WATERSHED INTRO
WHAT IS A WATERSHED?
TOPOGRAPHY IS THE KEY WATERSHED DELINEATOR
WATERSHEDS SCALE 8 -digit HUC 11 -digit HUC 14 -digit HUC
STREAM ORDER
RIVER CONTINUUM CONCEPT Headwaters Streams heavily shaded, leaf litter is important shredders / collectors are abundant Mid-order Streams less shaded, algae more important grazers abundant Large Rivers not shaded, phytoplankton present collectors important
WHAT IS THE CONNECTION BETWEEN LAND USE AND WATER QUALITY?
WATER QUALITY • Regulated through Clean Water Act (1972) • Waters of U. S. must be “fishable and swimmable” by 1983 • Eliminate all pollution discharge to waters by 1985 Cuyahoga River, June 22 1969 http: //blog. cleveland. com/metro/2009/06/cuyahoga_river_fire_40_years_a. html
THERE IS NO SINGLE DEFINITION OF CLEAN WATER. The Clean Water Act defines clean water according to how we use it.
HOW DO WE USE WATER? • Beneficial uses: Drinking water Agriculture Industry Recreation Fisheries and other aquatic life Aesthetics
HOW DO YOU KNOW IF YOU HAVE CLEAN WATER? Water quality testing targets the pollutants that impact different beneficial uses.
POINT SOURCE POLLUTION • 25% of pollution in the U. S. • Direct discharge from industry, sewage treatment plants, etc. • Easier to identify due to “end of pipe”
NONPOINT SOURCE POLLUTION • 75% of Pollution in the US • General runoff of water contaminated by poor land use, homes, streets, air, etc. • Difficult to identify
WHY DO WE WANT TO IMPROVE WATER QUALITY? • Maintain the natural habitat for wildlife, native plants, and your community • Support designated uses of waterbody Fishable Swimmable • Protect and maintain cultural significance • Protect drinking water (public health) • Esthetically pleasing
WHAT MEASURES ARE PART OF WATER QUALITY EVALUATIONS? Biological Chemical Physical Water Quality
CHEMICAL ASSESSMENT • Dissolved Oxygen • E. coli and general coliforms • p. H • Biochemical Oxygen Demand 5 -day • Water Temperature Change • Phosphates • Nitrates and Nitrites • Turbidity/Transparency
Temp BOD Gulf of Mexico’s “dead zone”
PHYSICAL ASSESSMENT – LET’S TALK HABITAT… Some critters aren’t suited for certain situations and know when to get out!
CITIZENS QUALITATIVE HABITAT EVALUATION INDEX • The following all contribute to habitat and combine to give a final score: Substrate Fish Cover Stream shape and human alterations Riparian area and local land use Depth/Velocity Riffles/Runs
HABITAT EVALUATIONS
THE ROLE OF FLOW… • Helps provide clues to interpret water quality data • Channelization • Amount of impervious surfaces • Affect on pollutant loads & erosion • If pollutant increases in high flow, then guess NPS because concentration increases with runoff • If pollutant decreases with high flow, then guess PS because it is being diluted
BIOLOGICAL ASSESSMENT BENTHIC MACROINVERTEBRATES: WHY DO WE MONITOR THEM? • Chemistry – just a snapshot in time • Macroinvertebrates: • Not very mobile Spend extended period in the water Have different levels of tolerance to pollution Macroinvertebrates provide idea of water quality over extended period of time
5 W’S OF WATER QUALITY MONITORING
5 W’S • Why • What • Where • When • Who
WHY WE MONITOR • Identify pollutants and sources • Establish baseline data • Document changes and trends • Measure effectiveness • Inform stakeholders • Assess use attainment • Provide information and data to support modeling • Characterize watershed
MONITORING CHALLENGES • Failure to evaluate data regularly • Lack of collateral information • Poor institutional integration • No planned study design
WATERSHED INVENTORY • • Research Maps and Aerial Photos Reports & Surveys Field Inventory What are the Land Uses? In-stream Conditions Color Odor Appearance
WHAT WE MONITOR • • Determine sampling goals/objectives Environmental Community Educational What chemical and/or field samples are taken depends on objective and budget If interested in algae blooms; sample for nutrients and collect representative algae samples for id
WHERE TO MONITOR? • • Based on sampling goals/objectives Upstream / downstream At bottom of watershed Multiple sites Physical location • Safety • distance/convenience and access/property rights roadside parking, rocky inclines, high flow conditions, bacteria consideration Best habitat available should be characteristic of stream reach, yet should aim to ‘level the playing field’ between sites
WHEN TO MONITOR • Based on sampling goals/objectives • Before and After • Monitoring before and after a large rain Useful for determining types of pollutants washed into stream after rain and reveal changes that occurs as result of new land use Change Over Time Monitoring the same site twice each year for period of 5 years Useful in identifying trends and picking up unusual situations

WHY WORK WITH VOLUNTEER MONITORS • Source of credible data • More comprehensive data • Greater monitoring frequency • Larger # of sites monitored • Local knowledge • Enhances local stewardship • Gain support for your efforts • Cost effective (not cost free)
CHARACTERISTICS OF SUCCESSFUL VOLUNTEER MONITORING PROGRAMS • Well-organized • Sound scientific basis • Report results • Strong institutional support • Make a difference
QUALITY ASSURANCE/QUALITY CONTROL • Quality Assurance is a broad plan for maintaining quality in all aspects of a program • Quality Control methods are established to control errors Follow protocol Repeated Measurements Modified from a presentation given by Linda Green, Rhode Island Watershed Watch

UPCOMING WORKSHOPS • www. dnr. in. gov/nrec • Healthy Water Healthy People • March 4, Ft. Harrison SP Indianapolis, IN Hoosier Riverwatch April 9, Indianapolis and South Bend April 16, Jasper and Lake County April 23, Gene Stratton Porter April 30, Lake County
TAKE HOME THOUGHTS • Everything is connected • Use long-term thinking • Look for the big picture and relationships • Focus on object observations, not on blame • Consider how pre-existing and popular opinions inform decisions • Gather all the data that you can
