A bill for an act relating to surface water quality by requiring the establishment and maintenance of riparian protection measures, providing for financing, and providing penalties.

HF 151 requires Iowa agricultural landowners to establish and maintain riparian protection measures - such as vegetation buffers along rivers and streams - to reduce soil erosion and protect surface water quality. It defines "permanent" practices (like planting trees or grasses) and "temporary" practices (like crop rotations), making riparian buffers mandatory regardless of cost-share program availability. The bill prioritizes state funding for these measures and directs soil and water conservation districts to focus on riparian protection in their planning, aligning with Iowa's nutrient reduction strategy. It applies directly to landowners with agricultural land adjacent to waterways.
