Notes: (1) Angler hours for the month of July 2001 ore not additive as the result of deriving full. month data based on a formula with adual counts
made during the Test. (2) The low flow data were gathered doily during the Test; the previous year's data for the same week were only gathered two
times during the week and the weekend, so data comparisons would not be based on the same number of sampling days. 13) Comparison can only
be made on the total monthly dato and the catch rates. 14) There is no real explanation why July 1998 and July 2001 angler hours are higher thon
July 1999 and 2000. (5) The high catch rote for the regular waters in July 2000 is due to public knowledge of the stocking dote and place and the
resulting catch rate (being at the right place at the right time).
