Volunteer Guidelines for Safely Removing Water Lettuce Version 2, Oct. 15, 2020

The Sepulveda Basin Wildlife Lake has become infested with an invasive plant called Water Lettuce. Unless controlled it can take over the Lake and hurt the fish and birds that depend on the aquatic plants and plankton there. Small patches were noticed in early September and it has spread at an alarming rate. While it is unlikely that it can be totally eradicated, it can be kept in check.

Removing the Water Lettuce from the Wildlife Lake before it rapidly spreads further is essential. Due to the corona virus a large event cannot be held. We need efforts by individuals and households to remove the Water Lettice. Masks must be worn when you are near others.

SAFETY:

· Observe social distancing and wear a mask.

· Be cautious for yourself and others when you use tools.

· Watch for slippery mud, plants with sharp ends and thorns, and roots to trip you.

· Be alert for your safety and your family’s safety. We can provide little if any supervision because of COVID.

· Your safety is your own responsibility and at your own risk.

HOW TO REMOVE WATER LETTUCE:

· Wear rugged clothing and boots or shoes.

· Bring a leaf rake or old pool net; large trash bags; drinking water; and optionally gloves;. (On weekend mornings there may be trash bags and a few rakes and nets available to borrow at the amphitheater.)

· Walk to the Wildlife Lake with your equipment and find a location where you can stand next to the water near the Water Lettuce. It moves with winds, so it may not be near all land areas.

o Do not enter the water.

o Do not trample plants.

· Rake Water Lettuce toward the shore. Scoop it up.

· Drain the Water Lettuce and place it in a large trash bag.

o Leave the plants whole, including their roots, the fuzzy stuff. Do not cut them. They can regrow from pieces left behind.

o Pick up and bag what you drop. Small WL plants will grow if they get back in the water.

· When the bag is full, take it to the edge of the main path. Take care you don’t block the path.

· If you are not too exhausted, repeat, filling another bag.

· Remove any green stuff from your boots/shoes to avoid spreading Water Lettuce to the LA River or other body of water when you are finished.

· A video with information for you is at https://youtu.be/qatC_7IstMQ.

· Share your effort by posting photos on social media. Link your Instagram postings to @sfvaudubon. Use the hashtag #InvasiveWaterLettuceChallenge to get them on CA State Senator Henry Stern’s social media.

June 8, 2020 - LOS ANGELES (CBSLA) – A four-acre brush fire broke out in the Sepulveda Basin early Friday morning. The blaze was reported at about 2 a.m. in the 6000 block of North Woodley Avenue in the Van Nuys area. The fire burned through heavy brush, spread by 20 mile per hour winds, the Los Angeles Fire Department reports. Water-dropping helicopters assisted ground crews who were also using heavy machinery to clear debris. All flames were extinguished by 5 a.m. and the fire was contained. Crews were continuing to mop up hot spots and cut lines around the burn area. There were no injuries or damage to structures. The Sepulveda Basin includes the Balboa Golf Course, the Japanese Garden, Anthony C. Benson Park and the Sepulveda Basin Wildlife Reserve. There was no word on a cause. The area often sees several homeless encampments. Most of L.A. County is under a red flag warning through Monday night due to gusty winds and low humidity. Photo below (c) CBSLA

The Sepulveda Basin Wildlife Reserve has been selected as the Winner for the 2020 Best of Lake Balboa Awards in the category of Wildlife Refuge. The Lake Balboa Award Program was created to honor and generate public recognition of the achievements and positive contributions of businesses and organizations in and around Lake Balboa. Our mission is to raise the profile of exemplary companies and entrepreneurs among the press, the business community, and the general public.

Change to Beginning Birds-and-Nature Walks at the Sepulveda Basin Wildlife Reserve:
Now Available for Groups by Reservation Only

To better match community interest, San Fernando Valley Audubon’s Birds-and-Nature Walks for families and beginners are changing format. They had been offered on second Saturday mornings October through March, as well as by reservation for groups. They are NOW available ONLY BY RESERVATION for groups. Reservations will be available for flexible days and times, including school mornings, weekend mornings, and after school. For the most part we will avoid scheduling walks in the summer months. Groups should be a minimum of 10–12 people. Partcipants will stroll through the lovely Sepulveda Basin Wildlife Reserve with a guide, enjoying its trails and wildlife lake. Many kinds of birds are found there, along with lizards, cottontail rabbits, butterflies, fish and more. Partcipants will learn about the plants and birds and see them up close and discover why this is such a special place. We have binoculars to loan or you can use your own. These walks are for groups such as school classes not eligible for our SBEEP program, scouting and other youth groups, community centers, religious centers, environmental groups, and clubs. For reservations contact Muriel Kotin at (310) 457-5796 or muriel.kotin@sfvaudubon.org. For information only, contact Diana Keeney at (818) 998-3216.

	In March of 1981, a revised Master Plan for the area was adopted. At the time, of the 2,150 acres in the Sepulveda Basin, approximately 1,060 acres were committed to recreational uses. The updated Master Plan designated an additional 540 acres for future recreational uses. Included in the plan are provisions for the commitment of approximately 220 acres of land to informal park space, 120 acres for development of a recreational lake, 108 acres for a wildlife management area, and 60 acres for an “arts park” that has been subsequently redesignated for a “sports complex” (the area west of Balboa Blvd. just north of the Los Angeles River.

	The Master Plan also tried to minimize adverse environmental effects and recommended “designing reaches of newly-formed lakes and ponds to emulate existing wetland conditions on the site and by replanting existing riparian plant species” and to “accompany new park developments with the introduction of native plant species to create new habitats in the basin.”

	In 1979 the Corp of Engineers developed the first area of the Wildlife Reserve (formerly called the South Reserve), an approximate 48 acre parcel located south of Burbank Blvd and bordered by the Los Angeles River and the Sepulveda Dam on the east and south. A “pothole” pond (fed with piped-in fresh water) was created, and vegetation representing coastal sage scrub and riparian woodlands were planted. This area was drastically altered in December 2012 and as of January 2013 there were ongoing negotiations between environmental groups and the Army Corps of Engineers (see section above below upcoming events).

	The approximate 60-acre North Reserve (north of Burbank Blvd., east of Haskell Creek, west of the Dam) was developed in 1988, featuring an 11-acre lake with an island and wildlife viewing stations. Various revegetation projects have been undertaken since then.

			About the Sepulveda Flood Control Basin
	Sepulveda Basin, 1953 (photo courtesy of Gus Harris)		All property within the Sepulveda Flood Control Basin is owned by the Los Angeles District Corps of Engineers, but more than 80% of the land is leased out for recreational and agricultural uses. Sepulveda Dam, completed in 1941, is a dry-land reservoir, with the purpose of controlling runoff from nearby San Gabriel, Santa Monica, and Santa Susana Mountains. Besides the Encino and Balboa golf courses, the Balboa Sports Complex, and the model airplane field, most of the Basin was devoted to agriculture (corn and then sod farms). In the mid-1960’s, Burbank Blvd. was extended across the Basin. In the 1970’s the City of Los Angeles Bureau of Sanitation built the Donald Tillman Water Reclamation Plant within the Basin (over the objections of the Corp of Engineers).

	In 1991 the Tillman Water Reclamation Plant Flood Protection Project was finalized, and subsequently a berm was built around the Water Reclamation Plant to protect it from flooding, compensating excavation was performed in various places, and the outflow from the Water Reclamation Plant was rerouted under the dam so the outflow was outside (to the south) of the Dam. The 7-acre berm was planted with California native plants and is the largest native landscaping project developed by the City of Los Angeles.

	In 1994, the City and Federal governments agreed to sharing the costs on $11 million in improvements in the Sepulveda Basin. The wildlife are was expanded 110 acres to the west of Haskell Creek (on either side of Woodley Avenue). Additional facilities in the wildlife area included trails, restrooms and staging area, signs, benches, viewing blinds and parking. This project was completed in 1999.
