TranscriptionSegment 71 Lahontan Cutthroat Trout Air Date: June 15 Anchor Intro: Waterways from Lake Tahoe to Pryamid Lake once teemed with the native Lahontan Cutthroat Trout. But, by the early 1930s, the Lahontan Cutthroat was extinct in Lake Tahoe and barely hanging on in Pyramid Lake. In tonight's Lake Tahoe Report, Shelly Purdy takes a look at efforts to reintroduce the fish to Tahoe. ((TAKE PKG)) ((nats water in creek)) ((Track 1)) Here at Fallen Leaf Lake, there are Lahontan Cutthroat Trout in the water…but only because they've been put here. Scientists are using Fallen Leaf Lake as a test study for Tahoe. ((Sot @ 2:33 Brant Allen, UC Davis Researcher)) "The fish have gone in and we are looking at how they survive in the lake and the reason we're using Fallen Leaf lake is really it's a smaller system that we can study and get ideas for other lakes in the Truckee Watershed. If we were to use Lake Tahoe, Tahoe is very vast and you could put a lot of fish in there and never find them." ((track 2)) Researchers are trying to figure out how the trout spawn, how quickly they grow and how they feed in the lake. But the most important thing they want to know is if the fish can survive here without being eaten by non-native fish. Because about the time the Lahontan Cutthroat became extinct in Tahoe and its tributaries, various non-native species of fish were introduced in an effort to boost the commercial fishery. When thousands of small Lanontan Cutthroats were stocked in Fallen Leaf Lake two summers ago…most of them were eaten by those other fish. But last summer, Fallen Leaf was stocked with larger Cutthroats…and so far they've done very well. ((s/u @11:45 Shelly Purdy)) "A project like this certainly isn't easy and it's going to take researchers many many years to figure out if they can even do it." ((sot @5:22)) "Long term goal would be to have a recreational fishery in Fallen Leaf Lake based on native fish that is able to self sustain itself through spawning and natural stream settings and long term is maybe 20 years out." ((track 3)) If this project is successful, it means a native species will be back where it should be…thriving in it's natural habitat. With the Lake Tahoe Environmental Education Coalition, I'm Shelly Purdy for kolo news channel 8. Anchor Tag: Those larger fish that Shelly mentioned were stocked in Fallen Leaf Lake last summer and are doing well…researchers expect that they should spawn for the first time next year.
