BeenThereDoneThat.
Wouldn't surprise me to hear the PFBC tried stocking "splake" at one time or another.
Them biologist love a good experiment....
This was part of an email a PFBC biologist sent me back in 2011, when I asked some questions about the trout program...
While Two Mile Run Reservoir is deep and has a small layer of cooler water with some oxygen it is not a classic two story lake with a large deep layer of very cold water with very high oxygen concentration conducive to trout such as occurs at East Branch Clarion River Lake. It is more of a borderline situation at Two Mile. Back in the early 1990's we tried stocking fingerling trout in Two Mile Run Reservoir and had very few trout make it through to succeeding years and attain larger size. A few larger trout are occasionally caught in the lake but for the most part our information indicates hold over potential is limited. I assume he is talking about Brook Trout at 2Mile, cause if you look at Keystone Lake in Armstrong, read the 2001 biologists report:
Keystone Lake
Spring sampling in 2001 at Keystone Lake (Armstrong/Indiana Counties) produced extremely positive results. Past stockings of brook trout have produced high numbers of brook trout ranging from 8 to 10 inches in length. Night electrofishing efforts verified the high numbers of brook trout as well as high numbers of rainbow smelt. The smelt were introduced in the late 1980's and early 1990's and are self sustaining. Spring night electrofishing produced high numbers of walleye as well. The majority of walleye ranged from 18 through 24 inches, however fair numbers of walleye ranging from 27 to 30 inches were also encountered. These walleye were without doubt some of the heaviest encountered during walleye sampling efforts over the past two decades.
Trapnet efforts continued to produce quality size walleye and legal brook trout. No smelt were observed during trapnet efforts. Seven tiger muskellunge were sampled by trapnet and they ranged from 708 through 1295 mm (27.8 - 50.98 inches). Four of the seven tigers were of legal size. Black and white crappie were just becoming active and some of the early anglers were doing well with fair numbers of crappie being present, including good representation in the 9 to 13 inch size groups. Bluegill were not present in high numbers and most were less than 8 inches in length. Good numbers of smallmouth bass were encountered. Keystone Lake appears to be home for numerous quality sized walleye, tiger muskellunge, and smallmouth bass. Additional sampling will be done in late May to evaluate both small and largemouth bass.

So I highly doubt PFBC spent the money to source "Splake" eggs.
