When you say," north end of reservoir", I'm assuming the potholes? Correct? I'm going to assume, it is. When it comes to the potholes, until the water level comes up, google earth, GPS, and ONX will be your friend. The reason is when the water is low, like this time of year. The pothole becomes a maze of epic size. What makes it so bad is that, the geography is as flat as a pancake, not many high dunes, to get your bearings. And even if you know the direction to go, can you find a channel to get you there. I added the screen shot, to show what I'm talking about. Much better images on google earth. Learn to use the historical images option, in GE. It is worth the time. As far as the wasteways go, I run my john boat and outboard in the wasteway frequently, no problem. Again google earth is great for studying water channels and wasteways. I don't feel I'm giving away any trade secrets, I'm sure some will disagree. But a old timer once told me, "There are no more secrets in the basin, just people who hunt harder than others". As a general rule, I think he is correct. Would like to show you around, but my truck took a dump this morning, on my way to the basin for some scouting. It's going to be in the shop awhile. Good Luck
