NOTICE of a Free Workshop

The issue:  Prevent the risk of cyanobacteria blooms in Mirror Lake by reducing the level of phosphorus.

How?  Slow the flow of storm water run-off which carries phosphorus loaded sediment into Mirror Lake.

What?  A free workshop to teach participants ways to beautify their property while protecting Mirror Lake’s water quality.

When?  Saturday, July 20th, 9:00 am to 11:00 am at Mirror Lake Community Church  (where Tuftonboro Neck Road intersects Governor Wentworth Highway – Route 109 north).

RSVP – Please indicate your interest in attending ASAP as we may open it to the public, space permitted.  Please respond to the “Contact Us” page of this web site if you are planning to attend the workshop.

More Details:  The workshop will teach homeowners how to apply “low impact development”(LID) storm water management practices on their properties by using attractive native plants and promoting soil infiltration. Bob Hartzel of Geosyntec Consultants will provide an overview of LID concepts and step-by step guide to building rain gardens,  “bioretention cells”, porous pavers, rain barrels, and other LID landscaping techniques that use native shrubs, annuals and perennial flowers.

Bob Hartzel is a Certified Lake Manager (CLM) and wetland scientist with over 20 years of experience in managing lake, river and wetland restoration projects. Bob is also a Certified Professional in Erosion and Sediment Control and led a variety of recent projects implementing Low Impact Development (LID) stormwater techniques in New England watersheds.

The workshop is sponsored by Mirror Lake Protective Association with funding provided by a Section 319 Federal Clean Water Act grant administered by New Hampshire Department of Environmental Services.

Water Quality

The Mirror Lake Protective Association (“MLPA”) has been involved with protecting the quality of water in Mirror Lake since 1991. Water quality is an important issue for all residents and wildlife in and around any body of water and should always be taken into consideration. Contaminated water can lead to health issues as well as environmental problems. To ensure you are not directly polluting surface waters in New Hampshires, follow these simple tips:

  • Design your septic system according to DES rules and maintain and inspect the pump every 2-3 years
  • Cultivate a wooded shoreline buffer
  • Use only phosphorous free fertilizer
  • Minimize paving or reroute stormwater to reduce runoff
  • Use non-phosphate cleaning supplies
  • Do not bathe or wash pets in water
  • Do not allow farm animals in Mirror Lake or the inlets that run into Mirror Lake
  • When you replace your outboard boat motor, choose a clean 4-stoke engine
  • When boating in shallow areas or along shoreline, minimize wake
  • Always check boat, trailer and equipment for plant fragments
  • Support the MLPA and regional lake associations!

In general terms, a watershed is an area of land upstream of a water body (a point in a stream or the outlet of a lake) in which all the surface of the water drains to the water body. A watershed is delineated by starting at the point in a stream or the outlet of a lake and following the highest elevation of land that divides the direction of flow until returning back to the point or outlet.

Watershed Management Plan

October 24, 2011:  Nancy Byrd and Bob Craycraft of UNH are seeking volunteers to help take soil samples from the spray fields at the Wolfeboro Wastewater Treatment Facility this Friday at 11:00 AM.  Please contact Nancy Byrd  nancy@pangean.com if you can help.  You will recall that the spray apparatus has been removed from the spray fields in Mirror Lake’s watershed.  However, the modeling predicts that 2 lbs of phosphorus will continue to runoff those fields for the next 10 years.  This analysis will help MLPA refine this projection.  Dusty Davies, President, MLPA
