The complete county distribution, spread across 16 Texas counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Texas muskrat records trace the state’s river systems, with the Trinity and Brazos corridors and the wetlands of Caddo National Grasslands anchoring the pattern. That fits the animal’s habits: muskrats build bank burrows and lodges in slow water with heavy marsh vegetation, and they rarely wander far from it.

One number stands out. Of 286 Texas records, 208 land in March alone, a lopsided cluster that’s almost certainly tied to when surveys or observation projects ran rather than a real spring surge, since muskrats are year-round residents that don’t migrate.

No NatureServe state rank is on file for Texas, so there’s no official read on how secure the population is here specifically, only the species’ globally Secure (G5) standing. The most recent listed sighting is from May 2026.
