The DFG's fish planting program is still not settled. While waters like the Kern River are back to being stocked many waters will remain or become no stock waters. It seems one of the strong factors for making decisions on stock or no-stock is the waters contact with endangered Steelhead. This means: "Lake Cachuma, Lake Casitas, Lake Piru, Castaic Lagoon, Piru Creek, Bouquet Canyon Creek and all the forks of the San Gabriel River drain directly into historic steelhead drainages and will not be planted in the near future."  
 
Other factors including the effect of planted trout on native species other than trout or steelhead are still being evaluated in some areas and may result in no stocking status of other waters including some urban lakes.  
 
One of the possibilities that will be proposed by the DFG will be the use of Triploid Trout for stocking sensitive waters. While Triploid fish have been altered genetically by applying high pressure or heat to the eggs rendering the resultant hatched fish sterile, most scientists will not claim this to be 100% effective. Triploid trout generally grow large and fat and are commonly stocked in the pay to fish lakes. The State of California classifies these fish differently form normal trout in State records.
