Tues 7/28/2015 TILAPIA - CONFIRMED 
fishing remains open after planting
Please note that these are tentative dates and are subject to change. Any changes will be announced on this page. Unless otherwise noted, the Lake is closed to all fishing from the start of stocking for the rest of the day.


Lake Mission Viejo experienced a serious loss of our fish population in November when an aquatic pest algae by the name of "Prymnesium parvum", never seen before in our lake, appeared. When this Golden Algae released its toxin, it damaged the gills of fish and compromised their ability to breathe despite good oxygen levels in our lake. Humans and other non-gill-breathers were not affected by the toxin.

Golden Algae, present in Texas and Arizona since the mid 80's, first appeared in California in the fall of 2013 at East Lake in Yorba Linda. Several other lakes in Southern California were stricken with Golden Algae during the following year, but LMV tested negative.
Fish began dying in LMV on November 10th but when the water was tested again, it was found to have almost undetectable levels of the golden algae. Over the next several weeks almost all of the fish died in LMV beginning with the bass then sunfish, and finally the catfish.

LMVA staff has reached out to the scientific community, speaking with a number of different researchers and governmental agencies to survey the science, history, and efforts to eradicate Golden Algae from other lakes, ponds, and rivers across the country. The difficult news is that there is no sure treatment available to rid LMV of this algae. LMVA’s treatments with algaecide targeting Golden Algae has resulted in some success and we are refining our rapid response plan in the event of another event. The golden algae have not gone away but have merely stopped producing the toxin. Reports indicate that toxic events have been more common during the colder months.
Unusual fish behavior may be our best indicator of another recurring event. That behavior includes near-shore mass schooling of non-feeding fish that frequently "yawn", shake their heads and jump as well as having a blotchy skin appearance.

LMVA Board and staff are hard at work seeking a solution that will return LMV's fishery to a stable and healthy state once again.
An unexpected benefit of LMVA's upcoming new Advanced Purified Water source just might be the inability of the Golden Algae to survive in LMV’s fresher waters! Thank you all for your concern and support as we attempt to solve this stubborn problem.



** If you own your own boat, make sure it is currently registered with LMV and has passed our Quagga Mussel quarantine process. Failure to comply with LMVA registration requirements will stop you from launching your boat. For more information, contact the LMV membership office at (949) 770-1313, ext. 215.

** LMV rules prohibit anglers from fishing within 15 feet of any private dock, bulkhead, or beach area around the lake. Lifeguards strictly enforce fishing rules, thus providing a safe and enjoyable fishing experience for all LMV members. Thanks to your cooperation, LMV now enjoys World Class bass fishing status!

** The Lake's Bass slot limit has changed: Catch-and-Release of all Bass has been extended to year-round release until further notice. ALL bass must be released immediately to the spot where they were caught. (please review all Fishing Rules)



The Lake Mission Viejo Fishing Club is active during the trout season with monthly meeting and tournaments from November through March.

For more information about the Fishing Club or trout stocking/fishing schedules, please call 770-1313, ext. 235. Or better yet, fish around the Lake website.

Don't forget to say hello to the Lake Compliance Officers this season. They are on the lake to assist you with having a great day as well as advising anglers on current rules and regulations.
