![]() ![]() Bill Goodwin has been the volunteer coordinator for the Dublin program since its inception. The Hosts are trained to monitor all launchings, especially if trailer hitches and motors are involved, since invasive weeds can be hidden in crevices and carried into an uncontaminated body of water. (Turns out it’s damaging, as well as illegal, to uproot anything growing on the lake bottom: pulling up “good” weeds creates an opening for “bad” ones to settle in the illegal part is that land from water’s edge inward belongs to the state and not to an individual so any action taken there is trespassing.)Īt the Boat Launch, we’ve got summer Lake Hosts (as do many other boating destinations in the state). If any are found, it is essential that they be reported immediately to Concord for expert handling. More volunteers, currently headed by Dede Clark, check visible underwater areas via kayaks, wading and snorkeling, looking for invasive weeds. Findings are sent to volunteers in town (currently John Morris and Joan Griffin), the Town Health Officer and the Selectmen. Once each season a biologist from NH Department of Environmental Services does additional tests and sampling that contribute to information about the lake’s overall health.

In summer, at the two swimming club beaches and the boat launch, sampling is done monthly for E. Paving, drainage culverts, sand and salt - all that maintenance for safe driving - creates runoff that washes oil, grease, dirt, sand and sodium chloride into a lake or pond.Īt Dublin Lake, water is collected by volunteers and taken to the Department of Environmental Science laboratory in Concord for analysis. What’s dangerous is a non-native weed such as the variable milfoil (found in many aquariums) that was discovered a few years ago in Cemetery Cove (and was immediately covered with a smothering mat).Īs for roads, what’s needed to keep them in good shape runs directly counter to what’s good for an adjacent body of water. If a lake has aged to the wrinkly warty place where weeds are established, it’s important to know that some species such as the tall pipewort in Dublin Lake are associated with good water quality. Fertilizer applied to any land that drains toward a lake/pond “nourishes” the underwater area so more and more weeds grow and eventually fish and other water creatures can’t get enough oxygen. Storm runoff washes any and everything into a lake – dirt, chemicals, fecal matter. The main local hits on a body of water are storm water runoff, lawn and garden fertilizing (nitrogen and phosphorus), roads, invasive weeds and failing septic systems. (Too much acid endangers fish and the tiny water organisms necessary for lake wellbeing.) Some activity, such as acid rain caused by smoke from Midwestern power plants, is not a regional matter and the damage is not visible except in water samples that measure acidic levels. What’s lumped together as ‘human activity’ is the biggest challenge to water quality. The recommendations for lake TLC are not just for Dublin, but also for bodies of water throughout the state. New Hampshire has approximately 1,000 lakes and ponds, covering some 165,000 acres, and water scientists have accumulated enormous amounts of information over many years. Tim clark pocket for mac skin#The visible signs – the ones like wrinkled warty skin in humans, or loss of height and appetite – those are showing up in increasing weed growth, warmer and murkier water, disappearing crayfish, and in August of this year a bloom of cyanobacteria.Īs with any valuable antique, special care and handling are needed.

The lake is a draw for swimming, walking-around, fishing, boating, diving, fireworks and sunset gazing. Down at water level, the three-mile circumference is an identifier for part of town and a regional landmark for tourists and other travelers.
