Chautauqua in the spring of 1950, fig. 7, amounting 
to 32.1 per cent of the catch. The best period of 
fishing for streakers was from the last week in April 
through the middle of May. In 1951, the last week 
in April was the only good week of yellow 
bass fishing. 
In both years the best fishing for yellow bass 
occurred during periods of high water. Most of 
these fish were caught on worms near Burr Oak 
Island at the upper end of the lake. 
A graph of the distribution of sizes of yellow 
bass caught by anglers suggests that this species 
does not spawn successfully each year, fig. 19. 
This species is pictured in fig. 20. 
White Bass 
The white bass, fig. 20, is one fish at Lake © 
Chautauqua and nearby waters that may be caught 
very successfully on artificial lures. This fish is 
new to some central Illinois anglers and when taken 
by them is often confused with its relative the 
yellow bass, fig. 20. 
The white bass has been abundant in Lake 
Chautauqua and neighboring waters since 1950. 
Evidently water conditions in the Havana section 
of the Illinois River were favorable for the spawn- 
ing of white bass, as they appeared in the river 
and in Lake Chautauqua in 1950 and 1951 in 
larger numbers than had been seen there previously.
