BACK-WATER. That water in a stream which, in consequence of some obstruction 
below, is detained or checked in its course, or reflows. 
     2. Every riparian owner is entitled to the benefit of the water in its 
natural state. Whenever, therefore, the owner of land dams or impedes the 
water in such a manner as to back it on his neighbor above, he is liable to 
an action; for no one has a right to alter the level of the water, either 
where it enters, or where it leaves his property. 9 Co. 59; 1 B. & Ald. 258;
