We've received disturbing information from SCWA that the lead weighted redd markers have been removed from at least one spawning study area at the head of the guide run (aka guide hole). If you have any information on who is doing this please send PM to me.
As a reminder, Solano County Water Agency is conducting a spawning study in part to determine how low flows affect spawning success. They have mapped a number of sites and are marking them with weighted rods and/or flourescent red tape attached to the creek bottom. The outcome of this study may result in changes in flows that will benefit the fish, so please do all you can to help SCWA by avoiding marked study areas and by leaving the spawners, wherever they are, alone.
I found 4 of the markers along the trail below the bridge this past Sunday. They are pretty long--like 4 feet--so it is pretty clear that people are flossing the fish on the redds and hooking the marking tape in the process. Instead of putting them back, they just chucked em up on the bank.
