A new acquisition doesn't show up in the Rec Compass until the WMA has been designated by a Commissioner's Designation Order. Until that point, the land may be owned by the state and open to hunting, etc., but technically it's not a WMA. Typically those orders are only issued once or twice a year, not on a rolling basis. Add to that the long, drawn-out process for real estate transactions, and a parcel can take 2-3 years from the time a partner buys it (such as PF or DU) and when it actually shows up in a public mapping resource. Occasionally there are other issues, but that explains 90% of the lag.
