Lake Preservation Committee Makes Recommendations to BOS

The Dublin Lake Preservation Committee has recommended to the Board of Selectmen that several steps be taken to protect and improve water quality in Dublin Lake:

(1) Maintain and clean the catch basins. The majority of sediment and other pollutants are carried via streams (some intermittent) into the Lake during heavy rains and spring melt. Volunteer weed watchers and water testers have observed that Lake beds near culverts are muddy, an indication of runoff-carried sediment. Visual inspection of catch basins show that many are full of sediment and other debris. During big downpours, the sediment overwhelms the basins; this situation is likely to continue. Nonetheless, the basins must be properly maintained and cleaned regularly to be effective.

(2) Reduce the amount of road salt used in the Watershed area. Although the Lake is generally in good health, tests show Dublin Lake has higher-than-expected conductivity (a measurement of water quality) and high levels of sodium chloride (road salt). (For more on conductivity, see: http://www.water.epa.gov/type/rsl/monitoring/vms59.cfm)

(3) Restore the buffer zone. This zone was established to provide a filtering area between the Lake and the roads around it. Over the years, the zone’s width has been significantly reduced; it should be restored to improve filtering of runoff.

(4) Continue outreach to property owners within the Watershed. Mailings and presentations should be used to enlist property owners’ support in controlling runoff from their land, reducing fertilizer and salt use, and properly maintaining their septic systems.

Oil spill near Dublin Lake

Between 50 and 75 gallons of diesel fuel spilled from a 2007 International tractor-trailer truck on Monday, March 4 when it crashed into a stonewall near the Dublin Town Cemetery on Route 101.  The driver said snowdrifts across the road caused his vehicle to skid.

The fuel tank ruptured when it struck the stonewall. The accident shut down both lanes of travel on Route 101 for nearly two hours. The driver was not injured and no other vehicles were involved in the crash.

The crash was near Dublin Lake, but town officials say the spill was quickly contained and did not leak into nearby waters.

First responders quickly contained the fuel spill with Speedy Dry, which is similar in texture to cat litter and absorbs petroleum.  An environmental clean-up crew from Clean Harbors of Norwell, Mass., responded to the crash scene Monday night and returned Tuesday morning to assist the town, and  N.H. Department of Environmental Services was also on scene Tuesday.

Natural Resources Inventory

The Board of Directors commissioned a Natural Resources Inventory in 2009 to identify important populations ~ bird, mammal and plant ~ that needed to be taken into consideration as plans for using Beech Hill were developed.  Cynthia Nichols, M.S., and colleagues at Antioch New England conducted the survey.

~ Birds ~

Ken Klapper conducted the bird surveys.  He noted that Beech Hill has a rich and diverse bird population using its varied habitats.  Overall,  he identified 46 species  ~ breeders, residents and migrants ~ on the property during the survey period.  Sixteen of these are marked with an asterisk because they are experiencing significant population declines in New Hampshire.  According to a 2010 report, The State of New Hampshire’s Birds,

“These include shrub land and grassland birds, as well as a whole suite of “aerial insectivores” — birds, like swallows, that feed on the wing. Of our forest birds, roughly as many are increasing as are decreasing, and many of the latter are species that require larger tracts or forest or that migrate out of the state during the non-breeding season. Land protection and careful planning can minimize the habitat effects here in the Granite State, but it will be equally important to maintain a larger perspective if we are to ensure that migratory species successfully return to nest here each summer. Other causes of declines can include increased predation, chemical contaminants, and the uncertain effects of climate change.”

List of species:

Eastern Bluebird
Black-Capped Chickadee
Brown Creeper
Brown-Headed Cowbird*
American Crow
Mourning Dove
Purple Finch*
Northern Flicker*
Great Crested Flycatcher
American Goldfinch
Rose-Breasted Grosbeak*
Ruffed Grouse*
Cooper’s Hawk
Blue Jay*
Dark-eyed Junco*
Eastern Kingbird*
White-Breasted Nuthatch
Eastern Phoebe
Ovenbird
Barred Owl
Common Raven
American Redstart*
American Robin
Yellow-Bellied Sapsucker
Pine Siskin
Chipping Sparrow
Chimney Swift*
Scarlet Tanager*
Hermit Thrush
Wood Thrush*
Tufted Titmouse
Veery*
Red-Eyed Vireo
Blue-Headed Vireo
Blackburnian Warbler
Black and White Warbler*
Black-Throated Blue Warbler
Black-Throated Green Warbler
Chestnut-Sided Warbler*
Nashville Warbler
Pine Warbler
Yellow-Rumped Warbler
Downy Woodpecker
Hairy Woodpecker
Pileated Woodpecker
Eastern Wood-Peewee*

~ Mammals ~

Matt Walter conducted the inventory of mammals in the winter.  Year-round residents on Beech Hill include:  Chipmunk, White-tailed Deer, Fisher, Red Fox, White-Footed Mouse, Porcupine, and both Red and Gray Squirrels.  Hikers have since reported seeing evidence of Bobcat and Black Bear.

~ Vegetation ~

Cynthia Nichols and Bonnie Hudspeth did the Vegetation Inventory.  They noted that Beech Hill has a Northern Hardwood Mature Forest Matrix, meaning that the forest is well-established and mature, a rather rare combination in this part of New England.    They also noted that, in addition to providing magnificent views to the north and east, Eagle Rocks support many small-bush blueberries and well-established crevasse communities on the granite.  The latter are extremely delicate and should be protected.

They described the area adjacent to the cell towers as being “open upland grassland habitat with midstory shrub edges,”  which is considered to be good wildlife habitat.  This kind of habitat is somewhat rare in New Hampshire.  If it is maintained as a shrubby field, it might attract brush-loving species such as the Eastern Towhee, Brown Thrasher and Field Sparrow.  Given that other edge or shrub birds were found in the avian survey, this area may have moderate attraction for new shrubland species, many of which are in serious decline in New Hampshire.

The rocky ridge on the northeast corner of the property has strong potential as a fall migratory hawk survey site.  The large field area also might offer good visibility for observing hawk migration, especially if a tower or viewing platform were installed.

New NH Shoreland Protection Regulations

New Hampshire has passed new Shoreland Protection regulations that we will post  when we get them.  Everyone who has property on the Lake (or any other body of water) may be affected by these regulations.
