No. 18SA216, Concerning the Application for Water Rights of S. Cade Huffaker and 

Bradley H. Huffaker in the Conejos River or its Tributaries in Conejos County; and No. 

18SA217, Concerning the Application for Water Rights of Lee Crowther in the Conejos 

River or its Tributaries in Conejos County—Water Rights—Postponement Doctrine—

Priority. 

These appeals concern a dispute over competing rights to irrigation tail and waste 

water that collects in a borrow ditch. The supreme court is asked to determine whether 

a driveway that interrupts the flow of water in the ditch renders the sections of borrow

ditch on either side of the driveway separate sources of water for purposes of the

postponement doctrine. 

The supreme court holds that because the water that collects in the sections of the 

borrow ditch at issue here generally derives from irrigation of the same fields and because 

the water routinely overflows the driveway and rejoins the ditch on its northward course, 

the water in the ditch on either side of the driveway constitutes the same source. The 

postponement doctrine therefore applies to determine the relative priorities of the 

applicants’ competing rights. Under that doctrine, the applicants who filed their

application in an earlier calendar year are entitled to the senior rights. The court therefore 
reverses the judgment of the water court and remands these cases with directions to 

revise the applicants’ decrees consistent with this opinion.

JUSTICE MÁRQUEZ delivered the Opinion of the Court.
3

¶1 The appeals in these cases from Water Division 3 concern a dispute over rights to 

irrigation tail and waste water that collects in a borrow ditch1 along a section of County 

Road 19 in Conejos County. S. Cade Huffaker and Bradley Huffaker (collectively, the 

“Huffakers”) and a neighboring landowner, Lee Crowther, filed competing applications 

for rights to this water. The Huffakers filed their application in 2013; Crowther filed his 

in 2016.

¶2 The Huffakers argue that under the postponement doctrine, they are entitled to 

the senior right in the borrow ditch water because they filed their application first. Under 

that doctrine, two dates are critical in determining the priority of rights adjudicated on 

the same source of water: (i) the date the application was filed, which sets the calendar 

year the water right was filed and establishes priority over filings in subsequent calendar 

years, and (ii) the date the first step toward appropriation was taken, which establishes 

the relative priority of water rights applied for in the same calendar year. § 37-92-306, 

C.R.S. (2018); Matter of Bd. of Cty. Comm'rs of Cty. of Arapahoe v. United States, 891 P.2d 952, 

964 (Colo. 1995); see also Dallas Creek Water Co. v. Huey, 933 P.2d 27, 35 (Colo. 1997). 

¶3 The water court held that the postponement doctrine does not apply here because 

it concluded that the water rights claimed by the Huffakers and Crowther do not derive 

from the same source. A dirt and gravel driveway blocks the ditch as it flows north and 

 

1 A borrow ditch is a “ditch dug along a roadway to furnish fill and provide drainage.” 

Borrow ditch, 2019 Merriam-Webster Online Dictionary, https://perma.cc/36RH-RKRZ.
4

channels water into a culvert that Crowther uses to deliver the water under County Road 

19 to his fields. Although the water frequently overflows this driveway, runs down the 

road, and flows back into the ditch, eventually reaching the Huffakers’ point of diversion 

farther north, the water court reasoned that because the driveway directs much of the 

water into Crowther’s culvert (thus preventing it from reaching the Huffakers’ point of 

diversion), the section of borrow ditch south of the driveway is not a source of the 

Huffakers’ water. The court further concluded that the collection area for the Huffakers’ 

right begins north of the driveway, not farther south at the same point as Crowther’s 

right. Having concluded that the postponement doctrine does not apply because the 

rights claimed do not derive from the same source, the court held that Crowther’s right 

to divert water at the culvert was not junior to the Huffakers’ right, even though 

Crowther’s application was filed two and a half years after the Huffakers’ application. 

¶4 The Huffakers appeal, again contending that the postponement doctrine applies

to determine the priority of the applicants’ competing rights to the water in the borrow 

ditch, and that they are entitled to the senior priority because they filed their application 

first. They further argue that the collection area of their absolute water right begins not 

at the driveway, but farther south (upstream) at the same point as Crowther’s right. We 

agree with both contentions. 

¶5 We hold that the water court erred in concluding that the postponement doctrine 

does not apply in this case. The water that collects in the sections of the borrow ditch at 

issue here generally derives from irrigation of the same fields; moreover, this ditch water 

frequently overruns the driveway, floods the road, and returns to the ditch on its 
5

northward course. In short, the water in the borrow ditch south and north of the 

driveway constitutes the same source of water, irrespective of the driveway. Because the 

Huffakers and Crowther seek competing rights in the same source of water, the 

postponement doctrine applies, and the Huffakers are entitled to the senior right. We 

further hold that the water court erred in concluding that the collection area for the 

Huffakers’ absolute right starts north of the driveway and not farther south at the same 

point as Crowther’s right. Accordingly, we reverse the judgment of the water court, and

remand these cases with directions to revise the applicants’ decrees consistent with this 

opinion. 

I. Facts and Procedural History

¶6 The irrigation tail and waste water at issue here accumulates in the L.N. Bagwell 

and Sons Seepage and Drainage Ditch (“borrow ditch”), located along the western edge 

of Conejos County Road 19. The water in the borrow ditch varies from year to year, 

depending on the irrigation practices upgradient of the ditch on the west side of County 

Road 19. County Road R (which runs west to east) intersects County Road 19 to the north 

of the ditch water collection area. Lee and Grace Bagwell (collectively, the “Bagwells”), 

Crowther, and the Huffakers each own parcels of land to the east of County Road 19, and 

all deliver water from the ditch to their respective properties through culverts under 

County Road 19 as the water flows south to north. 

¶7 The Bagwells’ property lies farthest south, upstream of Crowther’s and the 

Huffakers’. The Bagwells have a decree for the tail water that collects in the section of 

the borrow ditch across County Road 19 from their property. They deliver this water 
6

through a series of culverts, the northernmost of which is located about 3,377 feet south 

of the intersection of County Road 19 and County Road R.

¶8 Crowther owns 160 acres directly north of the Bagwells’ property. His property 

extends north up to County Road R. Crowther has delivered the borrow ditch water to 

his land using three culverts that run west to east, two of which are relevant here. Culvert 

Number 1, the southernmost of Crowther’s culverts, is about 2,630 feet south of County 

Road R. The middle culvert, Culvert Number 2, was approximately 1,350 feet south of 

County Road R. Several years ago, Conejos County removed Culvert Number 2 at the 

request of the Huffakers, but the County has indicated it is willing to reinstall the culvert

if Crowther is granted the right to divert water from the borrow ditch at this location. 

¶9 The Huffakers own property immediately north of County Road R, namely, the 

southwest quarter of Section 8, Township 34 North, Range 10 East, N.M.P.M. (the 

“Huffakers’ property”). In 1952, the Huffakers’ great-grandfather, Luther N. Bagwell, 

filed a map and filing statement for the L.N. Bagwell & Sons Seepage and Drainage 

Ditch—the borrow ditch at issue here. Luther Bagwell owned the Huffakers’ property 

until 1977, when he conveyed it to the Huffakers’ parents. The Huffakers acquired the 

property in 2010. The Huffakers deliver the borrow ditch water to their land by fluming 

water under the intersection of County Road 19 and County Road R. From there, the 

water runs east in a ditch that previously was flumed over the Ephraim, Richfield, and 

Sanford canals to irrigate the entirety of the Huffakers’ property. The flume system has 

since deteriorated, and only about 75 acres west of the Ephraim Ditch are currently 

irrigated. 
7

¶10 On December 24, 2013, the Huffakers filed an application in Case No. 13CW3012, 

seeking absolute and conditional rights in the ditch water to irrigate their property. At 

this point, the Huffakers seek an absolute right to 8 cubic feet per second (“c.f.s.”) from 

the borrow ditch to irrigate the 75 acres west of the Ephraim Ditch, and a conditional 

right to use the same 8 c.f.s. to irrigate another 85 acres east of the Ephraim Ditch.2 The 

Huffakers measured peak flow in the borrow ditch near their point of diversion at 9.1 

c.f.s. in 2016, and 7.3 c.f.s. in 2017. 

¶11 The Huffakers’ application seeks to use water that collects in the section of borrow 

ditch reaching from the Bagwells’ previously decreed point of diversion at their 

northernmost culvert—about 3,377 feet south of the intersection of County Road 19 and 

County Road R—up to the Huffakers’ point of diversion at that intersection. The 

Huffakers claim they are entitled to the water that collects in this 3,377-foot stretch of 

borrow ditch because the 1952 map of the L.N. Bagwell Seepage and Drainage Ditch 

appears to indicate that all of the water collected in the borrow ditch for one mile (or 5,280 

feet) south of the intersection of County Road 19 and County Road R was intended to 

irrigate what is now the Huffakers’ property. Their application listed May 5, 1952 as the 

date of appropriation.3 

 

2 The Huffakers’ 2013 application initially sought an absolute right to 17.9 c.f.s.

3 This date of appropriation presumably derives from the map and filing statement filed 

by Luther N. Bagwell, reflecting that survey work on the L.N. Bagwell & Sons Seepage 

and Drainage Ditch commenced on that date. 
8

¶12 Crowther filed a statement of opposition to the Huffakers’ 2013 application, 

claiming that he owned rights in the same ditch water. Two and a half years later, on 

September 29, 2016, Crowther separately filed an application in Case No. 16CW3013, 

seeking a decree to use a total of 10 c.f.s. from the borrow ditch: specifically, an absolute

right to 7 c.f.s. at Culvert Number 1, and a conditional right to an additional 3 c.f.s. at

Culvert Number 2. Crowther’s application likewise listed May 5, 1952 as the date of 

appropriation for these rights. The Huffakers filed a statement of opposition, claiming 

that under the postponement doctrine, their rights to the water in the borrow ditch are 

senior to the rights sought by Crowther in his application.

¶13 With the parties’ agreement, the water court consolidated the two cases

(13CW3012 and 16CW3013). At trial, the Huffakers argued that because the competing 

applications here seek rights in the same water, and because the Huffakers filed their 

application first, they are entitled to the senior right in the borrow ditch water based on

the postponement doctrine. The water court disagreed, concluding that the 

postponement doctrine does not apply here because the sections of the borrow ditch 

south and north of the driveway do not constitute the same source of water. 

¶14 Immediately north of Crowther’s Culvert Number 1 lies a raised dirt and gravel 

driveway used to enter a field lying west of County Road 19. This driveway, which has 

existed for at least 30 years, intersects the borrow ditch and lacks a culvert. The driveway 

thus blocks the water in the borrow ditch and directs water into Crowther’s Culvert 

Number 1. However, the ditch water frequently overflows the driveway, enters the road, 

and collects back in the ditch north of the driveway. From there, the water continues 
9

north past Crowther’s other culverts where it eventually reaches the Huffakers’ point of 

diversion at the intersection of County Road R and County Road 19. 

¶15 The water court reasoned that to the extent the driveway blocks the ditch and 

directs water into Crowther’s Culvert Number 1, the section of the borrow ditch south 

(upstream) of the driveway is not a source of the Huffakers’ water. In so doing, the court 

likened the driveway intersecting the borrow ditch here to the mountain range that 

separates the North Fork and the South Fork of the South Platte River discussed in South 

Adams County Water and Sanitation District v. Broe Land Co., 812 P.2d 1161, 1167 (Colo. 

1991): 

In [South Adams County], the Colorado Supreme Court affirmed the water 

court’s decision that the postponement doctrine did not apply to make 

water rights on the North Fork of the South Platte River adjudicated in 1913 

subordinate to water rights adjudicated in 1889 on the South Fork of the 

South Platte because “the North and South Forks are separated by a high 

mountain range” and, thus, there could be no conflict of right between the 

water users on the two forks of the river. 

The situation in the current case is similar. Here, rather than a high 

mountain range between the points of diversion of the two water rights 

there is a driveway without a culvert that blocks water in the borrow ditch 

south of Mr. Crowther’s Culvert Number 1 from travelling north into the 

borrow ditch north of Culvert Number 1. Much of this water is diverted 

into Mr. Crowther’s Culvert Number 1 and cannot reach the Huffakers’ 

point of diversion. To the extent that Culvert Number 1 stops the water 

from travelling north to the Huffakers’ point of diversion, this portion of 

the borrow ditch is not a source of the Huffakers’ water. 

¶16 Because it concluded the source of the Huffakers’ water right is different from the 

source of Crowther’s water right, the court held the postponement doctrine does not 

apply and Crowther’s right to divert water from the ditch at Culvert Number 1 is not 

junior to the Huffakers’ right to this water. At the same time, the court acknowledged 
10

that the water in the borrow ditch frequently overflows the driveway and returns to the 

ditch, eventually reaching the Huffakers’ point of diversion. The court thus concluded 

that the Huffakers have appropriated this water—that is, the excess beyond what 

Crowther has appropriated through Culvert Number 1. 

¶17 Based on this reasoning, the court entered decrees in 13CW3012 and 16CW3013, 

awarding Crowther a conditional right4 to 7 c.f.s. of water in a collection area south of the 

driveway and awarding the Huffakers an absolute right to 8 c.f.s. of water in a separate 

collection area north of the driveway to irrigate the 75 acres west of the Ephraim Ditch. 

The court also awarded the Huffakers a conditional right to 8 c.f.s. of “excess water”

accumulating in the ditch south of Crowther’s Culvert Number 1 to irrigate 85 acres east 

of the Ephraim Ditch, but ruled that this conditional right is junior to Crowther’s 

conditional right to 7 c.f.s. in this water. Further reasoning that it “serves no party to 

have the water spill out into the road,” the court ordered the Huffakers to install a culvert 

under the driveway. The court also ordered the parties to share the cost of constructing 

a water structure that will allow Crowther to first divert his water through Culvert 

Number 1 and allow excess water to flow through the new culvert under the driveway 

and down the borrow ditch to the Huffakers’ point of diversion. 

 

4 The court awarded Crowther only a conditional right to the 7 c.f.s. because he had not 

installed any measuring devices at his diversion structures, and the evidence at trial did 

not establish the amount of water he has applied to beneficial use through Culvert 

Number 1 or Culvert Number 2. 
11

¶18 Finally, the court also awarded Crowther a conditional right to another 3 c.f.s. of 

water at his Culvert Number 2 in a collection area north of the driveway, based on the 

county’s anticipated reinstallation of that culvert.

5 The court ordered Crowther to install 

a measuring device at Culvert Number 1 and a gate or other means to shut off diversion 

from Culvert Number 2 any time his right there is not in priority and there is an unmet 

call from the Huffakers on the ditch. 

¶19 The Huffakers now appeal the water court’s rulings.

6 The key disagreement

between the Huffakers and Crowther concerns the water that collects in the stretch of 

borrow ditch between the Bagwells’ northernmost culvert and Crowther’s Culvert 

Number 1. The Huffakers argue that the postponement doctrine dictates that the 

Huffakers’ 2013 application is senior to Crowther’s 2016 application for water from the 

same source, and that the water court erred in holding otherwise. Relatedly, they argue 

that the water court erred in describing the collection area for the Huffakers’ absolute 

water right as beginning at the driveway immediately north of Crowther’s Culvert 

Number 1, rather than at the Bagwells’ northernmost culvert, i.e., the Bagwells’

previously decreed point of diversion 3,377 feet south of the intersection of County Road 

19 and County Road R. Crowther did not file a brief in response. 

 

5 Crowther conceded that any rights diverted from Culvert Number 2 are junior to the 

Huffakers’ claims.

6 After consolidating 13CW3012 and 16CW3013 for trial, the court issued a combined 

ruling containing its findings, conclusions, judgment, and decrees. The Huffakers filed 

appeals in both cases. 
12

II. Standard of Review

¶20 We accept the water court’s factual findings on appeal so long as they find support 

in the record. Burlington Ditch Reservoir & Land Co. v. Metro Wastewater Reclamation Dist., 

256 P.3d 645, 660 (Colo. 2011). We review de novo the water court’s legal conclusions, 

including its interpretation of prior decrees. Id. at 661. 

III. Analysis

¶21 We hold that the water court erred in concluding that the postponement doctrine 

does not apply in this case. The water in the borrow ditch south and north of the 

driveway constitutes the same source of water, irrespective of the driveway. Because the 

Huffakers and Crowther seek competing rights in the same source of water, the 

postponement doctrine applies. Under that doctrine, the Huffakers’ rights are senior to 

Crowther’s. We further hold that the collection area for the Huffakers’ rights starts at the 

Bagwells’ previously decreed point of diversion 3,377 feet south of the intersection of 

County Road 19 and County Road R. Accordingly, we reverse the judgment of the water 

court, and remand these cases with directions to revise the applicants’ decrees consistent 

with this opinion.

¶22 A water right is a judicial recognition of the application of water to beneficial use. 

§ 37-92-103(3)(a), (4), C.R.S. (2018). Notably, the applications here involve irrigation tail 

and waste water. The water court correctly recognized that neither applicant can acquire 

vested rights in this water because “an appropriator of waste water cannot obtain a right 

against the water waster to compel continuation of the waste water discharge.” City of 

Boulder v. Boulder & Left Hand Ditch Co., 557 P.2d 1182, 1185 (Colo. 1976). That said, the 
13

water court in Division 3 has a longstanding practice of resolving disputes between tail 

water users even if those rights do not compel continued tail water supply. 

¶23 The Huffakers argue that under the postponement doctrine, they are entitled to 

the senior right in the borrow ditch water because the applicants assert competing claims 

to the same water and the Huffakers filed their application first. We agree.

¶24 The postponement doctrine governs the administration of water rights 

adjudicated in different decrees or applied for in different years. City & Cty. of Denver By 

& Through Bd. of Water Comm'rs v. City of Englewood, 826 P.2d 1266, 1275–76 (Colo. 1992). 

This doctrine was developed by this court and later codified in statute. See South Adams 

Cty., 812 P.2d at 1163–64; United States v. Bell, 724 P.2d 631, 641 n.13 (Colo. 1986). 

¶25 Under the postponement doctrine, water rights adjudicated in a previous decree 

are senior to water rights adjudicated in a subsequent decree on the same stream, 

regardless of their dates of appropriation. South Adams Cty., 812 P.2d at 1164. Whereas 

section 148-9-13(3) of the 1943 Adjudication Act applied the doctrine according to the 

decrees in which the water rights were adjudicated, section 37-92-306 of the Water Right 

Determination and Administration Act of 1969 applies the doctrine according to the years 

in which the water rights applications were filed. City of Englewood, 826 P.2d at 1276 n.10; 

see also Dennett L. Hutchinson, Comment, Determining Priority of Federal Reserved Rights, 

48 U. Colo. L. Rev. 547, 554–55 (1977) (clarifying that the emphasis since the 1969 

codification of the postponement doctrine is “no longer on general or supplemental 

adjudications, but rather on filings and determinations during a calendar year, all of 

which are considered as one ‘adjudication’”). 
14

¶26 Thus, under the 1969 Act, two dates are critical in determining the priority of rights 

adjudicated on the same source of water: (i) the date the application was filed, which sets 

the calendar year the water right was filed and establishes priority over filings in 

subsequent calendar years, and (ii) the date the first step toward appropriation was taken, 

which establishes the relative priority of water rights applied for in the same calendar 

year. § 37-92-306; Cty. of Arapahoe, 891 P.2d at 964; see also Dallas Creek, 933 P.2d at 35. In 

other words, an applicant who files for a water right in one calendar year takes priority 

over applicants who file for water rights on the same source of water in subsequent 

calendar years, regardless of the dates of appropriation. City of Englewood, 826 P.2d at

1276; South Adams Cty., 812 P.2d at 1164. But among water rights filed in the same 

calendar year, the applicant who first appropriated the water takes seniority. § 37-92-306;

see also Concerning Application for Water Rights of Turkey Canon Ranch Ltd. Liab. Co., 937 

P.2d 739, 749 (Colo. 1997); Cty. of Arapahoe, 891 P.2d at 964. 

A. The Postponement Doctrine Applies Here to Entitle the 

Huffakers to the Senior Water Rights

¶27 We hold that the water court erred in concluding that the driveway blocking the 

borrow ditch in this case separates the water in the ditch south and north of the driveway 

into distinct sources such that the postponement doctrine does not apply to determine 

the priority of the applicants’ competing rights to the water in the borrow ditch. The 

water court’s reliance on South Adams County, in particular, was misplaced.

¶28 The issue in South Adams County was whether a 1913 decree adjudicating 136 

water rights on the North and South Forks of the South Platte River should be treated as 
15

an original adjudication such that those water rights should be administered by their 

appropriation dates as against all other vested rights on the South Platte, or as a 

supplemental adjudication such that those rights should be deemed junior to a 1889

general adjudication of diversion priorities on the South Fork of the South Platte basin. 

South Adams County, 812 P.2d at 1162–63. 

¶29 The water court held that the 1913 adjudication was intended to be an original 

adjudication for the water rights located on the North Fork and not a supplemental 

adjudication of the 1889 decree; thus, these water rights should be administered 

according to their appropriation dates. Id. at 1165. This court affirmed, reasoning in part

that even if the postponement doctrine existed at the time of the 1913 adjudication, the 

referee was not required to apply the doctrine to the North Fork water rights because the 

1913 decree explicitly stated that the waters of the North Fork and South Fork of the South 

Platte river “are separated by a high mountain range,” such that “there is not, and cannot 

be any conflict of right” between the users. Id. at 1167. In other words, there was no need 

to apply the doctrine to both the South Fork and North Fork water rights adjudicated in 

the 1913 decree because they involved “distinct and separate drainage basins.” Id. at 

1166. Indeed, we concluded, it would be improper to treat the 1913 adjudication of North 

Fork water rights as supplemental to previous adjudications of South Fork water rights. 

Id. at 1167. We further observed that water officials had consistently treated the 1913 

adjudication of North Fork rights as an original adjudication and administered those 

rights based on dates of appropriation. Id. at 1168. 
16

¶30 South Adams County was foremost a case about construing water court decrees. 

But in any event, our decision in that case does not support the water court’s reasoning 

here that the driveway intersecting the borrow ditch was functionally analogous to a 

mountain range or that the water court was required to treat the sections of the borrow 

ditch on either side of the driveway as separate sources of water. 

¶31 The water in the borrow ditch at issue here constitutes the same source for 

purposes of the postponement doctrine; the driveway does not make a difference. As the 

water court observed, water routinely flows over this driveway: It “frequently leaves the 

borrow ditch south of Culvert Number 1 and flows down to the road and back into the 

borrow ditch, eventually reaching the Huffakers’ point of diversion.” The sections of the

borrow ditch on either side of the driveway—sourced from the same fields—are not 

comparable to discrete tributaries of a river separated by a mountain range, particularly 

given that the ditch water routinely overflows the driveway and rejoins the ditch on its 

northward course. 

¶32 Section 37-92-401(b)(I), C.R.S. (2018), which defines water derived from the “same 

common source” to facilitate water division engineers’ tabulation of priorities among 

water rights, also supports our conclusion that the two sections of the borrow ditch do 

not constitute separate sources. This provision defines a common source of water as “all 

. . . waters in a water division, either surface or underground, that if left in their natural 

state would join together to form a single natural watercourse before exiting the water 

division.” § 37-92-401(b)(I). Even though the man-made driveway here interrupts the 
17

flow of water in the borrow ditch, the water south of the driveway eventually “join[s] 

together to form a single natural watercourse” north of the driveway. Id.

¶33 Thus, we conclude that the sections of the borrow ditch on either side of the 

driveway constitute the same source of water. The postponement doctrine therefore

applies to determine the relative priorities of the water rights between the Huffakers and 

Crowther because they have filed competing applications in the same source of water. 

Under this doctrine, the Huffakers’ rights are senior because they filed their application

three calendar years before Crowther. See City of Englewood, 826 P.2d at 1276. 

B. The Decrees Must Be Revised

¶34 The water court’s decrees in 13CW3012 and 16CW3013 awarded Crowther a 

conditional right to 7 c.f.s. of water in a collection area south of the driveway and the 

Huffakers an absolute right to 8 c.f.s. of water in a separate collection area north of the 

driveway. Our conclusion that the sections of the borrow ditch south and north of the 

driveway are the same source of water frustrates these terms governing the collection 

areas, which appear tethered to the water court’s erroneous conclusion that the two 

sections are separate sources. We therefore vacate the water court’s decrees in 13CW3012 

and 16CW3013 and remand with instructions to enter revised decrees so that the

Huffakers’ collection area of their absolute water right begins not at the driveway 

immediately north of Crowther’s Culvert Number 1, but farther south (upstream) at the 

Bagwells’ previously decreed point of diversion 3,377 feet south of the intersection of
