Snaggedagain,
Blacknose crappie are not common in Kansas waters. Seems like most of the blacknose reports I hear about come from Hillsdale. KDWPT does not and has not stocked blacknose crappie. However, private fish farms do market blacknose crappie which private pondowners can buy and stock in to private waters. During heavy rainfall events fish can be flushed from the private ponds and find their way to larger waters such as Hillsdale Reservoir.
Here's a thread from a few years back where blacknose crappie were discussed. http://www.crappie.com/crappie/ask-the-biologist/192611-black-nosed-crappie/
