Buying Land in Cache County, Utah

Cache County -- Logan, Utah State University, and a valley floor that's been Utah's dairy and alfalfa leader for over a century -- runs on a genuinely agricultural economy bordering Idaho, not the dry rangeland found in much of rural Utah. It has a detailed zoning code with a documented 10-acre agricultural density standard, and it hosted its own Water Banking Act pilot project with a real, specific outcome the state hub doesn't cover.

County Zoning (Title 17)

Generally favorable

Cache County administers unincorporated land under Title 17 of its County Code through the Planning & Zoning Division of the Development Services Department. The county's A10 Agricultural zone is documented in the county's own comprehensive plan materials as a moderate-density standard of roughly one residential unit per 10 acres, with a single-family dwelling generally allowed on a smaller, already-existing lot below that threshold. Confirm the exact standard for a specific parcel with Planning & Zoning -- the county has amended Title 17 repeatedly over the years.

Cache Valley Pilot Water Bank (2023-2024)

Could not confirm

Cache County was the site of its own state Water Banking Act pilot -- the Cache Valley Pilot Water Bank, centered on southern Cache Valley near Paradise, Hyrum, Wellsville, and Mendon. Rather than forming a formal water bank, the pilot resulted in a documented two-party late-season Rental Pool lease agreement between Hyrum Irrigation Company and the Wellsville-Mendon Conservation District using Hyrum Reservoir storage. This shows water-leasing activity is real and active here, but on a narrow, specific basis between two named irrigation entities -- not a general water-banking market a buyer can tap into.

Bear River/Cache Valley Water Rights (Area 25)

Case-by-case / verify locally

DWRi administers Cache County's surface water under Area 25 (Bear River/Cache Valley), covering the Bear River main stem plus the Logan, Little Bear, and Cub Rivers, with separate river commissioners for the Bear, Logan, and Little Bear distribution systems. The valley's irrigation runs on a dense network of historic canal companies dating to 1860 (the Logan and Hyde Park Canal was among the first). As on the state hub, Cache County also sits in the Bear River basin covered by the November 2022 Great Salt Lake appropriation suspension -- confirm current status with DWRi before assuming a new appropriation is available.

Septic Near Source-Water Protection Zones

Case-by-case / verify locally

Cache County code restricts septic systems near municipal drinking-water sources: no part of a septic system is permitted within Zone 1 or Zone 2 of a designated Source Water Protection Area, though the county has considered allowing repairs (not new installs) to existing systems already in Zone 2. If a parcel is near a municipal well or spring source, confirm its protection-zone status with the Bear River Health Department before assuming a septic system is permittable.

Utah's dairy county: a real agricultural economy, and a 10-acre zoning standard

Cache County -- population roughly 145,000, about half of it in Logan, home to Utah State University -- has been Utah's leading dairy county for more than a century; the county's sheep herds grew from 10,000 in 1880 to 300,000 by 1900, and dairy cattle numbered 16,000 by 1910. Today the valley remains the state's dairy leader and a major producer of hay, alfalfa, and grain. That agricultural character shows up directly in zoning: the county's A10 Agricultural zone, under Title 17 of the County Code, is documented in county planning materials as targeting roughly one residential unit per 10 acres, with an allowance for a single dwelling on a smaller lot that already exists below that threshold -- a real, specific density standard rather than a nominal agricultural label.

Because Cache County has amended Title 17 multiple times over the years (zoning-district ordinances, use-chart and definitions amendments, and others), confirm the current version of the applicable district and its density standard directly with the Development Services Department's Planning & Zoning Division before assuming the 10-acre figure applies to a specific parcel, especially closer to Logan or one of the valley's other incorporated cities, each of which sets its own municipal zoning separate from the county code.

Cache Valley's own water-banking pilot: a real, narrow outcome worth knowing about

The state hub describes Utah's Water Banking Act pilot program in general terms and names the Price River and Snyderville/East Canyon Creek pilots specifically -- but Cache Valley ran its own pilot too, and it produced a genuinely documented, if narrow, result. The Cache Water Conservancy District volunteered southern Cache Valley (near Paradise, Hyrum, Wellsville, and Mendon) as a pilot area to address valley-wide late-season water supply and demand mismatches among irrigation companies. Rather than standing up a formal, ongoing water bank, the process identified two entities -- Hyrum Irrigation Company and the Wellsville-Mendon Conservation District -- whose supply and demand patterns fit together well enough to support a direct two-party arrangement: a late-season Rental Pool using Hyrum Reservoir storage, formalized as a water lease agreement that sets an annual process for Hyrum Irrigation Company to offer surplus late-season water to Wellsville-Mendon at an agreed price.

For a land buyer, the practical takeaway isn't that a general water-banking market exists in Cache Valley -- it doesn't yet, at least not in the way the pilot initially explored. It's that active, documented water-leasing activity between specific irrigation companies is a real and current feature of how water gets reallocated here in tight years, and it's worth asking directly whether any water right tied to a parcel you're considering is enrolled in, or otherwise affected by, an arrangement like this one.

A dense historic canal network -- and where new septic can and cannot go

Most irrigation water used in Cache Valley is diverted from mountain streams and springs -- chiefly the Logan, Little Bear, and Cub Rivers, tributaries of the Bear River -- into a dense network of canal companies with roots going back to the valley's 1860 settlement, when Logan's first major canal (the Logan and Hyde Park Canal) began delivering water to nearly 2,600 acres of farmland. DWRi administers this system today under Area 25 (Bear River/Cache Valley), with separate river commissioners overseeing the Bear, Logan, and Little Bear River distribution systems. If a parcel's irrigation water comes through one of these historic canal companies rather than directly from DWRi, confirm the specific company's own delivery rules and share allotment -- that's a separate question from the underlying water right's DWRi status.

Separately, Cache County's own code restricts septic placement to protect municipal drinking water: no part of a septic system may be located within Zone 1 or Zone 2 of a designated Source Water Protection Area. See our dedicated septic-systems page for Cache County for what that ban actually covers, the county's actual permit fee schedule, and how to check a specific parcel's protection-zone status before assuming a septic system can be installed there.

Who to Call Before Buying Land in Cache County

Cache County shares its health department with two neighbors -- the Bear River Health Department serves Box Elder, Cache, and Rich counties -- so septic permitting is a tri-county, not standalone-county, function. Well permitting and Bear River/Cache Valley (Area 25) water-right status are handled by the Utah Division of Water Rights statewide, not a county office. Questions about the Cache Valley Pilot Water Bank outcome or any current water-leasing arrangement should go to the Cache Water Conservancy District or the Utah Division of Water Resources, not county planning staff.
