Current Flows have been all over the map. Currently they are 251 CFS. Bridgeport reservoir is full and I would imagine upper and lower Twin lakes are as well. Irrigation season is right around the corner and the flows could go up any time now. If you are want to fish the East Walker you should go soon and check the flows before you get in the car.
The East Walker is fishable right now but it could change anytime. Be careful wading there are not too many spots that you can cross with the current flows. Nymphing with a Stonefly and a smaller dropper like a Baetis or a Midge along the edges and out of the main current is a pretty good way to fish the East Walker when the flows are high. Streamers can also be effective.
