I found this lovely walk while out doing a little caching, it's a man-made Drainage/Irrigation Culvert that feeds the reservoir, it goes on for many miles. You may see lots of wildlife around you and It will be very quiet. After we left the reservoir parking spot we saw nobody for three hours enjoy your dander, the culvert is a fabulous place to play Pooh Sticks, why not take some ducks with you and race them down the channel.
