You can get permits for camping and your cars at one of the gates.
If the marina is open? Otherwise nearby Emerald has a convenience store at S.W.84 & Hwy 6 that sells park & fish licences.
Do all lakes in Nebraska make you get a vehicle permit as well as camping rate? Kansas doesnt require vehicle fee if you paid for camping...
The state park permit and camping fees are available at the main park station office. $35. For permits for 2019. $25. Per night for camper with power hookups 30 or 50 amp. Tents and no power areas are cheaper. Good times a head, be safe and watch weather co continuously.
