Hey Rob.
I have been on some windy days at clear Lake But, the only day I was truely afraid was one day on Don Pedro years ago... The waves were moving from Rogers creek up into the mouth of Big Creek and the mouth of middle bay. The wind that day was already bad enough in the morning. I told my buddy this is the kind of days they may close the lake if we are going to do any fishing at all lets go and see how it is. We went out from Blue oaks and fished the back of Graveyard, It was the only area blocked by the wind of any size. We started catching fish and having a good time as the wind got far......worse. We started talking about how bad it was and thought we would wait it out and see if it would calm down. NOPE, it got even worse the waves looked like Big Ocean waves crashing on the opposite side of the lake. I have fished many break waters so I know what that looks like. The wind was so loud through the mountain trees, I have never heard it that way before. The wind at times would come over the mountain and punch down on the water and create spray that would then get picked up by the wind and looked like a water sprayed whirl wind. We wanted off this lake at this point. So we tried to make it back, It took us Over 1 hour to get from Graveyard to Blue oaks. That run takes maybe 4 Min on a normal day. We were going backwards as we crested the waves, If I went any faster we would spear the next wave. There was no little white caps just giant white lines. My boat is only 17' There was that much room plus in-between waves. It almost felt like we were going to go over backwards at times. It was not like anything to this day I have ever seen. When we made it back, Thank GOD, The ranger said How did you guys make it? We said we crawled. They did close the lake that day. We were told there was one more still out there. Mc Clure closed that day also. The ranger said one guy washed up at Mc Clure that day too. I will say at that time I was not thinking of taking a pic of the waves. It would have been cool. I don't wish that experience upon anyone.
Don.
