CORRESPONDENCE/MEMORANDUM State of Wisconsin DATE: July 8,2016 FILE REF: Sugar River,Dane Co. TO: Wendy Peich Water Regulations and Zoning Specialist FROM: Bradd Sims Fisheries Biologist,Dodgeville 1500 N Johns St,Dodgeville WI 53533 (608)935-1935 SUBJECT: SUBJECT: The Wisconsin Department of Natural Resources Fisheries Management in cooperation with Dane County and Trout Unlimited is planning an instream trout habitat improvement and stream bank stabilization project on the Sugar River located in Dane County,Wisconsin—T5N,R8E, Sec. 14,NW/4 and Sec. 11 SW/4. We are currently planning a Trout Habitat Improvement Project located on the Sugar River in Dane County. The work will take place on the above named stream as it flows through lands located in Dane County, Wisconsin—T5N,R8E, section 14,NW/4 and section 11 SW/4. The property is own by Dane County and open to public access. We would like to commence work on September 1,2016. The project would be completed in two stages. Stage one will be completed in September of 2016 with stage two being completed during June and July of 2017. The subject stretch of the Sugar River is 1.25 miles downstream if the Class II Brown trout water. The goal of the project is to enhance adult trout habitat and expand the miles of classified trout water. The Sugar River is limited in adult trout habitat through the proposed stretch. This project is designed to enhance trout habitat and increase carrying capacity for adult trout. The area to be worked on has no previous history of habitat work completed. There is a total of 2,985 feet of stream thread within the project area.Total ground disturbance is expected to be between 0.57 and 0.75 acres.The project will utilize standard trout habitat improvement techniques approved for use in southwest and central Wisconsin. This will include boom covers(6 sites covering 615 feet total),LUNKER structures(16 individual structures at 2 sites covering 128 feet total), log sills(3 sites covering 100 feet total),root wad structures(10),and bank sloping with seeding(345 feet). There will be no negative thermal impact from these structures. Please see attachments for full project design. There will also be 1 rock crossing installed. Crossings will remain for future use. There are two areas where the bank height will be reduced to help with bank stabilization and reconnecting the stream to the floodplain and historical backwaters. There is one 80 foot stretch in which rock will be installed with no sloping for bank stabilization and to protect a mature oak tree. Due to the location and size of tree,sloping is not possible without damaging the tree root system. Open soil will be mulched and seeded using a hydro-mulcher. Seed mixes will consist of native grass mix and a cover crop of oats. Mix will include but not limited to Indian grass, Canada anemone,milkweed,and big blue stem. Limestone from a local quarry will be hauled in for the project. The rock will be required to meet NRCS specifications. Rock amounts will be less than 0.75 cubic yard per linear foot. Any spoil materials will be removed from the floodway. Land use within the project area is abandoned pasture.No wetland types will be altered. There will not be any increase of upstream backwaters off the project site. There will not be a negative impact on flood conveyance resulting from the project work. Two hits occurred in the review of the NHI portal,ellipse mussel(Venustaconcha ellipsiformis)and floodplain forest community. The ellipse mussel prefers a habitat of shallow, flowing, clean small streams with stable substrate which is located within the project area. This project will maintain the habitat. The second hit was a community of floodplain forest.There is no floodplain forest community located within the project area. A review of Dane County archeological and historical sites revealed possible sites along the project corridor.Location, description,and maps of the project area have been sent to Mark Dudzik, WDNR Archeologist, for review.
