I used to fish Rock Lake while at WSU. Yes there are rattle snakes, we would run into them along the sunny side of the lake as early as April. There were many occasions where the wind would came out of nowhere. We used to sit out the wind or hug the shore line slowly to make it back. We decided it was not worth putting ourselves into that situation, and would walk the creek and fish the shoreline around the lake if we could grt permission. We would catch browns at night with a slip float and glow jig tipped with roe. Rainbows with power bait. We used to throw a lot of spoons (krocodile) and get the aggressive trout. Bass when the water would warm up in the late spring along the edges. We would catch the occasional crappie and catfish also. Carp fishing was popular with corn near the launch at the outlet wih some fishermen. Good memories!!
