The Ghosts of Lexington

There was an article in the Mercury News today about a ghost town re-emerging due to the falling waters of Lexington Reservoir. The reservoir has been drained to allow construction of new outlet pipes. This has caused the remnants of 2 former towns, old roads, and an old bridge to re-appear. The towns were Alma and Lexington. They were drowned when Lexington Reservoir was built in 1952. Hwy 17 also ran through here. This was a rare and possibly one-of-a-time opportunity to see this, so I went out to Lexington Reservoir County Park on Sunday 12/7/08 to see it. I carried a GPS receiver to record the GPS coordinates of some landmarks.

I parked at a small parking area on the side of northbound Hwy 17 just north of Bear Creek Road and south of the turnoff to Alma Bridge Road. It is across Hwy 17 from Black Road. There is an official park entrance (shown as "ENTER" on the map at the bottom of this page), service roads, and informal trails here. When the reservoir is full, it's a short walk to the shoreline. Now, you can hardly see the water.

Since I didn't know where the ruins were and did not have a map of the lake bottom, I didn't know where to go, so I improvised. I basically headed straignt for the lake across a long flat plain. I came to the side of a hill. Walking down the hill, someone left a memorial cross here. Ahead is a valley that was probably an old creekbed.

You can see a concrete channel in the old creekbed.

As you reach the bottom of the old creekbed, you can see the dried, cracked mud that was once the lake bottom. The bottom was firm today, but will probably not be once we get more rain. I do not recommend taking this route after it rains. Also, all those plants have burrs, which stick to your clothing.

Below, you can see the old bridge.

An old paved road, probably the remnants of old Hwy 17 can be seen going up the hill paralleling today's Hwy 17. Parts of the roadbed have been washed away. The current southern shoreline of the reservoir can be seen just ahead.

Here is one of the washed out sections of the road.

Here's another washed out section near the top of the old road.

The old road continues on through the woods ahead. From the map in the Mercury News article, it looks like it ends at Old Santa Cruz Highway.

Looking south on Lexington Reservoir, you can see pipeline that is probably being used as part of the dam project. That little trickle of water down the middle is technically Los Gatos Creek.

Zooming in, you can see the pipe snaking along the reservoir bottom. The trees on the opposite shore indicate the maximum level of the reservoir. Somewhere farther south, way back down along the reservoir bottom, is the site of the old town of Alma. I didn't go farther south. I turned around and went back north.

Heading back north on the old road, it comes to the usually submerged bridge.

The GPS coordinates for the bridge are N 37° 11.507 W 121° 59.369, shown as "BRIDGE" in the map at the bottom of this page. This is the upstream side at the mouth of the old creek.

The remaining water of the reservoir laps up to the downstream side of the bridge.

This shows the bridge was built in 1926.

The upstream side of the bridge is soft mud now. Deep footprints in the mud show that it is not advisable to try to cross the creekbed near the bridge.

A short distance north of the bridge are the foundations of an old building, possibly a house. This is at the site of the old town of Lexington The GPS coordinates for this foundation are N 37° 11.586 W 121° 59.359, shown as "HOUSE" in the map below.

This was a long, narrow room.

It looks like there was a small room on the side.

Looking south along the foundation.

The remains of a small out-building are here. The GPS coordinates for this structure are N 37° 11.611 W 121° 59.365

Continuing north along the old road.

As the road drops down, you can see foundations near the shore.

The foundations of a small square building built along the slope are here. The GPS coordinates for this foundation are N 37° 11.689 W 121° 59.352, shown as "ROOM" in the map below.

Closer to the shore are the foundations of another small room. The GPS coordinates for this foundation are N 37° 11.701 W 121° 59.318, shown as "BLDG" in the map below.

Looking north towards St. Joseph's Hill.

To north, across the lake, you can see what looks like the new intake structure for the dam.

Looking west at the foundation, you can see the some large boulders on the hill above the old road.

This looks like the base of a sign or lamppost. The GPS coordinates for this base are N 37° 11.744 W 121° 59.321, shown as "BASE" in the map below.

Looking at the base from a group of boulders N 37° 11.748 W 121° 59.339, which are shown as "BOULDERS" in the map below.

Near the end of the old road is a large concrete slab. The GPS coordinates for this slab are N 37° 11.782 W 121° 59.369, shown as "SLAB" in the map below.

This shows the road as it heads down towards the dam.

Another view of the slab, showing a ramp, indicating this slab may have been the floor of a garage.

Looking across the lake at the boat dock for Santa Clara University's rowing club.

The old road ends near the dam. To the left above is the Alma Bridge Road bridge over the dam's spillway.

Returning back to the parking lot, I followed along the old road for awhile. Looking back towards the dam, there is a steep dropoff along the side of this hill, which is usually underwater.

Looking back towards the east shore, showing this large cove, which is normally underwater. The hills in the background are part of Sierra Azul Open Space Preserve.

Close to Alma Bridge Road, you can see the high water line, just below the trees. There is a flat area, then a slope.

Looking towards the dam and intake structure.

There is a tunnel under Hwy 17, which emerges next to Black Road (shown as "TUNNEL" in the map below). It is big enough to walk through and high enough above the lake so that it  is not a water tunnel. Unfortunately, the west end was wet, so unless you don't mind risking getting your feet wet, it's best to wait until summer to take this. The parking area is just a little to the south of this tunnel.

I drove over the east shore of the lake. This is a view of the ruins from the Miller Point Picnic Area.

I drove back to the dam and parked near the St. Joseph's Hill trailhead. I walked across the dam towards the Los Gatos Creek Trail. This is a view from the dam, showing how low the water is.

This floating line usually marks the limits for boats before the spillway.

The detour for the Los Gatos Creek Trail goes along the spillway and under the Alma Bridge Road bridge.

Using coordinates downloaded from my GPS receiver and loaded into Magellan Mapsend, this shows the relative location of the structures above. The yellow line shows the route that I took. "ENTER" is the parking lot on the side of Hwy 17. "TUNNEL" is the tunnel under Hwy 17 to Black Road.  It is best to take the route from "ENTER" to "ROOM" to reach these ruins and not the southern route I took at the start to reach "BRIDGE"

This is a satellite photo of Lexington Reservoir as it usually looks, from Google Maps, showing the parking area along Hwy 17 and the location of the old bridge. The tunnel under the road is just north of the parking area.
