Frequently Asked Questions

What is a Watershed?

A watershed is an area of land where surface water from rain and melting snow or ice converges to a single point, usually the exit of the basin, where the waters join another waterbody, such as a river, lake, reservoir, estuary, wetland, sea, or ocean. The watershed includes both the streams, rivers, and ditches that convey the water as well as the land surfaces from which water drains. The watershed represents an area where all the water is drained to a single point. Each watershed is separated topographically from adjacent basins by a geographical barrier such as a ridge, hill or mountain. Sometimes political boundaries influence watershed boundaries such as when man-made efforts transport water out of one watershed into another.

Why is the work of CLRMA important to me?

CLRMA is working to educate concerned citizens and lake professional alike on ways to manage this precious resource in an environmentally responsible way. Whether we’re drinking water from our tap, taking a shower, washing dishes, flushing our toilet, eating locally grown food, or enjoying wildlife near our homes. Protecting and managing the water in our lakes and reservoirs impacts our lifestyle. Our actions today can mean a better environment for future generations.

Who is CLRMA and how did they form?

CLRMA is a grass roots organization made up of individuals concerned about the future of Colorado lakes and reservoirs. Our members are people just like you - people concerned about today's lake issues.

The Colorado Lake and Reservoir Management Association was formed in 1996 as a non-profit, charitable organization. It is a statewide organization of individuals, organizations, and lake associations devoted to the protection and preservation of lakes and reservoirs. CLRMA is a recognized affiliate of the North American Lake Management Society (NALMS).

The primary objectives of CLRMA are to promote understanding and comprehensive management of lakes, reservoirs, and watersheds.

Specific objectives include:

  • Providing a forum for sharing of information and experiences on scientific, administrative, legal and financial aspects of lake, reservoir, and watershed management.
  • Foster the cooperation and interaction of public and private individuals, agencies, organizations and units of government involved in lake, reservoir, and watershed management.
  • Assist in the development of local, state and national lake and reservoir programs consistent with appropriate management strategies and techniques.

Is it okay to dump old concrete into a lake?

The short answer is a resounding No. Legal and regulatory issues aside, lakes are not dumping grounds. They are an ecosystem that supports many different types of uses. Placing concrete in a lake has the potential to introduce pollutants like automobile fluids and metal from brake pads. It also alters the depth of the lake which can negatively impact fisheries. A better use for the concrete is recycling or creating landscape walls and walkways.

Is there a list of private lakes that have lake front property on them?

CLRMA is working to answer this question by developing an interactive map. Accomplishing this is very involved and time consuming. Until the map is completed, some of the links found under the interactive map icon may be helpful in answering your question.

What is the green, paint like substance seen on lake surfaces during the summer?

During the peak algae growing season, when the days are the longest and hottest and the water is at it warmest, Blue-green algae (cyanobacteria) love to bloom at the surface of water. The bluish green "paint" that you see on the water's surface is from the destruction of cyanobacteria cells. It is important to avoid human and animal contact when this occurs. You can do your part to prevent these harmful algae blooms by picking up after your pet, using fertilizers only when need, never let fertilizer wash off your lawn or garden, and use phosphate free soaps and detergents whenever possible.

I manage a lake for my HOA. I need a resource that can walk me through how best to maintain or improve its water quality?

Check out CLRMA’s Lake Management Plan. Lake management plans assess the current condition of a lake (or lakes), including those issues and interests affecting it and provide informed recommendations to protect, manage, or improve the current condition of the lake. Take the time up front to inventory and assess your lake before spending time and money on projects that might not work.
