Location

The Canyon del Rey Watershed is located entirely in Monterey County within California's Central Coast Region. The watershed is approximately 16.8 square miles and contains portions of the cities of Monterey, Del Rey Oaks, and Seaside[1]. The Canyon del Rey Watershed drains into Arroyo Del Rey a perennial stream that begins in the eastern portion of the Canyon del Rey watershed near Laguna Seca Race Track, and flows west terminating into the Monterey Bay.

Watershed Components

Arroyo del Rey (Canyon del Rey Creek)

Arroyo del Rey is the main creek of the Canyon del Rey Watershed. Arroyo del Rey has also been called Canyon del Rey creek in local studies conducted for MPWMD. The name Arroyo del Rey is often used by the USGS, city of Del Rey Oaks, and past Central Coast Watershed Studies (CCoWS) projects. The creek begins in the east along Highway 68 near the Laguna Seca Race Track. It flows westerly next to Highway 68 until it reaches the Ryan Ranch Business Park in Monterey[1]. The creek then follows Highway 218 into the city of Del Rey Oaks. Arroyo del Rey runs through recreational areas including Frog Pond Wetland Preserve and Del Rey Oaks Park, then going through the community of Seaside where it creates both Laguna Grande Lake in Laguna Grande Regional Park, and Roberts Lake [2]. The outlet of Arroyo del Rey is located within Monterey State Beach[3].

Lakes and Preserves

Subbasins

South Boundary

The northern portion of the Canyon del Rey Watershed known as the South Boundary Sub-basin contains a large amount of sandy soils that offers little runoff into Arroyo del Rey. The underlying geology consists of Aromas Sandstone and Paso Robles Formation [4]. The South Boundary Tributary is an ephemeral stream located in the northern portion of the Canyon del Rey Watershed which confluences with Arroyo del Rey near Frog Pond Wetland Preserve. Very rarely does the South Boundary Tributary contain any flow.

Upper

The southern portion of the Canyon del Rey Watershed known as the Upper Sub-basin contains an underlying geology of Monterey Shale and Santa Margarita Sand Stone. The sub-basin included portions of Ryan Ranch Business Park, Pasadera Golf Course, and Laguna Seca Race Track. The Upper Sub-basin contributes the most ammount of runoff to Arroyo del Rey. The runoff from both golf course and residential irrigation contribute and help sustain a base flow for Arroyo del Rey in the summer time [4]..

Lower

The western portion of the Canyon del Rey Watershed is known as the Lower Sub-basin. It contains allot of urbanization with both residential and commercial development from the cities of Del Rey Oaks, Monterey, and Seaside. The lower Sub-basin includes both Laguna Grande Regional Park and Roberts Lake

Canyon del Rey Watershed Joint Powers Agency

The Canyon del Rey Watershed Joint Powers Agency (JPA) was created in 1980. [5] There is currently no record of any CDR JPA meetings since its creation in 1980. When first being organized, seven major parties were considered for being members of the agreement. Of these, Fort Ord agreed to cooperate with the agency's efforts but can not join the agency. Fort Ord is no longer an active military base and reuse planning associate with this land is conducted by the Fort Ord Reuse Authority (FORA). Understanding FORA and United States Army involvement in the CDR JPA is uncertain and should be a topic of further research. Additionally, the Monterey Peninsula Airport District declined to join the agency.[5]

Purpose

To sustain and improve the water quality of Laguna Grande and Roberts Lake, by coordinating future development and maintance of the Canyon del Rey Watershed [5].

Public Agencies Involved in the Canyon del Rey Watershed JPA

Responsibilities of Agencies

  • Create laws and best management strategies that help reduce the amount of surface runoff and erosion into the Canyon del Rey Watershed
  • Find outside funding to lower local expenditures for improvements.
  • Broker the distribution of cost for various restoration projects. [5]

Monitoring Sites

Flow Gages

California Central Coast Gage Locations page has more information on these gages.

Precipitation Gages

  • (Active) Laguna Seca Gage (Recorded at Hourly Intervals) managed by CIMIS
  • (Active) KCAMONTE 21 (Recorded at 15 min Intervals) data distributed through Weather Underground
  • (Active) KCAMONTE 67 (Recorded at 15 min Intervals) data distributed through Weather Underground
