High water level does not usually mean no fishing. Water clarity is the key. If the river first floods due to heavy rain, the water is usually muddy with no visibility due to ground level run off. It is also full of trees branches and leaves. But when rain stops, and water comes from underground springs or seepage, or from slow snow melt, then the water will not be saturated with solids, and water clarity will increase even if the hydrometer shows the same water level as a rising fresh flood. You probably want to give the local tackle store a call before your trip to be safe. I called Fred's Tackle quite often during the steelhead season right before I started the car to see if water visibility is worth the trip. Of course I am a late bird and my call is done after they open shop in the morning. For early birds, you may want to call them the day before, before they close shop and pray that no overnight rain will spoil your fun. Other tackle shops can also help if they have most current reports from fishermen. Of course, there are unselfish FWR members like Chris who is tirelessly helpfull to report on river condition all the time.
