Stream Measuring & Mapping Training Workshop August 3, 2014 Outline for Today Introduction to the Huron River Watershed Council and the Adopt-A-Stream Program Why Measure and Map? The measurements Team organization To the stream! The Huron River Watershed Council… …is a nonprofit coalition of communities and residents. …was established under state law in 1965. …protects the Huron River and its tributary streams, lakes, wetlands, groundwater and watershed. What does HRWC do? Citizen education & stream monitoring Work with local governments Stormwater Requirements Planning Mass media education and information Stream restoration projects Run a statewide monitoring network (MiCorps) Defend the river, wherever it is needed Huron RiverisWatershed What a Watershed? A watershed (or basin) is the area of surrounding land that drains into a river or creek. • 900 square miles • 63 communities • 7 counties • >525,000 people Adopt-A-Stream Program River RoundUp Aquatic Insects Tell Us the Condition of the River And Habitat conditions can help us understand the aquatic insects Outline for Today Introduction to the Huron River Watershed Council and the Adopt-A-Stream Program Why Measure and Map? The measurements Team organization To the stream! Measuring and Mapping You will be assessing the quality of the stream habitat. The measurements you take will be used to. . look for immediate problems document changes in quality interpret the biological data Diagram from Aquatic Entomology by W.P.McCafferty and A.V Provonsha compare sites Measuring the severity of human impacts to the physical environment of the stream • • • • Channel cutting and widening; erosion Sedimentation (too much sand and fine particles) Channelization- loss of microhabitats Loss of vegetation- riparian and instream Major cause: Hydrology alteration •Impervious surface •Flashiness Outline for Today Introduction to the Huron River Watershed Council and the Adopt-A-Stream Program Why Measure and Map? The measurements Team organization To the stream! Logistics of “Measuring and Mapping” • Attend this training • Join a team • The team picks a date for the event • Do the event (2-3 hours) • Return the gear What You’ll Look For 150 feet of Transects Shape of channel & bank Substrate for hiding places 300 feet of Observations The way the water flows (Pools, Riffles, Bends) Bare or eroded banks Plants in stream and on bank What is a transect? Stretch the tape measure across the stream Transects – Depth and substrate •10 transects, 15 feet apart. • Measure depth and bottom type at intervals across each transect. •Aim to have 10-15 measurements per transect (divided up evenly) Boulder -- more than 10” length or width or diameter Bigger or equal to adult head Cobble -- 2.5 - 10” Size of a fist Child’s head Rock -- 1 - 2.5” Half of a finger Size of a small fist Gravel -- up to about an inch Child and Adult Fingernails Sand -- fine particles, all about the same tiny size, gritty Fines: Clay or Muck -- finer than sand and not gritty, can’t even see individual grains (Tape measure) Hashmark is a “substrate check” Overview Transects – Waters edge width, active channel width Active Edge The waters edge width is the width of the water. The active channel is the area of normal water flow. The active channel edge is the bottom edge of vegetation on the bank. Example: Active Channel on Arms Creek Transects – Bank angle Bank Angle Transects – Bank angle Bank Angle Transects – Bank angle (undercut banks) Bank Angle What You’ll Look For 150 feet-Transects Shape of Channel – Transects Substrate for Hiding Places Bank Angles 300 feet- Observations The way the water flows (Pools, Riffles, Bends) Bare or Eroded Banks Plants in Stream and on Bank Pools. An area of water deeper and slower than average. Often found on outside of bends where there is more erosion. Pools, riffles, bends 2 bends pool pool This is an idealized rule of thumb Riffle. An area of choppy or turbulent water. Often shallower water than the average depth of stream. Often caused by rocks or obstructions in the water. Sometimes on the inside of bends where it tends to be shallow. Pools, riffles, bends 2 bends This is an idealized rule of thumb III.Stream Substrate: Embeddedness Tips: 1) Look in a riffle (preferred) or fast moving area 2) Pull a cobble or boulder out to see how much of it is buried V. Bank Stability: % Bare Banks What % of the banks are bare (showing soil) ABOVE the Active Edge? Look at the bank bare areas above the Active Edge Active Edge Where to look for bare areas Shaded area Bare areas are shaded and appear to be about 25% of the area between the Active Edge the top of the bank How is all of this used? Survey Protocol for Wadable Streams and Rivers How is all of this used? 1) Your direct observations tell us of immediate problems. 2) Tracking long term changes – 11 Metrics Add up to 200 points – Divide by 2 – Final Score: 5 (Habitat really poor) – 100 (Habitat is excellent) Metrics include: Flashiness Riparian Vegetative Zone Width Maintained Flow Volume Bank Stability Velocity and Depth Erosion Resistance Sediment Deposition Channel Alteration Embeddedness Habitat Variety Bottom Substrate, Available Cover Mapping Your Stream You will have access to previous maps. A new map is only needed if the old one is inaccurate, ugly, or hard to understand. In that case- do a better job than your predecessor! TAKE PICTURES!!!!!!!!!!!!! And give them to us! Be sure to include people and faces in your pictures as well as pictures of the creek. Safety Measure and map during low water levels You will need to wait 2 days or so after really torrential downpours. Minor rain doesn’t matter. Do only what you feel comfortable doing What not to wear on your feet If you expect to stay dry, wear waders. Tall boots are not good enough on 95% of the streams we are studying. Doing a study with boots filled with water is NOT fun. You may NOT go barefoot Do NOT wear flip-flops. You MUST wear waders in Ann Arbor area and also Mill Creek. 1) Wear Waders OR 2) wear shoes/secure sandals that can get wet Outline for Today Introduction to the Huron River Watershed Council and the Adopt-A-Stream Program Why Measure and Map? The measurements Team organization To the creek! Team Positions Goal: 3-5 people • 1 Mapper/Picture Taker • 1 Note taker • 2-3 Measurers (holding and moving tape measure, taking substrate samples) Meet your team In the next 10 MINUTES: Gather with your team by your site name. Introduce yourselves again Get your binder from Paul Make sure your contact info is right. Everyone take a color map The binder is holding your blank datasheets Fill out the team form If your whole group is here today, you can fill out the team form (your date, who does what, etc…) Give Paul or Jason a copy of the filled out form In your whole team isn’t here, in the next two days, email each other to answer the questions on your team form. • Email firstname.lastname@example.org and email@example.com with your final decisions. Planning your dates Measurements MUST be done under NORMAL or LOW FLOW conditions. Plan a rain date, and keep it open in case of high water. ALSO: Please try to do 2 outings if possible! After your first outing, talk to your team about another date that would work and be in touch with Jason and Paul who will assign you a different site. Day of the event: • Come to back door of this building • Find the hidden key to the shed • Get equipment from the shed (make sure you put in your wader/foot size to whoever picks up the equipment) • Return the hidden key to its location • Return your equipment ASAP. • Leave your binder and its contents in the shed Outline for Today Introduction to the Huron River Watershed Council and the Adopt-A-Stream Program Why Measure and Map?
