Code Overview: Lake Classification projects will be conducted by counties to study the characteristics of lakes and assign them into different management classifications for the purpose of implementing lakes-based protection activities. As a results, very shallow lakes are excluded this classification system. Due to the absence of intermixing of the water, the bottom layer of the lake contains no dissolved oxygen and is therefore largely devoid of life except for the purple sulfur bacteria. Lake basins are formed due to endogenous geological processes like tectonism and volcanism and exogenous activities like landslides, glaciation, solution, river and wind action. �H�%�������=�5��I|��Y"Y@�TM5���^�`4����]7�G��H��#��e&�J�����gxF�?-�����F��o�^�g���P*�:i�m���uK���poգ�;�v��&Nb�+\�#�xK��pT�=A���_� ���N%����Z�]�d.�Y\�HuVv�U�4��J�q�\`����Y��y�-l(�3EONY R.q���%['��w�͏� ���ه�R0u�$�q��L�DrR)�G�t����.��7�{��f�7�6�_�WnC�>f��(3K��4Y�YʬC�S�;��l Maple Grove, MN 55369 October 31, 2011 .

Whether a lake is small, big or very large. Clearly, the classification of lakes in the WFD must eventually be based on biological indicators, but TP is the main environmental stressor and the primary determining factor for numerous bio-logical variables, and it is also used in present-day lake classification (Vollenweider & Kerekes 1982; Wetzel 2001).

For example, lakes can be classified to apply varying shoreland development standards. Organic lakes are formed by the action of flora or fauna. A lake is a large body of natural water accumulated in a depression. Meromictic lakes have layers of water that do not intermix. The majority (383 or 85.3%) of the lakes examined in the period 2004-2006 were of satisfactory water quality, i.e. a flexible lake classification framework in collaboration with ~100 fisheries biologists for improved fisheries conservation man- agement in Wisconsin, USA.
