C# -- trying to add dataset row from one dataset to another -- ERROR: This row already belongs to another table.

I have a dataset with lets say ten rows.  I am trying to loop through the dataset and find those that have the first column equal to 'ABC' and add those to another dataset.  Refer to my code below.  I receive the error 'This row already belongs to another table'.   I need to create a separate dataset as I am needing to use the data somewhere else.

foreach(DataRow dr in dsAll.Tables[0].Rows)
{
if (dr[0].ToString() == "ABC")
{
    dsQuery.Tables[0].NewRow();
    dsQuery.Tables[0].Rows.Add(dr);
}
}

Thanks
