Q:         I am traveling, and there is no keilim mikva in this area.  May I tovel new utensils in a lake or river?

 

A:         Metal, glass and glazed ceramic utensils which are purchased from a non-Jew and are used in the preparation and consumption of food require tevilah before use.1   A person may tovel utensils in “spring water” - water that flows naturally from under the ground.  If a river has such water as its source, he can tovel his utensils in the river.2   The river must contain at least forty se’ah of water, which calculates as 175 gallons of water.3   An ocean or sea is halachically considered to be “spring water”.4   Therefore, a person may tovel utensils in an ocean, sea, or river which has such water as its source.  However, regarding a river which has “spring water” as its source, if it has recently rained so heavily that there is a possibility that there is more rain water (and rain water runoff) than spring water present in the river, he cannot tovel utensils at that time.5

 

A person may tovel utensils in a naturally occurring lake or in a man-made lake which has naturally filled with rain water.6   As with spring water, the lake must contain at least 175 gallons of water.7   However, there is a major difference between tevilah in spring water and tevilah in a lake.  Although tevilah in spring water is permissible when water is flowing, tevilah in a lake is valid only when the water is stagnant.8  

 

It is common for lakes to have drainage pipes in order to prevent water from overflowing when it rains.  When water is draining through those pipes, the water above the pipes is not stagnant; whereas, the water below the pipes is stagnant.  If there are 175 gallons of stagnant water below the pipes, a Sefardi may tovel his utensils in all the water in the lake,9  including the water above the pipes.10   However, an Ashkenazi cannot tovel his utensils in any of the water in the lake,11  including the water below the pipes.12  

 

A person may not tovel utensils in a man-made lake which had been filled with water that was piped in from a nearby water source.13   It can be hard to find out how a lake was filled, and difficult to ascertain that no drainage is taking place, so a person should avoid performing tevilas keilim in a lake without first investigating these issues.

 

To summarize:  A person may tovel utensils in an ocean or sea.  If it has not rained heavily recently, he may also tovel utensils in a river which has an ocean or sea as its source, or a river which flows naturally from under the ground.  He should not tovel utensils in a lake without first investigating how it was formed; an Ashkenazi would need to investigate the drainage issues, as well.
