A six-member research team flies by helicopter to spend five days studying the winter water quality of the Lake.
Canteen Corporation of Oregon changes its name to the Estey Corporation, though the local name of the business remains, Crater Lake Lodge, Inc.
A federal appeals panel rejects a challenge by environmentalists against exploratory drilling for geothermal energy near Crater Lake. The Interior Board decided that the BLM had prepared an adequate environmental analysis allowing California Energy to drill two test holes on the Park’s east boundary.
A federal judge stops logging on a 1,000 acre tract in near the Park boundary in Winema National Forest in the Prophecy burn.
The MT reports that the Park Service has decided to close the Lodge. Superintendent Benton claimed, “The dead weight of the building would cause the Great Hall to collapse. The decision was made purely on the basis of public safety.” The 1989 fiscal budget appropriates $1.76 for Lodge planning. The Lodge’s closure speeds along plans and money appropriation and design work for the building’s reconstruction. Public support for a rehabilitated Lodge continues to drive Congressional backing for the entire redevelopment package.
Morton Clark of Grants Pass, loses the engine of his Waco UPF-7 biplane trainer while flying over Crater Lake. The engine dies completely. “It was 2 to 3 minutes before I could get the engine started again, and all the time, my wife and I are circling over the lake wondering how cold the water was.” The Clarks dropped 1500 feet-even with the Rim before the engine was restarted.

A mysterious aqua-blue pool of a strange liquid is discovered at the bottom of Crater Lake. The pool measures about 2 meters wide by 8 feet long. It is near the lush white and orange bacterial mats found last summer. There is a yellow rim surrounding the pool. The temperature of the pool was about 40.1 degrees F (4.5 C), one degree warmer than the surrounding Lake water. A new mite, called the Crater Lake mite was discovered the previous week. The mite is a new species that eats algae. Algae lives in the Lake up to 450 beneath the surface. Below 150 feet the Lake temperature only changes half a degree.
Deep Rover measures water temperatures of 17.7 degrees C while probing bacterial mats at the bottom of the Crater Lake. That temperature is 14.2 degrees C higher than the surrounding Lake water. The new temperature reading is also higher than summertime surface temperatures.
Summer Conclusion of Lake Exploration with Deep Rover: The Blue pools (Llao’s Bathtubs) are 10 times more saline then the surrounding Lake water. Blue pools within a blue lake. The temperature variation ranges from 38 degrees to 68 degrees inside the bacteria mats, which are 3 – 4 inches deep and of unknown origin.
The Hydro thermal inflow is estimated at 200 – 300 liters per second. Heat input, measured at 15 – 20 mega watts, is spread out immediately over a large area. Thermoclines create a lake water turnover every 1 – 4 years.
30 foot chimney-like spires found extending upward from the bottom of the Lake, near the sides. Most likely fossilized remains of extinct hot springs. On the Crater wall is a 300 foot wide band of moss beginning 100 feet below the surface, completely encircling the caldera. Some mosses discovered are found only in Crater Lake.
Only 2% of the caldera floor and walls were visually explored. Midge fly worms (larva) were found crawling in the light gray pumice sediment on the Lake floor, leaving behind a crawl trail behind. During the summer the larva change to the pupa stage, float 2,000 feet up to the surface, where they become midge flies. Living only two or three days, the midges lay eggs on the Lake surface and die. The eggs sink to the bottom of the Lake, where they hatch and begin the cycle all over again.
Final Conclusions of Deep Rover’s Lake Survey: As a result of the past three years, we concluded that there are inputs of hydrothermal fluids in the bottom of Crater Lake. The dissolved materials associated with these thermally and chemically enriched fluids, coupled with the overall hydrologic balances, control the observed chemical composite of the lake. Because hydrothermal input dominates the material fluxes of most chemical into Crater Lake, the hydro thermal process is highly significant. Furthermore, the geothermal inputs have a direct effect on the density structure of the deep lake and consequently the rate of heat, salt and nutrients redistributed.
Only 130 bull trout found in Sun Creek. A 1947 survey found 3,000.
Park Officials express concern that Crater Lake has become an “island of trees” in a surrounding sea of forest clear cuts. “Our security blank for the past 87 years of being surrounded by three national forests has been stripped away and this is having an effect on the park’s wildlife.”
