Mont. Water Right Claim Examination R. 24
Flow Rate and Volume
RULE 24(a). Identifying flow rate and volume. Facts and
information concerning flow rate and volume for stockwater use
will be identified using information in the claim along with other
data gathered by the department.
RULE 24(b). Flow rate guideline. The flow rate guideline for
stock use within a basin or subbasin will be as follows:
(1) The flow rate guideline for wells, developed springs,
pumped diversions, or gravity flow pipelines will be 35 gallons per
minute.
(2) There will be no flow rate guideline for stock drinking
from the source either directly, from a ditch system, or from an
undeveloped spring. For these types of stock use, a specific flow
rate will not be decreed. A remark shall be added to the water
right abstract.
Example:
A SPECIFIC FLOW RATE HAS NOT BEEN DECREED
BECAUSE THIS USE CONSISTS OF STOCK DRINKING
DIRECTLY FROM THE SOURCE OR FROM A DITCH SYSTEM.
THE FLOW RATE IS LIMITED TO THE MINIMUM AMOUNT
HISTORICALLY NECESSARY TO SUSTAIN THIS PURPOSE.
(3) The flow rate guideline for reservoirs associated with
stockwater use claims will be as follows:
(i) For stockwater claims involving only water from
on-stream reservoirs a flow rate guideline will not be identified,
and a flow rate will not be decreed. A remark shall be added to
the water right abstract.
Example:
A SPECIFIC FLOW RATE HAS NOT BEEN DECREED FOR
THIS USE FROM THIS ONSTREAM RESERVOIR. THE FLOW
RATE IS LIMITED TO THE MINIMUM AMOUNT HISTORICALLY
NECESSARY TO SUSTAIN THIS PURPOSE.
(ii) For offstream reservoirs the flow rate guideline
for storage will be the capacity of the diversion and conveyance
system. If there is no information regarding the capacity of the
diversion and conveyance system, or the system is shared by more
than one claimant, the flow rate guideline of 35 gallons per minute
will be used.
RULE 24(c). Volume guideline. A volume for stockwater
claims will not be quantified except as directed by the water court.
When a volume is not quantified, the following remark shall be
added to the water right abstract.
Example:
THIS RIGHT INCLUDES THE AMOUNT OF WATER
CONSUMPTIVELY USED FOR STOCK WATERING PURPOSES
AT THE RATE OF 30 GALLONS PER DAY PER ANIMAL UNIT.
ANIMAL UNITS SHALL BE BASED ON REASONABLE
CARRYING CAPACITY AND HISTORICAL USE OF THE AREA
SERVICED BY THIS WATER SOURCE.
If the water court directs that volumes be quantified for certain
stockwater claims, the water court, in consultation with the
department, shall determine appropriate volume guidelines.
RULE 24(d). Examining flow rate and volume. When the
claimed flow rate or volume differs from the guideline, the
department will gather further data and facts in an attempt to
determine the actual flow rate or volume for the specific claim.
The claimant may be contacted pursuant to Rule 44, W.R.C.E.R.
Discrepancies that may require claimant contact include, but are
not limited to:
(1) the claimed flow rate exceeds the guideline established
for wells, developed springs, pumped diversion or gravity flow
pipelines; or
(2) the claimed flow rate for wells, developed springs,
pumped diversion or gravity flow pipelines appears to be in error,
inconsistent or insufficient to satisfy the purpose.
RULE 24(e). Decree exceeded. When the flow rate of a prior
decreed water right has been exceeded by respectively filed claims,
the parties involved may be contacted pursuant to Rule 44,
W.R.C.E.R. If the parties do not reach agreement among
themselves and correct the over claimed flow rate, the issue shall
be identified in the department's summary report to the water
court.
RULE 24(f). Changing flow rate or volume. The claimed
flow rate and claimed volume of a water right will not be changed
during the department's examination unless:
(1) amended by the claimant;
(2) clarified by the department;
(3) as authorized in parts (b) and (c) of this rule; or
(4) standardized as to units of measure according to Rule
4, W.R.C.E.R.
RULE 24(g). Summary report. In the summary report to the
water court, the department shall provide on each abstract the
following data and facts concerning the flow rate and volume:
(1) the claimed or clarified flow rate, or changes
authorized by this rule;
(2) the claimed or clarified volume, or changes authorized
by this rule;
(3) identification of unique aspects or features of the flow
rate and volume;
(4) a notation of changes made during the department's
examination; and
(5) remarks concerning unresolved issues or questions
about the claimed flow rate and volume such as the claimed flow
rate or volume to be decreed cannot be confirmed or appears
excessive for this purpose.
