defined, in way of judgment, mortgage or otherwise, and all real estate
as above defined acquired or used for railroad, highway, or other public

2. "Regulating reservoir" means a basin for impounding water, formed

water is or is to be impounded, the gate houses, including controlling
gates, sluices, screens, racks and other accessories thereto; spillways,
fishways, log or ice chutes, or barriers and all accessories thereto;
all bridges or roadways over or appurtenant to the dams and dikes; all
other structures, devices, or appliances connected with or appurtenant

they cannot be removed without injury to such structures or without
impairing the usefulness thereof for the purposes for which they are
intended; the lands under the water impounded, or to be impounded, by
the dam or dams, and such lands surrounding or adjacent to the dam, or

be necessary for the purposes of the construction, maintenance, or
operation of a regulating reservoir, as above defined, also including
such land surrounding such reservoir as may be necessary to preserve and
protect such reservoir from unsanitary conditions, and from any
encroachment affecting its use for the purpose of regulating the flow of
the stream or river for the regulation of which it may be constructed.
Such term is not intended to include a reservoir created by a dam
constructed or maintained for power purposes, but is intended to include
a reservoir at or by reason of which there may be, as an incident to the

the possibility of the utilization of a portion of the water stored
thereby for power purposes, without in any way interfering with the
primary purpose of a reservoir constructed under the provisions of title
21 of this article.

3. "Benefit or benefits" shall be interpreted to include benefits to
real estate, public or private, to municipal water supply, to
navigation, to agriculture and to industrial and general welfare by
reason of the maintenance and operation of a regulating reservoir,
whether such benefit shall inure to a person, a public corporation or
the state. In the event that any regulating reservoir operates to
relieve the state of any obligation by reason of diversion of the water
of any river for canal purposes, the state, to the extent that the
maintenance and operation of such reservoir may accomplish such relief,
shall be deemed to have received benefit therefrom.

4. "Board" shall mean the river regulating board of a district.

water flowed by any stream or river, at the location thereon where the
measurement is taken, in one year, or for an average of years, by the
number of seconds in a year.

8. "Average normal flow" means that result in terms of cubic feet of
water per second derived by the division of the total number of cubic
feet of water flowed by any stream or river, at the location thereon
where the measurement thereof is taken, on those days in a year during
which such flow did not exceed the average flow, by the number of
seconds in the total number of such days.

9. "Cost of construction" shall be construed to include in addition to
the cost of a regulating reservoir, all preliminary expenses, all
expenses of organization of the district, engineering fees, costs of

construction of such reservoirs up to time of the completion thereof.

10. "Cost of maintenance and operation" shall be construed to include
all such expenses for repairs and upkeep of the regulating reservoir,
all such expenses necessary to the proper operation of such reservoir
for the purposes for which it was constructed and all such part of the
compensation and expenses of the board, its officers and employees after
the completion of such regulating reservoir as are in the judgment of
the board and the department properly chargeable thereto.

11. "High flow line" means the line which will be made around a
reservoir by the water therein when it is at the level of the crest of
the reservoir spillway.

12. "Low flow line" means the line made by the water of a reservoir
when it is at the lowest level which, consistent with the regulation of
the flow of the river and the maintenance of sanitary conditions, the
