Mystery And History

Arguably one of the crown jewels in the Redding area’s vast system of trails, a major portion of the Princess Ditch Trail follows the course of the historic Princess Water Ditch. How did the ditch come by its regal name? When and why was it constructed? Where did the ditch obtain its water? And why does the water ditch abruptly stop high above the very deep and wide Clear Creek Canyon? Answers to these mysteries are found in a written history of the Princess Water Ditch which was researched and compiled by the late archaeologist Barbara Woodrum for the Bureau Of Land Management.

The Princess Water Ditch (constructed between the summer of 1896 and January, 1897) takes its name from the Princess Hydraulic Mining Company which was established in Leadville, Colorado, in 1896. The ditch supplied water to giant monitors (water cannons) which were used to wash away large areas of gravel-laden sediments where gold deposits were often found. Water for the ditch most likely was drawn from Paige Boulder Creek near today’s N.E.E.D. Camp-Whiskeytown Environmental School. The ditch’s water flowed in a southerly direction high on the western flanks of Clear Creek Canyon for approximately one mile. At this point, the water entered a pipe which had a length of 2,000 feet and a beginning diameter of twenty-four inches. The pipe plunged down the western side of the canyon, crossed above Clear Creek, and ascended the eastern side of the canyon while also passing over the earlier-built Clear Creek Water Ditch. Now high above Clear Creek, the pipe (which narrowed to twenty-two inches in diameter toward its end) deposited its water into the Princess Water Ditch which now flowed on the eastern flanks of Clear Creek Canyon! Twenty-five men were paid ninety cents each ($25.33 in 2017 dollars) a day to construct the ditch which had a length of fourteen miles. Costs associated with this project included $14,000 ($394,000 in 2017 dollars) for the construction of the water ditch and $5,000 ($141,000 in 2017 dollars) to complete work on the pipe. The total cost of the project, including equipment, dams, sluice boxes, shops and other buildings, was $30,000 ($844,000 in 2017 dollars).

Trail Description

Virtually all of the first 3 ½ miles of the Princess Ditch Trail runs above the actual Princess Water Ditch grade. Starting from the parking area at the Oak Knoll Trailhead, the trail is generally oriented in a south to north direction and somewhat parallels Mule Town Road (which is always below the trail). The trail follows the contours of several canyons along its length and enters the Whiskeytown National Recreation Area at approximately the 6 ½ mile mark. Numerous bridges and culverts help to keep trail users dry, but long sections of the trail may be inundated with several inches of water during the rainy season. Beware of ticks and poison oak. Watch for other trail users, and carry plenty of water!

From the Oak Knoll Trailhead, cross Mule Town Road and ascend about a quarter mile to the trail sign which shows Princess Ditch Trail to the left and Mule Ridge Trail to the right. Turn left and travel about two tenths of a mile in the actual Princess Water Ditch Grade before leaving the ditch to travel mostly upward for approximately one mile where you will reach the highest elevation of the trail. On this initial climb there are great views to the west. Below, you can see the bridge which spans Clear Creek, and farther west the Bald Hills are backdropped by mountains of the Coastal Range.

Now the trail mostly descends for the next three-quarters of a mile crossing two private driveways and two streams. Then over the next mile the trail moves up and down crossing two more streams before arriving at the junction with Cosmos Way – a very steep trail which connects to Mule Ridge Trail. Save Cosmos Way for another day!

Ahead, the trail forks. For this trail description, I chose to travel the lower fork. Don’t be fooled by the closed trail which heads directly downhill and is clearly signed. Descend steeply for approximately a quarter mile before re-entering the old Princess Water Ditch Grade. This is where the trail can be very wet for long stretches ahead during the wet season.

A little more than a half mile ahead, the upper fork (the one I didn’t take back at Cosmos Way) intersects the trail. Proceed straight ahead. Over the next 3 ¾ miles the trail mostly stays in the ditch grade, crossing several creeks by way of bridges.

Should you run out of time or energy, there are two points on the trail where you can exit and descend to Mule Town Road to follow its more direct route back to Oak Knoll Trailhead: One is at approximately five miles into the ride where the trail from the Stoney Gulch Trailhead intersects, the other is about 6 ½ miles into the ride where another trail comes up from Mule Town Road.

At approximately the eight mile mark, you come to the spot where a 2,000 foot-long pipe carried water from the other side of the canyon to this side. A very nice view of Shasta Bally Mountain can be had here. I was very fortunate to be guided to a section of the canyon far below by longtime resident and history buff Al Carter. A large rock and concrete pier that supported the pipe as it crossed Clear Creek still exists, along with remnants of thick steel cable that were used to keep the pipe in place.

The trail now curves right and moves upward as it leaves the old ditch grade. Six tenths of a mile ahead the Princess Ditch Trail ends where it intersects the Salt Loop Trail.

    This is the exact kind of article that needs to be promoted to bring tourism into Shasta County.  Here in Wyoming and especially in Colorado, areas with no winter access, lure bikers and their money for one day trips.  The Denver Post recently stated outdoor recreation and tourism bring in $39 billion a year.  With all the non-paved roads and trails outside Redding the opportunity for biking needs to be promoted more.

    Mayor Weaver’s recent Mountain Bike Challenge included this section of trail and was a delight to bike this past spring. We local folks are very fortunate to have the many miles of excellent hiking/biking trails in such close proximity to town. Thanks to all who worked so hard to create them.

    Great write up and pictures Chris!!

    Great article, I learned a lot about this water ditch, different than the ones built in the 1860’s.  Hopefully this can be followed up with another article about where the water ditch ends.  Did this one go to Mary Lake?

    • Marilyn Carter says:

      Ditch was for the Princess Hydraulic Mine located off  Diggins Way, between Placer and Clear Creek Road.

    Nice article. I ride my bike out there quite a bit and always wondered about the history of the ditch.

    From what I’ve read, hydraulic mining was outlawed in CA in 1884, so this must have been for water supply only, and not washing away hillsides (actual hydraulic mining).  Or maybe there was some loophole or the law poorly enforced?
