Very low if any fishing pressure. There are bass around but not much for any trout due to successive low water years and no stocking. Personal watercraft is launchable, but larger vessels are not recommended as there are no improved ramps accessible.

There is a hardpacked area near the dam, which can launch smaller vessels but you must take a left before going out to the dam parking lot, and hug the shore and avoid some rocks in the lake bed to access it.

Hyatt lake resort, store and restaurant are open. This is a great place to swing by and grab a bite to eat for mountain visitors.

The BLM campgrounds are open and can be reserved at Recreation.gov. 

There is a Hwy 66 and Hyatt Lake Rd webcam that may help you if you are planning a trip. Also, ODOT trip check is worth looking at
