I can't even see it in the picture. You can try to boof it loose. Most likely you will just have to wait for the river to come down. IF it is close enought to the bank you could use a stick or pole with carbiner and rope attached to try and snag a grab loop, that doesn't look to be the case though. If you are going to be working on it with ropes make sure you have someone upstream notifying downstream kayakers. I will boof it.
