Orange County's once premier private bass lake has died. Golden algae has devastated the fish population. Mass die offs happened earlier this year, halting trout plants. As a result Mission Viejo Lake recently began planting tilapia and catfish. Since neither Chul or I had ever caught a tilapia on a fly, we thought we'd give it a shot. What a waste. We have never seen the water in such a sorry state. It's quite a shame. All the fish we saw were died ones floating on the surface. One at the docks which was a tiny sunfish and later a 2 pound catfish. We were told the tilapia were holding deep. Without a fish finder and armed with only 5 weights with 150 and 220 grain heads it was pointless.
