Lake Owyhee is about 26 miles south-southwest of Adrian and is paved all the way. There are no guard rails on the road along side the lake, so don't flip out.
The dam was the prototype for the massive Hoover Dam in Nevada/Arizona. The Owyhee dam is impressive. The lake has 2 state parks and 4 boat launch ramps. If you like primitive camping, load up your gear and hop in the boat and find a secluded cove. There are a lot of them. It takes a long time to get to the end of the lake where the Owyhee river flows in, but it is worth the trip. If you have a fishing license, drop your lure in and catch some crappie, bass or trout or maybe an old boot. You are likely to see a lot of wildlife out there, as well. I have personally witnessed mule deer (does) swimming across a narrow spot in the lake and have seen numerous big horn sheep as well. The lake has always been a great place for skiing (behind a boat or jet ski), swimming, picnicking and camping. Back in the 80's the resort was a happening place doing excellent business. Back in the late 60's my great-grandparents owned the resort. The last time I was there, the place was boarded up and the motel was torn down. It is more like a park now.
