5 Watershed Management Can Prevent Problems Like These: Pesticides Found in Local Wells Managing microbes from urban watersheds can be a daunting task, as bacteria are usually present in high concentrations during storms, come from many different sources, and follow many complex pathways to reach receiving waters. Farmland: A Vanishing Legacy Managing microbes from urban watersheds can be a daunting task, as bacteria are usually When it comes to bacteria, most watershed managers have more questions than answers.

6 I m still not really sure what exactly a watershed IS.
7 What Is a Watershed? A watershed is the area of land that drains to a particular point along a stream
8 EVERYONE Lives in a Watershed
9 OK, now I know that I live in a watershed what types of things can affect the health of my watershed? High levels of paved surfaces, or impervious cover, can have many impacts on a watershed.
10 Many Forms of Impervious Cover in the Urban Landscape Sidewalks Roads Driveways Parking Buildings
11 Impervious Cover Can Transform a Watershed in Just a Few Years Agriculture Under Construction Undeveloped Developed Existing Development Undeveloped Developed 1950s 1960s 1970s 1940s 1990s
12 Stream Quality Is Related to Impervious Cover In a forest, rain soaks into the ground and is either taken up by tree roots or continues to move down through the soil and into the groundwater. When rain falls on impervious cover, it cannot soak into the ground and instead becomes stormwater runoff Inches Impervious cover produces 16 times more stormwater runoff than forest. 0 Rainfall Parking Lot Runoff Forest Runoff
13 Stream Quality Is Related to Impervious Cover 8-10% < 5% Impervious Cover 20% > 65% 30%
14 Relationship Between Impervious Cover and Stream Quality Good Impervious Cover Model Stream Quality Fair Poor Severely Damaged 10% 25% 40% 60% 100% Watershed Impervious Cover
15 Wow, there really is a relationship between impervious cover and stream health! But I want to know exactly HOW impervious cover affects stream quality.
16 How Impervious Cover Impacts Stream Quality Impervious Cover Influences: Dry & Wet Weather Stream Flow Channel Shape and Size Water Quality Plant and Animal Habitat
17 Impervious Cover Influences Dry Weather Stream Flow Many streams draw from groundwater Impervious surfaces can block water from contributing to groundwater supply This can result in lower stream flows during dry weather
18 Impervious Cover Influences Wet Weather Stream Flow When it rains, a large amount of water... Runs off of impervious surfaces Enters the stormdrain system Is directed straight to the stream
19 Impervious Cover Influences Wet Weather Stream Flow The large amount of stormwater runoff in the stream system can cause: More Frequent Flooding Higher Flood Levels
20 Impervious Cover Influences Stream Shape and Size Large amounts of stormwater runoff due to impervious cover can: Erode stream banks, making the banks steeper and the channel wider Deposit soil on the stream bottom, making the stream more shallow Cause straightening of the channel
21 Impervious Cover Influences Water Quality Pollutants build up on impervious surfaces and wash off into the stream system when it rains.
22 Harmful Pollutants in Runoff Bacteria Nutrients Pesticides Oil & Grease Muddy Water Heavy Metals (e.g. Zinc, Copper, Lead)
23 Impervious Cover Influences Habitat Quality Impervious cover changes the natural stream environment, resulting in: Smothering of Habitat by Sediment Deposits Loss of Habitat Variety Loss of Stream Buffer
24 Impervious Cover Influences Aquatic Life Impervious Cover affects many kinds of wildlife: Number and Diversity of Aquatic Life Waterfowl Aquatic Insects Amphibians Percent Impervious Cover in Watershed As the amount of impervious cover increases, Fish Photo Source: Bruce Hemboldt the number and diversity of aquatic species decreases.
25 So what does all this mean for the future of streams? With proper management, every stream can be improved.
26 What It Means for Streams Sensitive Streams Impacted Streams Diagnosis: Healthy stream Good water quality Supports diverse aquatic life Potential to be excellent < 10% Impervious Cover 10-25% Impervious Cover Very vulnerable to development Diagnosis: Classic suburban stream Water quality depends on watershed protection techniques Can support fairly diverse aquatic life Streambank erosion noticeable Prescription: Requires greatest level of protection, including land conservation Prescription: Requires extensive protection, including stormwater management.
27 What It Means for Streams Damaged Streams Severely Damaged Streams Diagnosis: 25-60% Impervious Cover >60 % Impervious Cover Channel highly eroded Poor water quality Supports very few species, no sensitive species Use of stream limited by health concerns Diagnosis: Channels are highly modified and have few natural features Poor water quality and limited aquatic life Does not support many human uses, like fishing Prescription: Careful restoration and stewardship can improve water and habitat quality Prescription: Pollution prevention can help reduce pollutants delivered downstream
28 So impervious cover can impact watersheds in many ways but is there a way our community can protect its streams? Yes! No matter where your watershed is, communities can use eight different tools to help mitigate the impacts of impervious cover.
30 Tool #1 Watershed Planning Addresses the degree and location of future development expected in a watershed Is perhaps the single most important watershed protection tool
32 Watershed Planning Choices 2 ac Residential Commercial Industrial Agriculture ½ Acre Residential Multifamily Residential 1 ac Residential Little Creek Watershed Zoning Map
33 Watershed Planning Watershed plans assess stream conditions and outline strategies to maintain or restore their condition.
34 Tool #2 Land Conservation The goal of land conservation is to keep the most important and vulnerable parts of the watershed undisturbed.
35 5 Types of Conservation Areas Critical Habitats Aquatic Corridor Cultural Areas Forests and Farmlands Water Pollution Hazards
36 Identifying and Protecting Areas for Conservation
37 Tool #3 Aquatic Buffers An aquatic buffer is a transition zone between a developed area and a waterbody Benefits of Buffers: Flood control Increase property value Habitat for wildlife Wetland protection Pollutant reduction
39 Not so good. Good.
40 NCRS Photo Gallery, 2000 Not so good. Good. Good.
41 Tool #4 Better Site Design Better site design reduces impervious cover, conserves natural areas, and provides stormwater treatment Better site design can be applied to new residential and commercial developments
42 Street Width Not so good. Good.
43 Conventional Subdivision Not so good. Cluster Subdivision Good.
44 Rooftop Runoff Not so good. Good. Good.
45 Green Parking Lots Good. Not so good. Vicki Bohnhoff,
46 Tool #5 Erosion & Sediment Control Preventing soil erosion during construction is essential for protecting streams
47 During construction, vegetation is cleared and the development site is graded to create a buildable landscape. With the trees and topsoil removed, soils are particularly susceptible to erosion. Without proper control measures, sediment from the site can run off and choke nearby streams.
48 Erosion and Sediment Control Techniques Silt Fence Hydroseeding Check dams Sediment Basin
49 Tool #6 Stormwater Management Stormwater is managed by practices that temporarily store runoff and remove pollutants. Types: Ponds Wetlands Infiltration Filtration Open Channels
50 Stormwater Management Ponds Wetlands Open Channels Filters Infiltration
51 Tool #7 Other Pollution Sources In addition to stormwater runoff there are other contributors to pollution: Septic Systems Sanitary Sewer Overflows Industrial Discharges Confined Animal Feeding Lots Illicit Discharges Marinas
54 Types of Watershed Stewardship Advocacy Maintenance Education Monitoring Restoration
