Why is Hecla Lake so low?We've heard your questions and wanted to share some insight. Hecla Lake is a human-made structure, but it works differently than other lakes and ponds in Louisville. While it does hold water, its main purpose is not water storage but to move ditch water through the system to 7th Generation Farm on Harney Lastoka Open Space for agricultural use. It is fed by two supply ditches that typically run from early May to early July, so the lake is naturally low in the spring before that flow begins. From the aerial photos, you can see that past years look a lot like what you're seeing now, and low levels at this time of year are not unusual. This year, Colorado's record-low snowpack means ditch flows may be limited or may not run at all, so levels could remain low longer than usual. A few other things worth knowing: - Fishing is not allowed at Hecla Lake, and the lake is not stocked by Colorado Parks & Wildlife.
- Low water levels can actually benefit ecological diversity, attracting dabbling birds and wildlife that thrive in shallow water habitats.
- The city's treated water supply is prioritized for residents, businesses, and city facilities.
Hecla Lake is a valued community and ecological asset, and we appreciate your interest in what is happening on this Open Space property. We will continue to share updates as conditions change. Let's Talk More About Water...There are currently no mandatory water restrictions in Louisville, however, PROS staff is monitoring vegetation, water conditions, and environmental impacts across all divisions and will adjust management practices as conditions change. Water management is complex, requiring thoughtful decisions about where water is most needed, how it can be used as efficiently as possible, and how to protect the community's land, infrastructure, and public spaces for the long term. How we are using water responsibly in Parks and Open Space:Parks and Public Landscapes- Prioritizing water for urban trees, newly planted vegetation, and sports fields first
- Smart controllers and weather-based scheduling minimize waste
- Overnight watering windows and cycle-and-soak methods improve efficiency and reduce runoff
- If you see irrigation running during the day, staff are likely conducting system checks or repairs, not running standard watering cycles
- Spot a broken irrigation head? Report it on the City website
Open Space- Open space areas are largely native habitat and not actively irrigated.
- Staff are monitoring ecological conditions across all managed lands and adjusting practices as needed.
- Warembourg Fishing Pond is being monitored for water level, quality, and algae. Staff will refill the pond to support the habitat as water becomes available. The pond will not be stocked this spring; stocking decisions will be made as the season progresses.
Visit the City's website for more information on the status of Louisville's water restrictions. |

The Trail/Bike Path Speed Limit Is 15,
Not Six-Sevvvennn. As daylight extends and temperatures rise, Louisville’s trails get busier with bikers, walkers, and runners. Sharing the path takes awareness and cooperation. Like driving on a busy road, everyone has a role in following the rules to keep things moving safely. Know the E-Bike Basics
E-Bikes are allowed on Louisville trails if they meet Class 1 or 2 standards (motors up to 750 watts with assistance up to 20 mph). Class 3 E-Bikes are restricted to public roads and not allowed on trails. Riders must follow all state and local laws. Know the ordinance: Louisville Municipal Code sets a 15-mph maximum speed limit for all bicycles and E-Bikes on designated trails and paths across City-owned property, including parks and open space. This limit is in place to support safe, shared use for everyone. It applies to trails and bike paths, not public roads or sidewalks. Fifteen miles per hour is the max, not the goal. Slow down in crowded areas, pass with care, and always yield to pedestrians. Help spread the word to friends and family who use the trails. A little awareness goes a long way in keeping Louisville’s paths safe and enjoyable for everyone. CYCLISTS & E-BIKES - Slow Down!
- Yield to Slower Trail Users
- Call Out When Passing
- Ride at a Safe and Controlled Speed
- Wear a Helmet
- Stay Visible
- One Person per Bike Seat
- Obey Trail & Traffic Rules
Thank you for riding responsibly, respecting the environment, and all fellow trail users! |

 Hey Louisville, Fishing Season is Here, and We Need Your Help.Staff are seeing a sharp increase in trash around ponds and lakes—fishing line, bait containers, and food wrappers. This stuff isn’t just ugly. It can injure or kill wildlife. Fishing line tangles birds and turtles, and trash ends up in the water where it lingers. Anglers can help: - Pack out all fishing line and trash
- Pick up discarded line, even if it’s not yours
- Dispose of line properly in a trash receptacle
- Encourage others to do the same
Additionally, take proactive measures: - Replace old line to prevent breakage
- Retrieve snagged line when possible
- Report injured or tangled wildlife
We’re lucky to have these open spaces and places to fish. It takes a village to help keep them clean and safe. Thank you for doing your part to help take care of them. |

 Arbor Day in Louisville: Growing Our Urban Forest TogetherLouisville celebrated Arbor Day this year with a community planting event at the Arboretum, bringing residents, staff, and special guests together to invest in the future of our urban forest. Our Forestry team played a key role in planning and preparing the site—pre-digging planting holes, organizing logistics, assisting participants with proper tree planting, and ensuring the Arboretum was clean and ready for the event. This year’s celebration aligned perfectly with the visit from our three CAPRA accreditation site visitors, who joined in the tree planting. In a fun moment, we invited the lead visitor from Ohio to help name one of the newly planted trees—unofficially dubbed “Joe Burrow,” adding a bit of personality to the day. In total, six evergreen trees and two oak trees were added to the Arboretum, enhancing both its beauty and long-term ecological value. Even as snow began to move in that afternoon, our Forestry team stayed to complete the plantings and ensure the job was done right. We invite the community to stop by the Arboretum, take a walk, and enjoy these new additions as they grow alongside Louisville’s commitment to stewardship and sustainability. |
