Climate change is weakening New Hampshire’s waterways



New Hampshire has about 1,000 lakes and ponds and thousands of miles of rivers and streams, but global warming is starting to threaten some of them and that could mean big changes in how we interact with our freshwater resources. So many granite staters enjoy swimming, fishing, and boating in lakes, ponds, and rivers. But as the climate gets warmer, scientists are seeing negative impacts on New Hampshire’s freshwater ecosystem, we’re seeing an increase in cyanobacterial blooms in New Hampshire and that’s likely the cause *** of the nutrients and temperatures. Ecotoxicology specialist *** Amanda McQuade says bacteria are becoming more prevalent in our lakes and ponds and will continue to do so. We might expect an increase in cyanobacteria in New Hampshire if we see significant increases in warming temperatures as the temperature rises. We are also seeing more storms with higher amounts of precipitation. The average and conquered annual rainfall over the past 30 years is greater than any previous 30-year period since the beginning. Second, as New Hampshire Lakes President Andrea Lamoreaux suggests, this higher number plays a *** role in increasing the amount of bacteria in New Hampshire lakes. When we have these bigger storms, we have more water flowing off the landscape and washing away the pollution and soil leaching and that pollution and soil getting into our lakes and basically helping bacteria grow. There are a few small steps that every landowner in New Hampshire can take to help combat the addition of soil and pollution that enters our lakes, such as Bamboo Stick Lake and. Amherst, you know, do simple things on your property, like, you know, have lots of vegetation to soak up rainwater and hold the soil in place. These are simple things anyone can do uh, to help minimize that polluted runoff water, invasive plants like milfoil are also becoming more common as the warmer water provides a good *** environment for the growth. As our climate gets warmer, you know, like down south, some of these plants and animals will start surviving here in our lakes, causing all kinds of ecological problems. Speaking of animals, as the water temperature rises. Freshwater fish in New Hampshire also face challenges, as John Magee fish, habitat biologist at New Hampshire Fish and Game Forecasts, streams and lakes can become unsuitable for freshwater fish. cold. We are particularly interested in wild brook trout, essentially. In some places, they are very likely to go away, the water will become too hot for them and these populations will simply disappear. Uh, at *** minimum, populations will be reduced according to *** many of the model’s predictions. We can expect drier summers and longer periods without thunderstorms. Recent dry patches are already having an impact. We’ve done *** a lot of work where we’ve done our standard fish surveys and we go back to *** stream *** a few years later and it’s completely dry the years just before there was that * * very strong, you know, apparently healthy population of wild brook trout, but all is not lost. New Hampshire Lakes says you can do little things like add native plants to your garden, and if everyone makes small changes, it will have a significant impact.
