Reality:
I keep Stocking Records for Alberta. They are available here:
https://open.alberta.ca/publications/fish-stocking-list
However- I keep the records longer than shown above.
Date - # stocked - length in CMS
2003 - 132000 10
2004 33000 8 31900 17 Dual Stocking
2005 132000 10
2006 132900 10
2007 133000 10
2008 50000 8
2009 43000 11
2010 30000 15
2011 32000 17 26800 18 Dual Stocking
2012 15300 17 14700 18 Dual Stocking
2013 0
2014 5000 14.1
2015 5000 22.6
2016 5000 17.3
2017 5000 17.3 Winterkilled 2017>2018 winter - ACA failure
2018 2750 20.3 2250 16.4 Dual Stocking
2019 5000 20.3
2020 5000 19
Obviously in 2013 there was a change in philosophy with a stocking of 0.
However, the trout live for <> 5 years so the 2011 & 2012 would have still impacted food resources. The winterkill of 2017 finally got the lake on track to raise larger fish as evidenced this year.
As far as Govt or ACA/ The ACA is only involved because Parks who has both electrical outlet at the lake and spray aerators will not use them. Blame the Govt - you bet!
