Feb. 16, 2024 Public Meeting - draft LTEMP SEIS
Channel: Bureau of Reclamation
Date: 2024-03-04

Draft Supplemental Environmental Impact Statement for the Glen Canyon Dam Long-Term Experimental and Management Plan. Reclamation held three virtual public meetings to provide information on the draft SEIS and to answer questions.

The purpose of the LTEMP SEIS is for Reclamation to analyze additional flow options at Glen Canyon Dam in response to nonnative i smallmouth bass and other warm-water nonnatives recently detected directly below the dam. The need is to disrupt the establishment of smallmouth bass below the Glen Canyon Dam by limiting additional recruitment, which could threaten populations of threatened humpback below the dam.

The LTEMP SEIS also considers the high flow experiment (HFE) protocol by including the latest scientific information to improve Reclamation's ability to implement HFE releases as originally intended in the LTEMP FEIS. Specifically, Reclamation is considering adjusting sediment accounting periods and HFE implementation windows.
