Water plays a defining role in the natural beauty, heritage, and economy of Clark County. And, the way we use our land significantly influences the health of our waterways. The more our population grows and land is developed, the greater the strain on Clark County's numerous streams and lakes.

So, how healthy are Clark County's streams and lakes, and what are we doing to maintain and improve their condition? The Stream Health Report summarizes the current status of Clark County's streams, rivers, and lakes and provides a basis for future comparisons.
