Park is in pretty good shape, although it appears that the state park system is low on funding and resources, as some facilities are closed and maintenance is needed in certain areas. The park is located within a large watershed/basin, so seasonal rains can have an impact on the area at large. With that being said, being at the heart of this basin allows for many water borne recreational activities. Boating, kayaking/canoeing, fishing, observation of diverse flora and fauna. Besides having access to a boat launch on site, there are several boat launches with access to other water bodies within a few miles of the park.
Have been to the park a few times over the last 20 years. Have stayed in the old cabins a few times and have also made day visits to the park. My most recent visit was my first visit as an RVer. I stayed at campsite 40, which has water access, with a dock. This was convenient for launching kayaks. I found the rv pad to be on the narrow side of things and the utilities (water/electric) were located in an odd location. I forgot my electric power extension cord and had to pull up on the pad, in order to reach the electric service. I had to run the water hose under the rv and across the outdoor walking/living area. I'm not sure if these sites were poorly designed or if intended for drive in setup. The sites on interior or opposite side of road seemed to be setup with utilities on the "correct" side. Also, we could not extend the canopy, due to a tree being in the way. Sorry, I do not have pictures of the site, but I see someone else has posted pics of site 40.
Mosquitos were swarming post rain shower, which occurred each day of the trip. So, cool weather camping may be preferable, or perhaps when water is not standing in the low lying areas (the whole park is essentially a low area).
