Volunteer Lake Assessment Program Individual Lake Reports BERRY BAY, FREEDOM, NH MORPHOMETRIC DATA TROPHIC CLASSIFICATION Watershed Area (Ac.): 230,326 Surface Area (Ac.): 145 Shore Length (m): 5,800 Max. Depth (m): 11.6 Mean Depth (m): 3.7 Volume (m³): 2,147,000 Flushing Rate (yr¹) 254 P Retention Coef: -0.01 Elevation (ft): 406 Year KNOWN EXOTIC SPECIES Trophic class 1987 OLIGOTROPHIC 2003 MESOTROPHIC The Waterbody Report Card tables are generated from the DRAFT 2014 305(b) report on the status of N.H. waters, and are based on data collected from 20042013. Detailed waterbody assessment and report card information can be found at www.des.nh.gov/organizations/divisions/water/wmb/swqa/index.htm Designated Use Parameter Category Comments Aquatic Life Phosphorus (Total) Good The calculated median is from 5 or more samples and is < indicator and > 1/2 indicator and the chlorophyll a indicator is okay. pH Slightly Bad >10% of samples exceed criteria by a small margin (minimum of 2 exceedances). Oxygen, Dissolved Very Good There are a total of at least 10 samples with 0 exceedances of criteria. Primary Contact Recreation Dissolved oxygen satura Cautionary There are < 10 samples with 1 exceedance of criteria. More data needed. Chlorophyll-a Good The calculated median is from 5 or more samples and is < indicator and > 1/2 indicator. Escherichia coli No Data No data for this parameter. Chlorophyll-a Very Good There are a total of at least 10 samples with 0 exceedances of indicator. BEACH PRIMARY CONTACT ASSESSMENT STATUS BROAD BAY - CAMP ROBIN HOOD BEACH Escherichia coli Very Good Where there are no geometric means, all bacteria samples are < 75% of the geometric mean. Where there are geometric means all single bacteria samples are < the SSMC and all geometric means are < geometric mean criteria. LEAVITT BAY - CAMP MARIST BEACH Escherichia coli Very Good Where there are no geometric means, all bacteria samples are < 75% of the geometric mean. Where there are geometric means all single bacteria samples are < the SSMC and all geometric means are < geometric mean criteria. BROAD BAY - CAMP HUCKINS BEACH Escherichia coli Cautionary There are no geometric means and there is one single sample exceedance. More data needed.
