Get Term ID from URL
Basically you would have to do:

$path = current_path();
$path_array = explode('/', $path); // Doing this you would get the array of all the elements that there in the url.


Once you have the array of items in the array, you would have to do

$term_name = $path_array[1];


So in $term_name you would have lakename, which is your term name.

Once you have the name, simply do

$term_object = taxonomy_get_term_by_name($term_name);


$term_object would have the object of the term.
