteria may attain harmful algae bloom (HAB) proportions. Elevated concentrations of cyanotoxins may then be produced, and these compounds seriously impact the health of humans, pets and livestock.
Phosphorus loading in our local waterways also comes from nonpoint sources, especially stormwater runoff. Climate change is recognized to increase the frequency and magnitude of storm events. Larger storms intensify the mobilization and transport of pollutants from the watershed's surrounding lakes, thus leading to an increase in nonpoint source loading. Additionally, larger storms cause erosion and instability of streams, again adding to the influx of more phosphorus to our lakes. Shifts in our regular behaviors with regards to fertilizer usage, gardening practices and community clean-ups, as well as the implementation of green infrastructure stormwater management measures can help decrease storm-related phosphorus loading and lessen the occurrence of HABs.
A lake ecosystem stressed by agents such as disturbance or eutrophication can be even more susceptible to invasive species colonization, a concept coined “invasibility” (Kernan, 2015).
For example, imagine that cold water fish species A has experienced a 50% population decrease as a result of warming water temperatures over ten years. Consequently, the fish’s main prey, species B, has also undergone rapid changes in its population structure. Inversely, it has boomed without its major predator to keep it in check. Following this pattern, the next species level down - species B’s prey, species C - has decreased in population due to intense predation by species B, and so on. Although the ecosystem can potentially achieve equilibrium, it remains in a very unstable and ecologically stressful state for a prolonged period of time. This leads to major changes in the biotic assemblage of the lake and trickle-down changes that affect its recreational use, water quality and aesthetics.

Although your favorite lake may not experience all or some of these challenges, it is crucial to be aware of the many ways that climate change impacts the Earth. We can’t foresee exactly how much will change, but we can prepare ourselves to adapt to and aid our planet. How to start? Get directly involved in the management of your lake and pond. Decrease nutrient loading and conserve water. Act locally, but think globally. Get out and spread enthusiasm for appreciating and protecting lake ecosystems.
