HARFORD SPRINGS RESERVE: 3/10/17 (Gavilan Hills, Riverside County, CA)

Harford Springs Reserve is a 325 acre Riverside County Park that sits on a plateau at around 2,000' elevation in the Gavilan Hills area 2 miles south of Cajalco Road. Oaks, California Junipers, a nice variety of spring wildflowers and the absence of throngs of visitors makes this place a true hidden gem. One of the takeaways from this trip (other than the inherent beauty of this locale) is the fact that you can't always trust WAZE. Yes, Waze - that GPS-based navigation app that so many of us love to use when stuck in traffic. I'd say it's about 90% accurate most of the time, but in this case we ended up on the south part of the reserve at an entry point that was gated because it happened to be private property. So Waze took us from I-15N to Cajalco Road east, then south on Lake Mathews Drive, north on Gavilan Road, north on Idaleona Road, and finally north on Piedras Road where we dead ended at the gate. Undeterred or perhaps clueless at this point, we continued up Piedras Road and turned left at the next intersection on Panamint Road where we parked across a farmstead. The lady of the manor was very friendly, surrounded by her large pack of barking and jumping doggies and enthusiastic children, and said that we could hike into the preserve from across the way, and so we did. The trails here are dog, horse, bicycle, and ATV friendly, but we didn't encounter any of the above on this trek. I wasn't able to find an official website for this RivCo park, but here's one from a hiker who has traversed these parts: http://californiathroughmylens.com/harford-springs-reserve.  On our return back to Cajalco Road, we discovered that the "official" entry to the park was only a short distance south of Cajalco Road off Gavilan Road, so duly trip-noted.

LAKE MATHEWS (Riverside County, CA): March 10, 2107


On our way to Harford Springs Reserve in the Gavilan Hills area off Cajalco Road in Riverside County, we passed by Lake Mathews, which looked beautifully calm and serene in the distance. This reservoir, fed by inflows from the Colorado River Aqueduct and surrounded by several thousand acres of protected land, has been closed to public access for decades.



From Wiki: https://en.wikipedia.org/wiki/Lake_Mathews 

Lake Mathews is a large reservoir in Riverside County, California, located in the Cajalco Canyon in the foothills of the Temescal Mountains. It is the western terminus for the Colorado River Aqueduct that provides much of the water used by the cities and water districts of the Metropolitan Water District of Southern California. The reservoir is fenced and closed to all public access. The lake is near the Riverside community of Lake Hills, and is skirted by Cajalco Road on the south, El Sobrante Road on the north and east, and La Sierra Avenue on the west. La Sierra Avenue traverses the top of the west dike. These roads are often used by commuters as a shortcut between Interstate 15 and Interstate 215 or California 91.
The reservoir was constructed by building a large earthfill dam across the northern side of the basin. Two smaller dams, called dikes, were built during the 1961 expansion to increase the lake's capacity.

History[edit]

Originally named the Cajalco Reservoir, the reservoir is now named after W.B. Mathews, an attorney who was a key architect of the MWD and its business relationships with member water agencies. Construction on the reservoir began in 1933, at the same time the aqueduct was being built across the desert. The reservoir site had previously been occupied chiefly by carob orchards and tin mines. Lawrence Holmes, Sr., who owned 1,100 acres in the future reservoir basin, lost his property to eminent domain in a lengthy court battle. The dam across Cajalco Canyon and its intake structure were completed in 1939. The first water arrived from the Colorado River in February 1940, and water deliveries began in 1941. In 1961, the reservoir’s capacity was nearly doubled to its current capacity of 182,000 acre-feet.
In the mid-2000s, a large project was undertaken to rehabilitate the old outlet tower and to construct a new tower as an alternate. The MWD was concerned about the tower’s susceptibility to earthquakes, and age had rendered many of the tower’s massive valves unusable. To allow for construction without impacting the water supply, a cofferdam was constructed. Massive concrete tunnels were built to connect the new tower to the existing waterworks.

Lake Mathews Ecological Reserve[edit]

Lake Mathews is surrounded by approximately 4,000 acres of protected land. In 1982, this land was declared a State ecological reserve. In the early 1990s, an additional 9,000 acres was added to the reserve after the discovery of the endangered Stephens kangaroo rat (Dipodomys stephensi) in the area. The area is now called the Lake Mathews Estelle Mountain Reserve.
The Lake Mathews area is an important bird resting and feeding site, particularly in the winter months. In addition to a variety of ducks, double-crested cormorants (Phalacrocorax auritus), Western grebe (Aechmophorus occidentalis), eared grebe (Podiceps caspicus), golden eagles (Aquila chrysaetos), and bald eagles (Haliaeatus leucocephalus), are present during the winter.

Controversy over recreational use[edit]

Since its dedication in 1940, the reservoir has been fenced off and closed to public access, supposedly to preserve water quality. The MWD has always been concerned about water quality and prohibits body contact sports like swimming in its other nearby reservoirs that are open for recreation, Lake Skinner and Diamond Valley Lake. Mathews is of greatest importance as its outlet feeds directly into pipelines that connect to member water agencies serving 8.4 million people. Proponents of recreation assert that recreation does not and cannot cause significant impairment to water quality and dispute MWD claims.
Another concern raised by opponents is preservation of the coastal sage scrub biome that has developed over time on the protected land around the lake.
During its existence, a number of attempts have been made to gain access to the lake for various purposes, but none have been granted. One of the most interesting was a 1952 request for a movie shoot at the lake. The scene from the 1953 movie Fair Wind to Java would have featured, among other things, a smoke-belching volcano constructed on one of the lake’s islands. After their idea was rejected by the MWD Board, the movie’s producers reportedly constructed a lagoon and volcano on a studio backlot.
In 1960, the Riverside County Board of Supervisors mounted an unsuccessful campaign to open the lake for recreational purposes. The board generated a resolution citing a “pressing and definite need” for recreational facilities in Southern California.
California Assemblyman Kevin Jeffries, on February 14, 2012, introduced legislation, AB 1686, which would have opened the lake for limited recreation similar to that available at other MWD reservoirs or, at the very least, have allowed for low-impact hiking in the Ecological Reserve. However, Jeffries withdrew the bill on March 20, 2012 after research determined that “virtually bulletproof” agreements prohibiting public access exist between the MWD and other entities interested in maintaining the status quo, and going forward with the bill would have likely resulted in prolonged and expensive legal battles.

CORONA LAKE (Corona, Riverside County, CA)

Corona Lake is a privately stocked lake east of I-15 off Temescal Canyon Road and used to be a popular fishing spot (fishing license not required) for bass, rainbow trout, tilapia, catfish, bluegill and crappie. They have a large sign visible off the freeway saying something along the lines of "Largest Trout in California Caught Here" (I believe the record was 24.5 lbs.). In 2016, we noticed that the water in the lake  started evaporating over the course of the year until it looked more like a pond. Clearly, the the water in the lake was receding, not being replenished, and no longer in operation - surely because of California's ongoing drought. But then we had a wetter-than-expected winter this past season, so the lake is once again filled to the brim. 

The latest report from http://www.fishinglakes.com/locations/corona-lake/  indicates that, despite the auspicious rains, the lake is still closed to fishing. I imagine the lake has to be great for birding so will keep checking in on its status.
