Protection Measures Selection Tool

Fish relocation and dewatering activities shall only occur between June 1 and November 30 of each year. If precipitation sufficient to produce runoff is forecast to occur while construction is underway, work will cease and erosion control measures will be put in place sufficient to prevent significant sediment runoff from occurring. Exceptions will be considered on a case-by-case basis only if justified and if precipitation sufficient to produce runoff is not forecast to occur during any of the above activities, and if approved by the NOAA RC, Corps and NMFS. If the channel is expected to be seasonally dry during this period, construction should be scheduled if possible so that fish relocation and dewatering are not necessary.
