we need a ramsey lake watershed study

2
Under Review (2013): 135 units proposed for the South Peninsula off Keast Drive A Watershed Study will tell us: • how to maintain existing wetland and floodplain. Climate change will bring more extreme weather events so wetlands and floodplains are crucial for clean water protection. Stormwater runoff should not be directed through natural wetlands. • the consequences of damage to natural features. A significant stream, leading to fish habitat, and an established forest are set to be altered which will increase erosion, especially from the steep heights of this land, and harm fish habitat. ACT NOW. . .WHAT CAN YOU DO? Your city wants to hear from you with your concerns Call the city planning department at 311 Talk to your city councilor Talk to your family, friends and neighbours ASK FOR A WATERSHED STUDY FOR RAMSEY LAKE To find out more, contact Lilly Noble, CoChair Ramsey Lake Stewardship Committee Ramsey Lake Stewardship Committee (705) 6915538 Join our group [email protected] or visit our website. 50% recycled paper CAN THE RAMSEY LAKE WATERSHED SUPPORT MORE DEVELOPMENT? WE WE ALL ALL DEPEND ON THE LAKE: DEPEND ON THE LAKE: Ramsey Lake is a source of 40% of Sudbury’s municipal and private drinking water and enjoyed by organizations and individuals for recreational activities such as boating, swimming and fishing. Consider the cost to Sudbury if we were forced to find an alternative source of drinking water! (Photo: Proposed development area off Keast Drive looking north toward the Bethel Lake wetland) YET, NO WATERSHED STUDIES HAVE BEEN DONE YET, NO WATERSHED STUDIES HAVE BEEN DONE: *The Ministry of the Environment states “urban development without watershed/subwatershed planning is discouraged…” (MOE Guidelines) *Dr. John Gunn (Vale Living with Lakes Centre) urges us “. . . to insist that drinking water be protected or lakes be protected. . . [OR, IF WE DO NOT]. . . we’ll lose the use of our waters more and more frequently.” (Sudbury Star, Oct. 13/12) *Dr. David Pearson cautions us to make considered decisions: “Restricting development in a tailored fashion on the lake is the only way to protect water quality.” (Northern Life, Feb. 28/13) WE NEED WATERSHED STUDIES NOW BEFORE IT’S TOO LATE! A watershed study can tell us: (1) The major sources of phosphorus and other pollutants entering the lake; (2) Their effects are on our drinking water, fish habitat, ecosystem and recreation; (3) What we can do to reduce their entry into our lakes.

 WARNING  SIGNS:    1.Public  Beach  Closures:  In  the  summers  of  2008,  2010,  2011  

and  2012  (July  28  –August  5)  due  to  blue-­‐green  algae  blooms  that  produce  cyanobacteria  toxins    (Sudbury  and  District  Health  Unit)  accompanied  by  advisories  for  lakeside  residents  with  lakewater  intakes  not  to  use  lake  water  for  drinking  or  bathing.      

(Blue-­‐green  algae  bloom  along  the  Lake  Ramsey  shoreline)    2.  Higher  phosphorus  levels  lead  to  blue-­green  algae  blooms:    a)  Phosphorus  levels  from  selected  samples  have  varied  in  the  past  8  years  from  as  high  as  15.6  micrograms/Litre  in  2005  to  7.5  in  2012.    For  the  spring  run-­‐off  periods,  the  average  phosphorus  level  was  10.1  micrograms/L  over  the  last  9  years.    What  is  protective  for  the  lake?    Lower  than  10  micrograms/L.        b)  Points  of  entry  of  phosphorus  into  the  lake:    Phosphorus  reaching  Ramsey  Lake  from  Frobisher  Creek  were  measured  as  78.9  micrograms/L  in  2009  and  110.5  in  2010.  The  stream  leading  to  Ramsey  Lake  from  Bethel  Lake  had  readings  of  353  and  136  micrograms/L  phosphorus  in  the  fall  of  2010.    Levels  flowing  into  Ramsey  Lake  from  Minnow  Lake  were  also  at  these  higher  levels  in  the  spring  and  fall  (Bradley,  J.  M.Sc.  thesis).    High  readings  in  the  Bell  Park  storm  sewer  add  to  the  urgency  for  a  thorough  sub-­‐watershed  studies  are  needed  in  these  areas.    3.  Climate  change:  The  average  mean  temperature  in  Sudbury  has  increased  from  3  degrees  C  in  1955  to  about  4.5  degrees  C  in  2010  (Vital  Signs  Report,  City  of  Lakes  Edition).    According  to  Dr.  Pearson,  “Ramsey  is  on  a  knife  edge”  of  becoming  overwhelmed  with  algae  blooms  (Northern  Life,  Feb.  28/13).    4.  Other  lake  contaminants:  An  elevated  sodium  level  of  53  mg/L  was  found  in  2009  and  is  steadily  increasing.  Note  that,  at  levels  above  20  mg/L  the  health  unit  must  be  notified  so  that  local    

 physicians  and  patients  can  be  informed.    (Sudbury  &  District  Health  Unit).  Salt  levels  will  increase  with  all  new  roadways  built  in  the  watershed.        5.  Shoreline  already  disturbed  or  damaged:  21-­‐25%  of  the  populated  shoreline  (Ramsey  Lake  Report  Card).    Enforcement  of  existing  bylaws  for  shoreline  buffer  zones  on  lakefront  properties  is  required  along  with  efforts  to  increase  the  required  buffer  area.      Top  3  Priorities  for  Watershed  Studies  in  the  2006  Official  Plan  of  the  City  of  Greater  Sudbury:  1)  Nepahwin/Robinson;  2)  Ramsey  Lake;  3)  Whitson  River  Lake  Nepahwin  was  assessed  and  cleaned  up  only  after  the  Federal  Department  of  Fisheries  and  Oceans  directed  the  city  to  act.    Let’s  be  proactive  with  Ramsey  Lake  and  get  a  watershed  study  done  sooner  than  later.    Pressures  on  Watersheds  from  Urban  Run-­Off    A  watershed  study  on  Lake  Simcoe  showed  the  built  environment  to  be  a  major  source  of  phosphorus:  (1)  31%  from  urban  runoff  and  stormwater;  2)  27%  from  atmospheric  deposits  partly  from  wind  transport  of  disturbed  soils  that  come  from  land  stripped  of  plants  during  construction;  3)  25%  from  farming  and,  4)  only  6%  from  septic  systems  on  lakeside  properties.    Urgency  for  a  Study  of  the  Ramsey  Lake  Watershed:  Already  approved:  1000  new  units  in  the  watershed.      Stormwater  from  these  developed  areas  will  need  to  be  properly  cleaned  using  the  best  possible  stormwater  treatment  to  ensure  phosphorus  levels  and    water  temperatures  do  not  rise,  and  pollution  is  minimized.  Will  it  be  done?                                (Proposed  developments  in  red.)    Let’s  not  guess.
