A DRAFT CLASSIFICATION OF NATURAL FRESHWATER LAKES AND PONDS IN NEW HAMPSHIRE December 30, 2015 3 ACKNOWLEDGEMENTS We thank the following biologists who provided comments on the classification framework for lake and pond systems in NH: Matt Carpenter, Sandy Crystall, Joann Hoy, Sara Steiner, and Barry Wicklow. The purpose in classifying the lakes was to (1) evaluate actual water-quality and eutrophic conditions, (2) estimate the percentage nutrient contribution from various sources of eutrophication, and (3) evaluate potential nutrient-enrichment sources. As such, the water levels will be influenced by the climatic oligotrophic or mesotrophic in status (Figure 3.1). Lakes are classified on the basis of a) Origin b) Trophic levels c) Mixing of water. Classification suggests that it makes sense to place lakes into categories with management strategies best suited to the types of lakes found in each category.

A lake’s ability to support plant and animal life defines its level of productivity, or trophic state. Classification of the lakes The purpose of the classification was to create lake cluster classifications according to the principle that each cluster was to have a fish species composition of its own particular type, so that each composition was to differ from all the others. Houston Engineering Inc. 6901 E. Fish Lake Road, Suite 140 . A lake is a large body of natural water accumulated in a depression. A lake (from the Latin word lacus) is an inland body of water, not part of the ocean, that is larger and deeper than a pond and is localized at the bottom of a basin. the more intensive lake studies, yielded information necessary to structure a classification system for lakes in Washington.

Different fish species respond differently to water quality and habitat changes within a lake environment. There is, however, a lack of consensus on definitions used to distinguish between lakes and ponds. The stratification in a lake is not always the result of variation to density because of thermal gradients. In total, 5,950 lakes were classified into 15 lake classes using a two-tiered approach. River types are determined … The purpose in classifying the lakes was to (1) evaluate actual water-quality and eutrophic conditions, (2) estimate the percentage nutrient contribution from various sources of Lake – Classification of Lakes Lakes are among the most varied features of the earth’s surface.

In the fields of geology, physics and chemistry the classification is commonly based on the salinity of lake waters, hydrochemical types, saline mineral associations, mode of occurrence of lakes, relation and volume ratio of solid phase to liquid phase, origin of lake basins and useful minerals within the saline lakes (Jones et al., 1965; Eugster et ai., 1978).

For example, lakes can be classified to apply varying shoreland development standards. Lakes are commonly classified based on their productivity. Meromictic lakes have layers of water that do not intermix.
