|2/21/1952||Report on Survey for Flood Control of Skagit River and Tributaries||“The existing reservoirs are not effective in preventing major flooding in the Skagit Valley, Diablo Reservoir is ordinarily maintained at a high level by Ross storage and has no flood storage, Shannon Lake is likewise held at a high level if stream flow permits, but an incidental degree of minor flood protection might be available if the reservoir should be drawn down because of deficient run-off before a flood, Ross Reservoir above Diablo has a large amount of storage, primarily for power, but the Federal Power Commission has required a reservation of winter flood control storage space. Studies are under way to determine the amount of such storage, and it is believed that it will not exceed 200,000 acre-feet. Because of its far upstream location Ross Reservoir storage cannot greatly reduce major floods on the lower Skagit River, The effectiveness of Ross storage in reducing peak discharges depends upon location of the storm center and other variable storm characteristics, Estimates based on average conditions indicate that crest reductions varying between 15,000 and 25,000 second-feet may be expected at Sedro Woolley.”|

|8/1/1963||Lower Sauk River Dam Analysis & Pertinent Data||Analysis of power requirements for potential dam on the Sauk River encompassing 712,000 acre-feet of which 200,000 acre-feet was to be used for flood control storage.|
|9/30/1963||"This proposed project would involve the building of a dam some four and a half miles above the mouth of the Sauk River. Construction of this dam would result in the destruction of a large portion of our King Salmon and Steelhead spawning grounds."|
|11/1963||Unregulated 100yr fld 250,000 to 300,000 cfs (pg 2); The 35-year level of flood protection provided by the Avon Bypass with levee and channel improvements would protect against 79 percent of average annual flood damages under present conditions. These flood damages are 75 percent agricultural and only 25 percent urban. Therefore, the project is now required essentially for the protection of agricultural lands, and the 35-year level of protection is well suited to present development. . . . The semi-pervious foundation conditions preclude any general raising of levees without extensive broadening of the levee sections, construction of cutoffs to reduce seepage, and relocation of the road systems adjacent to the levee system. (pg 4) To achieve the same results as the Bypass and levee improvements, the channel would have to be widened from 300 to 600 feet from the downstream limits of Sedro Woolley to the mouth of the river, a distance of over 20 miles. (pg 6) ... At Mt. Vernon the 1932 flood of 140,000 c.f.s. has a 12-year frequency; the 1921 flood of 182,000 c.f.s. has a 30-year frequency; and a flood of 245,000 c.f.s, would have a 100-year frequency. ... 278,000 at SW (Table 2)|
Memo to Portland District fm Seattle District re Reactivation Report for Avon Bypass
|The lower Sauk River is the only location in the Skagit River basin at which major upstream storage is possible. At such time as other multiple purpose uses for storage require development of the Sauk site, sufficient flood control storage could be included to increase the 30-year protection that would be provided by the bypass and improved levee system to more than 100-year protection.|
|9/8/1964||Disposition Form re: Preliminary Sauk River storage determinations||
a. Storage in the amount of 134,000 acre-feet is
required in the Sauk River Reservoir to control a
100-year flood to 180,000 c.f.s. at Mt. Vernon.
b. A 30-year flood, requiring 130,000 acre-feet of storage in Sauk River Reservoir, is the maximum flood that can be controlled to 120,000 c.f.s. at Mt. Vernon.
c. A 10-year flood, requiring 77,000 acre-feet of storage in the Sauk River Reservoir, is the maximum flood that can be controlled to 91,000 c.f.s. at Mt. Vernon.
|7/9/1965||Series of MFRs & Letters Mostly Addressing 8 Possible Dam Sites and Impacts of Wild and Scenic River Act||
7/9/65 8 sites were Cascade River, Lower Suiattle
River; Upper Suiattle River; Upper Sauk River; Lower Sauk River; Cooper Creek;
Thunder Creek; and Faber site (on Skagit about 6 miles upstream from Baker
River). 7/1/65 "A decision to commit a portion
o the river basin to a Wild (and Scenic) River category appears premature at
this time. 6/18/65 "One hundred year flood
protection is vitally necessary for continued progress in Skagit county.
6/29/65 The purpose of this meeting was to inform
Seattle Light representatives of our proposed upstream storage studies in the
Skagit River basin, determine sites at which City Light has made studies, and
obtain data on power studies made by the city. 4/7/65
Ltr fm private engineering company to Corps re Cape Horn.

"This report covers certain geologic phases of upstream storage -sites as viewed
on a 5-day reconnaissance by Messrs. A. S. Cary, F&M Branch and W. R. McKinley,
Project Planning Branch, into the Skagit drainage area." . . . The Skagit
Valley far upstream has a depth of fill near 500 feet and if the rock floors of
the Sauk and Skagit are concordant, the depth is well below sea level."

|8/25/1967||DRAFT Resolution from WRAC to County Commissioners||Purpose of FCZD was to raise taxes for flood control activities. Agreed to comp plan (attached) that would raise levees to 8 year protection to include "fuse plugs" to eliminate critical levee failures. In addition, a program of public information and control of the flood plain will be adopted to insure that developments are controlled and a false sense of security does not exist.|
|4/29/1974||Skagit Conservation District ltr to Corps re Wild and Scenic River System designation for the Sauk River||SCD didn't want designation because it would eliminate flood control structures on the Sauk River. SCD demanded that "a feasibility study be made of both the Sauk River flood control structure and the Avon Bypass by the COE before allowing any classification of the river.|
|Skagit Conservation District ltr to Corps||SCD wanted public meeting in Sept. so the Corps could discuss Sauk River dam and Avon Bypass concepts and the impacts of the Wild & Scenic River act because, "It has been a long time since either the Avon Bypass or the Sauk Dam have been discussed here."|

|1/14/1977||Draft letters to the President from Dept. of Agriculture and the ACOE||
The documents represent what happens when there are one too many agencies trying to comment on a flood project when one of the agencies doesn't know anything about the flood issue.
The Dept. of Ag stated, "In addition, the Department of the Army, in their response to the study report, pointed out that designation of the Sauk River would preclude construction of, a flood control storage project on the river. However, alternatives to the Sauk River site exist which would provide the same degree of flood protection for downstream areas.The ACOE responded ORIGINALLY with, "We have never provided such information to them. From a practical standpoint, approx. 40% of the unregulated flow in the lower Skagit river basin comes from the Sauk River. Levee system's heights in the lower Skagit basin are limited by foundation conditions. Accordingly, it is considered that there is no alternative to flood control storage on the Sauk River. We would suggest that the above quoted sentence be deleted." Upper level management tuned it down a little, see Insert A.
|7/18/1977||Letter to Corps Headquarters from Congressman Lloyd Meeds re Sauk River dry dam.||Asked the following questions: 1)How much flood protection would be provided; 2)Will a dry dam on the Sauk be engineeringly sound, economically justified and environmentally safe?; 3) What type of time frame needed for study.|
|7/27/1977||Corps MFR re responses to 7/18/1977 letter from Congressman Meeds re "Dry Dam" on Sauk River||A "dry dam" for FC only would be "engineeringly sound." The economic justification has not been determined in any studies and would not be available until after re :on level survey studies. We do not understand the term "environmentally safe" but do believe an "environmentally acceptable" project could be formulated. A detailed study of the Sauk could be completed in 4 years at the cost of $400,000. Checkpoint 1 could be reached in 1-1/2 years at a cost of $150,000.|
