Like the article posted suggests the Green is much more wadeable in Green County. There are some stretches in Hart County but its not overly accessible in Hart County and by the time you reach Mammoth Cave it starts getting deeper due to the old locks in Edmonson County. Green is an excellent smallmouth and rockbass fishing river. You might try Little Barren in Green and Metcalfe County, The Barren River off Hwy 100 from Smiths Grove (Martinsville Ford area) on Warren/Allen County line. Maybe the Green there in Munfordville at Wilma Stoval Park under the Green River Bridge.
