From a Patoka Walleye site:

For anyone who might be interested in what went on with the walleye program this year in Indiana, here's the latest from the DNR on Patoka Lake and others:

Patoka: The first walleye stocking since 1978 occurred in 2008. In 2008 and 2009, there were 5.3 and 8.4 million walleye fry stocked. A total of 20 walleye were sampled that ranged in length from 5.3 to 11.6 inches. All were assumed to be age 0. The catch rate was 10.0/electrofishing hour, while in 2008 it was 18.0/hour. Catches in 2009 would probably have been higher if the lake had not been high and turbid. The stocking can be considered a success as it met the 7.0/electrofishing hour success criteria.

In 2010, a total of 13 walleye were collected. They ranged in length from 6.1 to 14.4 in. Eleven of the walleye collected were age 0. The age 0 electrofishing catch rate was 6.2/hr. The catch rate in 2009 was 10.0/electrofishing h. The catch rate most likely declined due to the reduced number of fry stocked. In 2010, 3.7 million fry were stocked compared to 8.4 million in 2009. The stocking can be considered successful, even though it did not quite reach the 7.0/electrofishing hr success criteria due to the reduced expectations with only 3.4 million stocked compared to a normal stocking rate of 8.8 million.

This year (2011), during the fall evaluation of the walleye stocking at Patoka Lake we collected 7.0 young of the year/hour and 6.0 age-1 walleye/hour.
