Mason v. Hoyle
14 A. 786, 56 Conn. 255, 1888 Conn. LEXIS 18 (1888)
Rule of Law:
The reasonable use doctrine for riparian proprietors requires mill owners to adapt their machinery and water detention practices to the stream's character and capacity, including regularly recurring dry seasons, to ensure a fair and equitable beneficial use for all downstream owners, balancing individual benefit against collective injury and established local custom.
Facts:
- Plaintiffs operate three smaller mills downstream on a river, each with small ponds and machinery that would ordinarily have an ample water supply during dry seasons.
- The defendant operates a larger mill upstream on the same river, whose machinery is greatly disproportionate to the stream's diminished capacity during dry seasons.
- For 8-9 months of each year (Sept/Oct to May/June), the river has an ample water supply for all mills, but during the remaining 3-4 months (May to Oct), the supply is comparatively small and regularly scarce.
- During these dry seasons, the defendant has detained substantially all of the natural flow of the stream for periods of 2-5 days per week to accumulate sufficient water.
- After detaining the water, the defendant runs his machinery for only 5-6 hours a day, once or twice a week, which results in the water quickly filling the plaintiffs' small ponds and then running to waste over their dams.
- The defendant’s predecessors, operating the same mill and business, used water in connection with steam power in a way that did not injure the plaintiffs.
- In 1881, the defendant repaired and enlarged his reservoir and changed the long-established mode of running the mill.
- The immemorial local custom on the stream, prior to the defendant's actions, was to let the water flow to the plaintiffs' mills without long or injurious detention.
Procedural Posture:
- Plaintiffs (lower mill owners) brought a complaint against the defendant (an upper mill owner) in the Superior Court, alleging unreasonable detention of water.
- The Superior Court made findings of fact concerning the mill operations, stream conditions, and defendant's actions.
- The Superior Court then sought advice from this appellate court (the highest state appellate court) on whether the defendant's actions constituted unreasonable detention of water, based on the found facts.

Issue:
Does an upper mill owner's practice of detaining substantially all of a stream's natural flow for several days during regularly recurring dry seasons, in order to operate disproportionately large machinery for only a few hours, constitute an unreasonable use that injures lower mill owners?
Opinions:
Majority - Loomis, J.
Yes, the defendant has unreasonably detained the water of the stream. The court holds that reasonable use of a stream must be adapted to its character and capacity, which includes acknowledging and planning for regularly recurring periods of scarcity. While a right to use implies a right to detain, this right is qualified by 'reasonable.' An upper mill owner cannot measure their rights solely by the capacity of their reservoir or selfish convenience. The court emphasizes several conditions essential to reasonable use: 1) as near as possible an equal opportunity to use; 2) adaptation to the stream's character and capacity throughout the year, treating regularly anticipated scarcity as a fixed quantity; and 3) permitting water to flow in its accustomed way, allowing each riparian owner a fair proportion of beneficial use. The defendant's machinery is enormously disproportionate to the stream's capacity during the dry season, leading to his detention of water for days to achieve only hours of operation, causing significant injury to lower proprietors for slight benefit to himself. The court also gives weight to the immemorial local custom of the stream and the comparison of benefit to the defendant versus injury to the plaintiffs, finding an extreme disparity. Public interest favors improvement of streams for all, including smaller mill owners, who should be protected from disproportionately large mills that would ruin their privileges. The fact that the defendant’s predecessors used steam power to avoid injury to others, and the defendant's continued use of steam power, indicate his machinery overburdens the water power, further supporting that his present mode of use is unnecessary and injurious. The court distinguishes precedents that focused on average flow, noting that those cases lacked the regularity of dry seasons present here.
Dissenting - Pardee, J.
No, the defendant's detention of water was not unreasonable as a matter of law. The dissenting opinion argues that the primary legal rule should encourage the fullest possible use of the stream to maximize wealth creation, by permitting a mill owner to adapt machinery to the stream's fullest capacity during its 'ordinary flow' (the nine months of abundance). The diminished flow during the three months of drought is an exception. In cases of drought where there is not enough water for full use by all, the law should prefer the proprietor whose mill is adapted to the best and fullest use of the stream during the longer period of ordinary flow. This proprietor should be permitted a right of detention to ensure some profitable use even during drought, even if it causes idleness for mills that are less adapted or allow a large portion of water to pass unused during the longer, ordinary flow period. The dissent points out that the defendant's utmost detention only allowed him six hours of use per week during drought, indicating the stream's low value to anyone during such times. The plaintiffs' misfortune, in this view, stems from their location on a stream of little value in drought and the fact that their mills are not adapted to make the best use of the stream during the nine months of ordinary flow. The dissent also states that the fact that the defendant owns a steam engine does not diminish his right to the use of water, and that existing custom allowed proprietors to detain water for profitable use. This approach aims for the most beneficial use overall, acknowledging that loss of time during drought is inevitable and the question is how that loss is apportioned.
Analysis:
This case significantly refines the 'reasonable use' doctrine in riparian rights, moving beyond a simple 'average flow' standard to incorporate the predictability of environmental conditions like regularly recurring dry seasons. It establishes a nuanced approach that seeks to balance the economic interests of individual mill owners with the equitable distribution of a shared natural resource. The emphasis on adaptation to the stream's fixed character during predictable scarcity, rather than just its average flow, has important implications for resource management and environmental law. It suggests that economic development must consider the long-term, seasonal patterns of a resource, not just its peak or average capacity, and that a use disproportionately injurious to others, even if beneficial to the user, may be deemed unreasonable. This precedent provides a framework for courts to scrutinize the scale and impact of resource use, particularly when scarce resources are at stake, and could influence future decisions regarding sustainable resource allocation.
