Are you talking about the ODFW site out there on Buena Vista Road??? It has a locked gate and a dirt parking lot with an ODFW sign about a wilammette spillway?? Its a bit of a hike to the main pond from the road. If its the same one, i have fished out there a bunch of time. Some pretty good bass fishing out there. I have some people catch some hogs out of there! I was out there a week ago and the fishing was pretty good.
