In Weld County, yard care can turn into stormwater care

A Porch Note from Colorado Porch — plain-English local details for all 64 Colorado counties.

Clean water in Weld County often starts with ordinary yard habits. Two small things travel surprisingly far with runoff: pet waste and lawn chemicals. Left on the grass, pet waste becomes a bacterial hazard once it washes away. Fertilizer or herbicide spread right before a big storm rinses off the same way, carrying nutrients into ponds and streams instead of feeding the lawn.

The connection is easy to miss because the yard feels separate from the creek. It is not. Across a county threaded with irrigation ditches, the South Platte, and the low spots that gather snowmelt, rain links a backyard to open water faster than you would guess. A subdivision lawn, an acreage, and a rural home with a ditch out front all drain somewhere.

None of the fixes are hard. Pick up after the dog. Read product labels and follow the rates. Hold off on fertilizer and weed killer when a storm is in the forecast, and keep chemicals away from the gutter, the ditch, and any drainage path. Each habit is small on its own, and together they decide how much of your yard ends up downstream.

Weld County’s stormwater page for residents lays out the same advice if you want it in one place.
