Upper Blue River Gaging Station established in the early 1950's as part of the Army Corps of Engineers Snow Study. This gaging station was the lower one of three stations established on Blue River. Other stations were established at the confluence of Blue River with Mann Creek and Wolf Creek. This station was abandoned by the Corps in 1957 and early researchers at the Andrews Forest took it over and maintained records from it until the flood of 1965 destroyed the station. This is labeled WS 5 in the Andrews data banks.

This station was abandoned by the Corps in 1957 and early researchers at the Andrews Forest took it over and maintained records from it until the flood of 1965 destroyed the station. This shelter was used as a satellite cabin for the early snow study researchers. The main cabin was built at the confluence of Mann and Wolf Creeks with Blue River some seven miles up stream. The early researchers would snow shoe down to this shelter via the Blue River trail and spend the night here. The cabin, 8'x8,' contained two bunks and a small wood stove. The materials for its construction were hauled in by pack train from the Santiam Highway as there was no access from Blue River at that time. The shelter was still standing the summer of 1998. Dick Fredriksen is the PNW researcher in the photo.

This Leupold & Stevens Q-12 recording snow and rain gage was the first recording gage established on the Andrews forest. It was located at the confluence of Rd 1506 and 304. Precip records from this gage at this location began December 1, 1951, and continued until the end of September 1959. In January 1962 the gage was reestablished at the Saddle near the top of WS 1 where it produced records until 1965 . It was then moved to the Hi - 15 Met. Station site where it ran from September 1963 until October 1975. After that the gage was moved to the South Umpqua Experimental Forest and installed on July 28, 1976. It produced records there until January 13, 1981. The Gage was retired after that date.

The Lucky Boy Burn occurred on the West side of the present Blue River Reservoir above the Saddle Dam. This was the site of the Lucky Boy Cabin established by the Boy Scouts in the early 50's. The fire occurred in the late 50's and erosion from this site was of great concern to early Andrews researchers. Jack Rothacker is standing in one of the gullies created by erosion resulting from the fire. The Lucky Boy Cabin can be seen in the background just on the other side of Blue River. This photo was taken before Blue River Reservoir was constructed.

This photo shows the accumulation of logs and debris that piled up on the road below the WS 3 Gaging Station during the Christmas Flood of 1964. There were at least 3 different torrents that came down the channel during this storm. The first torrent consisted mainly of supersaturated soil and logs. It was mostly contained within the area behind the fill. The second slide, consisting of the same type of material, occurred some 15 to 20 hours later. This pulse came down on top of the already-filled channel and spilled over the road into Lookout Creek. The last slide, consisting mostly of gravel and rock, came to rest on top of the previous slides. This one did not spill over the road to the extent of the second pulse, possibly due to its smaller size and the heaviness of the the material. The amount of material which went over the road bank would probably amount to one-fourth of the material in the channel. A rough estimate of material deposited in the channel was about 27,000 yds. (Taken from the Report of the 1965 Survey of Sediment at Watersheds 1, 2, and 3). This photo was taken after the second pulse.

WS 3 flume was buried under some 14ft of debris material during the Christmas Flood of 1964. It took a couple of bull dozers about two weeks to clear out the channel and dig down to the old flume. The gage house, of course, was carried away by the debris torrent. The flume was salvaged with only the lower left quarter of the concrete portion broken off. The original flume was repaired and a new gage house was constructed in August of 1966.

B/W negative of the second sediment basin constructed in the WS 3 channel below the gaging station. This basin was constructed in December of 1965 by setting two cedar logs across the channel and fastening 3x12 inch planks in a vertical position to the upstream side of the logs. In 1966, retaining walls were built along the sides of the basin and another layer of 3x12 planks were nailed to the face of the dam.

This debris flow occurred on WS 3 during the flood of February 1996. It occurred between 5PM and 9PM on February 6th when heavy rain fell on 12 inches of fresh snow in the area. This torrent consisted mostly of gravel and stones with a much fewer number of logs and woody debris than came down channel during the 1964 storm. A few logs and and some material did slop over the road fill and ran into Lookout Creek but not to the extent of that in 1964. The estimated amount of material deposited in the channel behind the road fill was approx. 2,000 cu yds. The gaging station was again carried away by the debris torrent and the A-35 Stevens Recorder was found in Lookout Creek down stream near the HJA compound. The flume was again found under 14ft of material after considerable digging with an excavator.

The flume was uncovered from about 14' of deposited material, and the road and gaging station site were reestablished. Space for a new sediment basin was excavated; and, new fill and a larger culvert were installed at the road site along Lookout Creek.

The second reconstruction of the WS 3 gage house was accomplished during the summer of '97. This house was designed with the help of a contracted engineer and constructed "in house" by Andrews' personnel. The house was built as a break away structure that, if swept away by another debris torrent, would detach from the foundation and stilling wells without destroying them. This structure was also designed on a much larger scale to accomodate two types of water sampling equipment: Isco and the Fredriksen Proportional Sampler; two types of water level recorders; a telemetering radio system; and, a propane heater used to keep the water samplers from freezing.

WS 3 sediment basin was reconstructed after debris torrent form the '96 flood destroyed and buried the last basin. This new basin was designed and built to allow for the measurement and cleaning of bedload after individual storms during the winter. Previous basins were measured and cleaned only on an annual basis during periods of low flow in the summer months. The new basin is equipped with a bypass which allows for the diversion on moderate winter flows so the basin can be pumped of excess water, the bedload material can be measured and then removed with excavator and dump trucks. The concrete lined basin also allows for measurment and clearing of small deposits of bedload such as a few wheelbarrow loads if that type accuracy is needed to acess small storm deposition. This photo showes the excavation of a basin full of material coming from a recent storm in December.

Jacob Wyssen, owner of the Swiss-based Wyssen Skyline Crane Co. This company designed and built a 5-ton crane to handle the large trees growing here in the Northwest. The company contracted to harvest WS1 through a special negotiated timber sale contract with the Willamette National Forest. The Research objectives were to harvest this entire 237 acre watershed with this experimental skyline system, designed to harvest large, steep, forested areas without the necessity of the roads required with the current Northwest High Lead system of logging. Watershed 1 was to be completely clearcut without roads as a comparison with the treament on Watershed 3 which was to be 1/3 of the watersed harvested using a conventional High Lead logging system with roads.

Side view of the Wyssen Skyline Crane carriage specially designed to lift the huge old growth logs found in our Northwest forests. At times, large hemlock logs that were somewhat water logged from lying in the stream channel had to be cut to 8' lengths in order to be lifted and moved by the system. Limitations like this increased the harvest time of this watersed substantially.

WS 1 with harvesting about three-quarters completed by the Wyssen Skyline Crane system. Photo shows the carriage with a turn of logs being lifted to it for transport down the skyline to a landing at the bottom of the watershed. Late in the logging process the intermediate support tree system of suspending the skyline as shown in photo 32 was deemed too slow and new crossing lines (that needed to be shipped from Switzerland) were installed to cross the watershed from ridge to ridge at three locations from top to bottom. This then was the new system used to hang the skyline from. These crossing lines can be seen at the top of the photo.

Slash burning on WS 1 took place on 10/17/1966. Forest Service crews with drip torches started at the top of the watershed and worked their way back and forth across the watershed lighting small strips of slash and brush as they worked their way down to the landing at the bottom of the watershed. The next morning at 8:30 AM when this photo was taken a heavy cloud of smoke still hung over the area.

The WS 1 stream channel still remained heavily choked with logs after the slash burn (large logs generally don't burn well during a slash burn). There were far more logs in the channel now than were there before the logging operation and it was decided to use KV dollars to clean the introduced logs from the channel. (see photo 38)

WS 1 stream channel was cleaned by hand shortly following the slash burring operation. Loggers doing the work were told to cut only the logs introduced in the channel by the logging and leave the natural debris in the stream. They obviously didn't get all these instructions and pretty well cut most of the logs in the lower part of the stream channel into 18 to 20 inch rounds. They split the rounds into stove-wood-sized pieces and left them to rot or be washed out by high water. After the loggers received additional instructions, they left many more logs further up the stream channel.

WS 7 was the first watershed to receive a gaging in station in the Hi-15 three experimental watershed set which includes WS 6, 13 ha., WS 7, 15.4 ha. and WS 8, 21.4 ha. These watersheds are located on a S. aspect at around 1,000 meters elevation. They contain 130 year old Douglas Fir. An H-flume was installed at WS 7 in 1963, and a FW-1 recorder with a 7 day chart was used to measure water level. We soon learned that during snow storms at this elevation large chunks of snow would fall from the trees bombing the pool inside the H-flume. These bombings splashed water all over the place, throwing the pens off the recorder and plugging up the flume. Shelters were built over these H-flume installations shortly after they were installed. Al Levno is pictured here making a check at the installation during the first winter after construction in 1964. Snow shoeing was the only way to reach these watersheds during periods after heavy snowfall in the early days of the study.

Shelterwood cutting on WS 7 (15.4 ha) removed 60% of the total basal tree volume in 1974. Temporary spur roads were constructed across the middle of the watershed on down the Southwest ridge of the watershed. Logs in the upper 60% of the watershed were yarded by tractor. Skid trails were not preplanned, but operators were instructed for safety reasons to yard downhill to the upper spur road. Logs in the lower 40% of the watershed were yarded partially suspended by a skyline cable system. Broad cast burning occurred only in the lower half of the watershed in 1975.

July 16, 1979 was volunteer trail-construction day on WS 10. Close to 30 people from OSU and PNW came to the Andrews on this day to construct trails in WS 10. The trails were needed to direct the many researchers doing research on the watershed. Indiscriminate foot travel on the freshly logged, steep slopes of the watershed was creating excessive erosion and destroying invading vegetation.
