AI-generated summary, reviewed by Better Utah staff.

Aimed at directing more water toward the Great Salt Lake, this bill changes the rules for how stormwater is managed across the lake's watershed — a large area covering drainage from the Bear River, Weber River, Jordan River, Utah Lake, and Tooele Valley. Within this area, cities and counties must prioritize stormwater management approaches that allow water to soak into the ground or be reused, rather than capturing it permanently in retention basins (ponds designed to hold water indefinitely), unless no feasible alternative exists. When a detention basin — which temporarily holds water before releasing it — is required, it must be designed to release all stored water as quickly as possible without disrupting flood control.
