A fish population and fish species count shall l

A minimum of 16 net-nights' sampling will be accomplished each quarter.
At each sempling point two (2) sets of 2 net-nights' sampling will be obtained within i
30 days on a quarterly basis.
Spines, scale I
samples, and length / weight frequencies shall be obtained for representatives of each species.
4
b 4-11 I
Frequencies of sampling were ch'osen to obtain a j
trend of aquatic life in the area.
Most fish surveys are set up to be conducted in the summer because the fish are more plentiful at this time of year.
It is felt that more frequent sampling of the organisms would produce repetitive data.
However, less frequent sampling might yield erratic data from which no trend could be detected.
2 The' data will be evaluated in relation to preoperational data obtained by AP&L, UALR, Ark. Tech., and various g'overnmental agencies.
By comparing preoperational data with postoperational data, changes in the environ-ment can be detected.
It is felt that in this way
{
effects on the aquatic life by ANO can be monitored and controlled.
