during the past 40 years when the Lake has been partially
controlled by means of the old logging dam, and during
which period the navigation and resort interests have
taken the place of the lumber business in the commercial
aspects of the Lake.
The records show that during these 40 years the Lake has fluctuated to the extent of a little more than eight feet between low and high water marks. The landowners around the Lake are principally interested in its esthetic qualities as a basis for the commercial interests involved in the tourist traffic and summer resort business. These interests would naturally desire the Lake to be held at a fixed level.
Likewise the navigation interests which operate a large number of boats of various sizes would be best pleased with a stationary level of the Lake, in order that their wharves and boat routes might be built and maintained for a single level of the water.
On the other hand the natural conditions and the use of water for power and irrigation, which are among the older vested rights, require the Lake to be used to some extent as a storage reservoir, which implies a fluctuating level.
The whole problem is to reconcile these various interests so as to derive the greatest possible economic advantages while maintaining the great beauties of the Lake for those whose interests lie mainly in that direction.
There has been suspicion on the part of some of the riparian owners that either the power company or the Government, or both, have been entertaining ulterior motives with the purpose of drawing down the Lake to unprecedented levels and of extracting from the Lake an amount of water greater than the average annual inflow. It may be stated once for all that there has never been such a purpose and that all calculations of the available water in the Lake have been based upon a long record of seasonable fluctuations which prove that the average annual outflow from the Lake is about 300,000 acre feet.
All plans have contemplated
the use of only this average
amount of water annually.
The Lake has an area of 193
square miles. The elevation of its
high-water mark has been at
6231.3, whereas its low-water mark
is recorded at elevation 6223.1
above sea level.
Should the Government be successful in acquiring the outlet property from the power company by the condemnation suit now in court, it is proposed to operate the gates of the dam at all times so as to maintain the Lake at the highest level consistent with the maintenance of a desirable shore-line and the conservation of water for the public utilities. It is proposed never to draw the Lake below the previous low-water mark or to allow it to rise as high as the previous high-water mark, at which low and high limits damage in some degree was done to one or another’s interests
