CA SB1026

Limits Department of Fish and Wildlife alteration agreement requirements to activities that alter the bed, channel, or bank of rivers, streams, or lakes in a manner that diverts or obstructs natural flow.

Exempts routine maintenance and repair of facilities for instream agricultural irrigation diversions from alteration agreement notification and agreement requirements.

Requires entities to notify the Department of Fish and Wildlife before substantially altering waterways, with notification including project location maps, detailed descriptions, construction plans, and copies of any related environmental or permit documents.

Allows activities to proceed without an agreement if the Department determines within 60 days that the activity will not substantially adversely affect fish or wildlife resources, or if the Department fails to issue a draft agreement within 60 days of complete notification.

Establishes that routine maintenance of water supply, drainage, flood control, and waste treatment facilities requires agreement only once, unless the work substantially changes or conditions affecting fish and wildlife resources substantially change.
