SOIL AND WATER CONSERVATION COMMISSION – Amends existing law to provide that the commission be established in the Idaho Department of Water Resources.

H 503 moves the Idaho State Soil and Water Conservation Commission from the Department of Agriculture to the Idaho Department of Water Resources. This change affects the commission members, soil conservation districts, and state agencies that collaborate with the commission on conservation programs. The bill primarily revises the commission's administrative home while maintaining its existing structure (seven members appointed by the governor from six geographic divisions and one at-large seat) and responsibilities, such as assisting conservation districts and managing the "Idaho OnePlan" conservation planning system. The key policy change is the departmental reassignment, with no alterations to the commission's duties or membership rules.
