REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



Shareholders and Board of Trustees
Aquila Tax-Free Trust of Oregon
New York, New York


In planning and performing our audit of the financial statements of
the Aquila Tax-Free Trust of Oregon, as of and for the year ended
March 31, 2016, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), we considered
its internal control over financial reporting, including control
activities for safeguarding securities, as a basis for designing
our auditing procedures for the purpose of expressing our opinion
on the financial statements and to comply with the requirements
of Form N-SAR, but not for the purpose of expressing an opinion
on the effectiveness of Fund's internal control over financial
reporting.  Accordingly, we express no such opinion.

The management of the Fund is responsible for establishing
and maintaining effective internal control over financial
reporting.  In fulfilling this responsibility, estimates
and judgments by management are required to assess the
expected benefits and related costs of controls.  A company's
internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted
accounting principles.   A company's internal control over
financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the
company are being made only in accordance with authorizations
of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of a
company's assets that could have a material effect on
the financial statements.

Because of inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to
future periods are subject to the risk that controls may
become inadequate because of changes in conditions, or
that the degree of compliance with the policies or
 procedures may deteriorate.

A deficiency in internal control over financial reporting
exists when the design or operation of a control does not
allow management or employees, in the normal course of
performing their assigned functions, to prevent or detect
misstatements on a timely basis.   A material weakness is
a deficiency, or combination of deficiencies, in internal
control over financial reporting, such that there is a
reasonable possibility that a material misstatement of
the company's annual or interim financial statements will
not be prevented or detected on a timely basis.


Our consideration of the Fund's internal control over
financial reporting was for the limited purpose described
in the first paragraph and would not necessarily disclose
all deficiencies in internal control that might be material
weaknesses under standards established by the Public
Company Accounting Oversight Board (United States).
However, we noted no deficiencies in Fund's internal
control over financial reporting and its operation,
including controls for safeguarding securities, which
we consider to be material weaknesses, as defined above,
as of March 31, 2016.

This report is intended solely for the information and
use of management, Shareholders and Board of Trustees of
Aquila Tax-Free Trust of Oregon and the Securities and
 Exchange Commission, and is not intended to be and should
not be used by anyone other than these specified parties.
