With new pontoon in tow I headed out to camp at Potholes State Park and fish the Seep Lakes over the weekend of April 9th-11th. I had fished a few of the lakes two years ago around the same time of year. WDFW describes the lakes as “within the ‘channeled scablands’ of Eastern Washington, that were created by ice age floods during the Pleistocene Epoch.” In less poetic but more descriptive text, they are a group of over 50 lakes that were formed when the Potholes Reservoir was formed and the water starting moving through the water table and arising from the desert south-east of the reservoir.
Not a lot has been written in the way of consistent fishing reports from the lakes. What is known that various of the lakes have been stocked a few times over the last ten years, with some holding big trout and some holding none. It is also known that some of the lakes were poisoned at one point or another over the last five years in order to clear out carp that had found their way in via the irrigation channels connected to the Columbia. It was hard for me to get any clear timeline of what had been poisoned and when. This made it hard to be confident in the only two lakes that we chose to fish during our time there. There was barely any surface activity and depths were scratched out for us via Scott’s sonar, which were helpful to know in colored up water.
We fished Corral on Saturday from mid-morning to after lunchtime. It’s a longer lake with pocketed channels and typical rocky points and walls which is where we concentrated our efforts. I fished a spinner that Scott had made with a black snowman body and wide, heavy gold Colorado blade. Scott found me a drop off on the sonar and marked some fish. I was having oar issues and stubbornly left my motor at home so that I could experience the ride of my new watercraft. I dropped anchor and cast into the deep, let the spinner sink for about 10-15 seconds and slowly reeled. My thought was that the spinner would be reeled in at an angle matching the incline of the bottom towards where I was anchored. I was thinking too much. There was a fair amount of snags to be had and the water clarity was a bit rough. Regardless, I hooked a nice fish close to 9am and then nothing the rest of the day.
After a siesta we stacked the pontoons on my truck and headed to Blythe Lake, which is just a hop over the hill from Corral. Blythe is smaller and more manageable in a pontoon or float tube, had some great structure and scenery, but was a soupy mess from aquatic plants coloring up the water. About an hour before sunset there was an intense gnat hatch along with some emerging insects of some sort that brought on our first real surface activity of the day. What I was convinced was the same fish made it’s way from the boat launch south across the lake, periodically coming up for a thrashing gulp. We got zero bites but were somehow satisfied that at least we knew they were there. The lake had not been poisoned.
Below is a map of the area. The first lake is a few minutes away from Potholes. The Clark-Skamania Flyfishers were a great resource and I would encourage taking at least a couple days and buddies to try and hit as many lakes as you can. I’d like to take a trip there in the fall with some time set aside for hiking in to some of the lakes only accessible by foot.
