About
St. Mary Lower Campground offers shaded, powered sites suited for both tents and RVs. Some sites sit right along the water, providing peaceful views and easy shoreline access. The attached Lower Day Use Area provides a playground, picnic shelter, and basketball halfcourt. This campground is a hotspot for birdlife; if you’re lucky enough you might catch a glimpse of the great blue heron wading through the waters!
Reservations can be made 90 days in advance of arrival date.
When camping in a powered site:
Use 1-2 electrical appliances maximum at the same time. When campers lose power, its usually it is because too much electricity is being used at once.
Do not use adapters to draw power from a 15 amp for an RV with a 30 amp plug.
Have a backup plan. Use other methods to cook, stay cool and keep entertained.
Remember, conserving electricity and timing when you use your electricity in a campsite will ensure you can stay powered. Get more information about using power sites.
Water: Please bring your own water. Water is not available on site.
